2 GENERAL DESCRIPTION & FEATURES Thank yu fr yur purchase f Delmhrst Instrument C s HT-4000 handheld thermhygrmeter. The HT-4000 ffers the latest in features and functinality., The meter is easy t perate, measures ambient temperature, relative humidity, and calculates dewpint, abslute humidity (grains per pund), and vapr pressure. We recmmend that yu read the fllwing pages in detail t take full advantage f all that the HT-4000 has t ffer. NOTE: THE HT-4000 AND HT-4000F ARE THE SAME INSTRUMENT. THE HT-4000F DESIGNATION INDICATES THE METER IS SHIPPED WITH THE RH/T-S3 SENSOR THAT COMPLIES WITH ASTM F2170 FOR IN-SITU TESTING OF RELATIVE HUMIDITY IN CONCRETE FLOOR SLABS. THE HT-4000 IS SHIPPED WITH THE RH/T-S1 SENSOR FOR WATER DAMAGE RESTORATION AND GENERAL INDUSTRIAL APPLICATIONS. Specificatins: Measures RH ver the range f 0-100% (with accuracy f +/- 2% ver 10%-90%) Measures temperature ver the range f -40 F-255 F with accuracy f +/- 1.8 F ver -4 F t 158F (range f -40 C C with accuracy f +/- 1 C ver -20 t 70 C) Calculates Dew Pint ver the range f -40 F F (-40 C - 80 C) Calculates GPP (Grains Per Pund) when in Fahrenheit mde ver the range f GPP Calculates GPK (Grains Per Kilgram) when in Celsius mde ver the range f GPK Calculates PSI (Punds Per Square Inch) when in Fahrenheit mde ver the range f 0-7 PSI Calculates KPA (Kilpascals) when in Celsius mde ver the range f 0-47 KPA Operating temperature - -4 t 158F (-20 t 70C) Sensrs - RH/T-S1 fr water damage/restratin and general industrial applicatins; RH/S3 fr in-situ cncrete flr slab testing (ASTM F2170) Features: Detachable RH Sensr with ptinal extensin cable (RH/T-C1) LCD backlit display 9V battery (included) 1-year warranty Carrying Case (included) 1

3 OPERATING INSTRUCTIONS -USER GUIDE- This guide prvides step-by-step instructins n pwering up, using and pwering dwn the meter. NAVIGATION: The meter uses an n-screen, menu-driven apprach t navigate thrugh the meter features, allwing fr an intuitive understanding f keypad functins. Each screen presents the user with a number f selectable ptins. One f the ptins is always selected and the user can mve (navigate) the selectin t any ther available ptin. The keypad is aimed at prviding navigatinal cntrl, and nt at accessing specific features. There are fur directinal keys aligned intuitively arund a middle (fifth) key (see Figure 1): Abve (UP), belw (DOWN), t the right (RIGHT) and t the left (LEFT). The middle key is used t SELECT the ptin highlighted n the screen. Fr purpses f this wner s manual, the five keys will be referred t as and SELECT. Fig. 1 Keypad Layut 2

4 INSTALLING THE BATTERY: The battery cmpartment is lcated n the underside f the case, at the bttm f the handle. 1. Open the battery cmpartment by sliding the lid back while pressing n the release indent. 2. Ensure crrect plarity, and push the battery in flush with the bttm bard until the cnnectrs snap tgether n bth sides. 3. Replace the battery cmpartment lid. LOW BATTERY: The meter features a battery status mnitr, designed t warn the user as well as prtect measurement accuracy frm impending battery failure cnditins. The battery warning is triggered by either cntinuus r temprary lw vltage cnditins. Visible (a battery icn n the tp right side f the display) and audible (buzzer warble) indicatrs accmpany a battery warning. Once a permanent lw battery cnditin is detected, all measurement functins are disabled. Enugh pwer remains fr ther menu functins, but almst any user actin at this time causes a lw-battery warning t be generated. The battery shuld be replaced immediately. If the battery reaches critical levels, the meter will refuse t stay n at pwer-up. This gradual warning system is intended t prvide the user advanced battery status ntice and give ample time fr replacement befre peratinal limitatins ccur. TO POWER THE METER ON: METER USE 1. Befre turning n the meter, firmly insert the sensr int the tp f the meter, making sure t align the pin-ut n the DIN cnnectr. 2. T turn the meter n, press and hld the