If the USB power s dsconnected and there are no batteres n the nstrument, the date and tme wll need to be reset upon subsequent power on. NOTE - On subsequent battery changes you wll have approxmately 2 mnutes to change the batteres before the clock resets. If the clock resets, the nstrument wll automatcally brng up the Date/Tme menu the next tme t s powered on n order to update ths nformaton. Ths s mportant, especally f you ntend to log data! Setup The Pro Plus nstrument has several compatble feld-rugged cable/sensor optons, each wth temperature: Cable: Cable number x Cable number x Cable number x Cable number x Cable number x Cable number x Cable number x Cable number x Avalable Sensors: DO/temp ( for lab BOD) Conductvty/temp ISE*/temp ISE*/ISE*/temp ISE*/DO/temp ISE*/conductvty/temp DO/conductvty/temp DO/conductvty/ISE*/ISE*/temp (Quatro**) *ISE (Ion Selectve Electrode) notates a port that can accept ph, ORP, Ammonum, Ntrate, Chlorde, and, n some cases, a ph/orp combnaton sensor. **Cable wll be referred to as a Quatro cable throughout ths manual. All cables come n standard lengths of 1, 4, 10, 20, and 30-meters (3.28, 13, 32.8, 65.6, and 98.4-feet) wth optons for specal order lengths up to 100-meters (328-feet) on the x cables. Contact YSI or your local representatve for addtonal nformaton. recommended for lab use or controlled condtons where a more rugged, feld cable s not necessary. These cables nclude: Cable number Cable number Cable number Cable number Cable number Cable number meter cable; sngle-juncton ph sensor 4-meter cable; sngle-juncton ph sensor 1-meter cable; sngle-juncton ORP sensor 4-meter cable; sngle-juncton ORP sensor 1-meter cable; sngle-juncton ph/orp sensors 4-meter cable; sngle-juncton ph/orp sensors Standard Pro Seres SENSOR Installaton Throughout the manual, the term sensor refers to the removable porton or electrode sensng porton of the cable assembly. For example, the DO sensor or ph sensor s the part that can be removed from a feld cable and replaced wth a new sensor. The conductvty sensor s not removable from a non-quatro cable but stll refers to the sensng porton and wll be referred to as a sensor. Ths secton covers most of the sensor nstallatons on a Professonal Seres cable bulkhead ncludng the followng sensors: Polarographc DO (black) Galvanc DO (gray) ph ph/orp Chlorde ORP Ammonum Ntrate See the next secton of ths manual for nstallaton nstructons for the Quatro cable s Conductvty/Temperature sensor. Dual sensor bulkhead ports are numbered 1 and 2, see fgure to the left. Please refer to the followng tables to determne correct sensor nstallaton nto each port of a two port cable. In addton there are several cable optons wth bult n sensors for the measurement of ph and ORP that are not consdered feld-rugged (nonreplaceable sensors, less rugged sngle-juncton sensors). These cables are 2 3

If you nstall a ph/orp combo sensor nto a cable, ORP wll not be measured. It s not recommended to use a ph/orp combo sensor on a cable. Port 1 Optons Port 2 Optons ph Polarographc DO ORP Galvanc DO ph or ph/orp none (port plug) 1020 dual cable ammonum chlorde ntrate none (port plug) If usng a 1020 cable, nstall a ph, ORP, ph/orp, Ammonum, Ntrate or Chlorde sensor n port 1 and a DO sensor n port 2. Quatro Cable (pn: ) Port 1 Optons Port 2 Optons DO Port Optons ph ph Polarographc DO ORP ORP Galvanc DO ph or ph/ ORP* ammonum chlorde ntrate ph or ph/ ORP* ammonum chlorde ntrate none (port plug) none (port plug) CT Port Optons 5560 Conductvty/ Temperature sensor only * If usng a Quatro cable, a sensor must be nstalled n port 1 for correct operaton of port 2. If you nstall a ph/orp combo sensor nto a Quatro cable, ORP wll not be measured. It s not recommended to use a ph/orp combo sensor on a Quatro cable. Before nstallng ether dssolved oxygen sensor, the nstrument must be confgured for the sensor beng nstalled. See the Setup - Dssolved Oxygen secton of ths manual for nstrument confguraton nstructons. Falure to do ths may result n damage not covered under warranty. If usng a ph/orp combnaton probe on a or cable you can report both ph and ORP. However, t s recommended to set ISE1 as ph and ISE2 as ORP n the Sensor Setup menu. The Quatro cable bulkheads are labeled 1, 2, DO, and CT, see fgure to the left. All sensors except the Conductvty/Temperature sensor can be nstalled followng the Standard Pro Seres Sensor Installaton nstructons. Conductvty/Temperature sensor nstallaton s descrbed n the next secton. For ease of nstallaton, YSI recommends that you nstall a sensor nto port 1 frst; followed by DO nstallaton, then port 2, and lastly C/T. Frst, ensure both the sensor connector and sensor port on the cable are clean and dry. To connect the sensor, grasp the sensor wth one hand and the sensor connecton end of the cable (bulkhead) n the other. Push the sensor nto the connector on the cable untl t s properly seated and only one o-rng s vsble. Falure to properly seat the probe may result n damage. Twst the sensor clockwse to engage threads and fnger tghten (Fgure 2). Do not use a tool. Ths connecton s waterproof. Please refer to the sensor nstallaton sheet that s ncluded wth each sensor for detaled nstructons. 4 5

8 Sensor Guard Fgure 2. The mage on the left shows a clean, dry sensor beng algned wth the bulkhead. On the rght, the sensor has been pushed nto the bulkhead and s beng screwed nto place. Fgure 3. The sensor(s) wll nstall drectly n the cable bulkhead. Once nstalled, the sensor guard wll protect the sensor durng samplng (DO cap membrane not shown). Conductvty/Temperature sensor Installaton n a Quatro Cable As mentoned, the nstallaton of the Conductvty/Temperature sensor (model 5560) n a Quatro cable s dfferent from all other Pro Seres sensor nstallatons. Follow these nstructons when nstallng a conductvty/temperature sensor n a Quatro cable: Locate the C/T port and, f replacng, remove the old sensor usng the nstallaton tool to loosen the stanless steel retanng nut. Once the stanless steel retanng nut has been completely unscrewed from the bulkhead, remove the old sensor from the bulkhead by pullng the sensor straght out of the bulkhead. Apply a thn coat of o-rng lubrcant (suppled wth the sensor) to the o-rngs on the connector sde of the new sensor. Sensor Cable Bulkhead Vsually nspect the port for mosture. If mosture s found, t must be completely dred pror to sensor nstallaton Algn the connectors of the new sensor and the port. Wth connectors algned, push the sensor n towards the bulkhead untl you feel the sensor seat n ts port. You wll experence some resstance as you push the sensor nward, ths s normal Once you feel the sensor seat nto the port, gently rotate the stanless steel sensor nut clockwse wth your fngers, Do not use the tool. The nut must be screwed n by hand. If the nut s dffcult to turn, STOP, as ths may ndcate cross threadng. If you feel resstance or cross threadng at any pont, unscrew the nut and try agan untl you are able to screw the nut down completely wthout feelng any resstance. Damage to your cable/ sensor may occur f you force the parts together. Once completely nstalled, the nut wll seat flat aganst the bulkhead. At ths pont, use the tool that was ncluded wth the sensor to turn the nut an addtonal ¼ to ½ turn so t cannot come loose (fgure 4). DO NOT over tghten. Do not cross thread the sensor nut. Seat nut on face of bulkhead. Do not over tghten. Please refer to the sensor nstallaton sheet that s ncluded wth the conductvty/ temperature sensor for detaled nstructons. Installng Port Plugs n Unused Ports Fgure 4. Installaton tool used to tghten stanless steel retanng nut of 5560 conductvty/temperature sensor. As necessary, nstall a port plug nto any port that does not have an nstalled sensor. Ths wll protect the bulkhead from water damage. Port plugs and a tube of o-rng lubrcant are ncluded wth all Quatro cables. These tems can be ordered separately f needed. To nstall a port plug, apply a thn coat of o-rng lubrcant to the two o-rngs on the port plug. After applcaton, there should be a thn coat of o-rng lubrcant on the o-rngs. Remove any excess o-rng lubrcant from the o-rng and/or port plug wth a lens cleanng tssue. Next, nsert the plug nto an empty port on the bulkhead and press frmly untl seated. Then, turn the plug clockwse to engage the threads and fnger-tghten untl the plug s nstalled completely. Do not use a tool to tghten the plug. 6 7

9 Connectng the Cable to an Instrument To connect a cable, algn the keys on the cable connector to the slots on the nstrument connector. Push together frmly, then twst the outer rng untl t locks nto place (fgure 5). Ths connecton s water-proof. Keypad Fgure 5. Note the keyed connector. The cable and nstrument connectors can only be mated once the keys are properly algned. Sensor Storage When a sensor s not nstalled, the sensor and cable sensor connectors are NOT water-proof. Do not submerge the cable wthout a sensor or port plug nstalled n all avalable ports. When the cable s dsconnected, the cable s nstrument connector and the connector on the nstrument mantan an IP-67 ratng. The cable assembly s suppled wth a storage contaner, or sleeve, that nstalls on to the cable. The contaner s used for short-term storage (less than 30 days). Be sure to keep a small amount of mosture (tap water) n the contaner durng storage. Ths s done to mantan a 100% saturated ar envronment whch s deal for short-term sensor storage (see Care, Mantenance, and Storage for more detaled nformaton). Do not submerge the sensors n an aqueous soluton. The ntent s to create a humd ar storage envronment. Number Key Descrpton 1 System Opens System Menu from any screen.

Pa r a m e t e r s : S e t u p, D s p l a y, Auto Stable, and Calbraton The followng secton s separated by parameter and wll dscuss sensor setup, dsplay optons, auto stable features, and calbraton procedures for each parameter. The sectons are separated by parameter due to the versatlty of the Pro Plus. You may focus solely on the parameters of your choce. For the hghest accuracy, calbrate or verfy each sensor regularly. For your convenence, YSI offers 5580 Confdence Soluton whch allows you to check the accuracy of ph, conductvty, and ORP readngs to help determne f a sensor calbraton s necessary. If you receve an error message durng a calbraton that ndcates questonable results, you have the opton to ether accept or declne the calbraton. YSI recommends that you declne a questonable calbraton snce acceptng t may result n erroneous data. After declnng a questonable calbraton, ensure the sensor s clean, the calbraton soluton s good, the calbraton vessel s clean, and that you are enterng the correct calbraton value f enterng manually. Then, try to recalbrate the sensor. If you contnue to have problems, see the Troubleshootng secton of ths manual. Temperature All probe/cable assembles, except the Quatro, have a bult-n temperature sensor. The Quatro cable shps wth a Conductvty/Temperature sensor that must be nstalled on the cable. Temperature calbraton s not requred nor s t avalable. temperature unts of F, C, or K and press enter to confrm the selecton. Only one temperature unt may be dsplayed at a tme. You may also choose not to dsplay temperature. If you choose not to dsplay temperature, other parameters that requre a temperature readng wll stll be temperature compensated. Dssolved Oxygen (DO) DO sensors can be used on X, X, X, and Quatro cables. Preparng the DO Sensor for the Frst Tme The dssolved oxygen sensor s shpped wth a dry, protectve red cap that wll need to be removed before usng. It s very mportant to put a new membrane wth electrolyte soluton on the sensor after removng the red cap. Prepare the membrane soluton accordng to the nstructons on the bottle. After mxng, allow the soluton to st for 1 hour. Ths wll help prevent ar bubbles from later developng under the membrane. Ensure you are usng the correct electrolyte soluton for the correct sensor. Galvanc sensors utlze electrolyte wth a lght blue label and Polarographc sensors utlze electrolyte wth a whte label. The dssolved oxygen sensor s suppled wth cap membranes specfc to the sensor type ordered (Polarographc or Galvanc). 5912, 5913, and 5914 membrane kts are for Galvanc sensors and the 5906, 5908, and 5909 membrane kts are for Polarographc sensors. See the Setup - Dssolved Oxygen secton of ths manual for more nformaton on the dfferent types of membranes avalable from YSI. Remove the red cap by pullng t straght off the sensor tp. Dscard or save for later use durng long term storage. Thoroughly rnse the sensor tp wth dstlled or deonzed water. Fll the cap membrane 3 4 full of electrolyte soluton, then tap the cap wth a fnger to release any trapped ar. Be careful not to touch the membrane porton of the cap. Thread the membrane cap onto the sensor, moderately tght. Do not use a tool. It s typcal for some of the electrolyte soluton to spll over. For detaled nstructons on changng a membrane cap, see the Care, Mantenance, and Storage secton of ths manual. To set the unts, press Sensor, hghlght Dsplay and press enter.

Hghlght the correct sensor type nstalled on the cable and press enter to confrm. If usng a ProBOD sensor/cable assembly, the sensor type should be set to polarographc. The Pro Plus has two compatble sensors for use wth a feld cable: Polarographc Ths sensor has a black sensor body and s engraved wth the model number Galvanc Ths sensor has a grey sensor body and s engraved wth the model number In terms of physcal confguraton, membrane materal, and general performance, YSI Professonal Seres Galvanc dssolved oxygen sensors are exactly lke the Professonal Seres Polarographc sensors. The advantage of usng Galvanc sensors s convenence. Galvanc sensors provde for an nstant-on sensor wthout the need for warm-up tme but ths affects the lfe of the sensor. Polarographc sensors last longer and have a longer warranty but requre a 5-15 mnute warmup tme before use or calbraton. u IMPORTANT The nstrument default settng s Galvanc. Please change the Sensor Type to match the correct sensor. If you observe readngs very close to 0 or extremely hgh readngs (.e. 600%), your Sensor Type settng (Polarographc or Galvanc) may be set ncorrectly and you should mmedately ensure t matches the sensor nstalled on your cable.

Hghlght Local DO and press enter to enable (Q) or dsable (P) ths functon. Local DO s a method for the Pro Plus to factor n the barometrc pressure on each DO measurement. In essence, f the barometrc pressure changes you wouldn t notce the dfference n the DO% readngs n ar-saturated water or water-saturated ar. Local DO s deal for EU complance. When Local DO s enabled, an L wll appear next to DO% on the run screen. DO mg/l readngs are unaffected by the selecton of DO Local.

The Auto Stable Senstvty can be decreased or ncreased. Hghlght Senstvty and use the left and rght arrow keys to slde the bar. The more senstve you make t (larger black bar) the harder t s to acheve stablty n a changng envronment. The Auto Stable system works by examnng the prevous 5 readngs, computng the percent change n the data and comparng that change aganst a % threshold value. The % threshold value s determned by the Senstvty bar settng. The followng chart can be used as a gude when settng the Senstvty bar. Senstvty selected by User Most Senstve, Senstvty bar s set to the far rght Example: % Data Varance Threshold 0.05% % % % 0 - Least Senstve, Senstvty bar s set to the far left 2.5% DO % wll show DO readngs n a percent scale from 0 to 500%. DO mg/l wll show DO readngs n mllgrams per lter (equvalent to ppm) on a scale from 0 to 50 mg/l. DO ppm wll show DO readngs n parts per mllon (equvalent to mg/l) on a scale from 0 to 50 ppm. Auto Stable - Dssolved Oxygen Auto Stable ndcates when a readng s stable.when Auto Stable s enabled, AS wll blnk next to the parameter untl t s stable. Once the parameter s stable, AS wll stop blnkng. To enable Auto Stable, press Sensor, hghlght Auto Stable and press enter. Hghlght DO and press enter. Hghlght Enabled and/or Audo Enabled (nstrument wll beep when the stablty The nstrument obtaned the followng data: Readng # DO% Readng # DO% Readng # DO% Readng # DO% Readng # DO% The nstrument s programmed to determne the mnmum and maxmum data value over the prevous 5 samples, and to compute the percent dfference between those values. In ths example, that gves a percent change of: % Change = 100 * (( ) / 95.3) % Change = 0.83% In ths example, f the Senstvty bar s set to the far rght, the Auto Stable requrement would not be met and AS would contnue to blnk. However, f the senstvty bar s set to the medan threshold (1.275%), the Auto Stable requrement would be met and AS would dsplay steadly on the dsplay. Wthn the Auto Stable menu, you can also choose to Hold All Readngs for as many parameters as you set for Auto Stable. For nstance, f DO and ph have 24 25

You must press the Esc key to release the held dsplay n order to take subsequent readngs Hold All Readngs must be reactvated after each use! Calbraton - Dssolved Oxygen The Pro Plus offers several optons for calbratng dssolved oxygen: DO% n water saturated ar, DO mg/l and DO ppm n a soluton of known dssolved oxygen determned by a Wnkler Ttraton, and a Zero pont. If performng a zero pont calbraton, you must also perform a %, mg/l, or ppm calbraton followng the zero calbraton. For both ease of use and accuracy, YSI recommends performng the followng 1-pont DO % water saturated ar calbraton: Salnty Correcton The last feature n the Sensor menu s the Salnty correcton value whch s used to calculate the dssolved oxygen mg/l and ammona readngs when a conductvty sensor s not n use. Press Sensor, hghlght Salnty, and press enter. Then, use the numerc entry screen to enter the Salnty value of the water you wll be testng from 0 to 70 ppt. If usng a cable wth a conductvty sensor, the salnty measured by the conductvty sensor wll be used n the DO and ammona mg/l calculatons and As Measured wll be dsplayed next to Salnty n the Sensor menu. As the salnty of water ncreases, ts ablty to dssolve oxygen decreases. For example, fully oxygenated 20 C water at sea level wth zero salnty wll hold mg/l of dssolved oxygen. If that same sample had a salnty value of 9 ppt, then t would hold mg/l of dssolved oxygen. Therefore, to obtan accurate mg/l readngs, t s mportant to know the salnty of the water you wll be testng and to nput that value nto the nstrument. The salnty of fresh water s typcally ppt and seawater s typcally 35 ppt. You wll also have the opportunty to enter or modfy the Salnty correcton value durng DO calbraton. It s not necessary to calbrate n both % and mg/l or ppm. Calbratng n % wll smultaneously calbrate mg/l and ppm and vce versa. Calbratng DO % n Water Saturated Ar: 1-Pont Calbraton The suppled sensor storage contaner (a grey sleeve for a sngle port cable or a screw on plastc cup for the dual-port and Quatro cables) can be used for DO calbraton purposes. Mosten the sponge n the storage sleeve or plastc cup wth a small amount of clean water. The sponge should be clean snce bacteral growth may consume oxygen and nterfere wth the calbraton. If usng the cup and you no longer have the sponge, place a small amount of clean water (1/8 nch) n the plastc storage cup nstead. Make sure there are no water droplets on the DO membrane or temperature sensor. Then nstall the storage sleeve or cup over the sensors. The storage sleeve ensures ventng to the atmosphere. If usng the cup, screw t on the cable and then dsengage one or two threads to ensure atmospherc ventng. Make sure the DO and temperature sensors are not mmersed n water. Turn the nstrument on and wat approxmately 5 to 15 mnutes for the storage contaner to become completely saturated and to allow the sensors to stablze. Press Cal.
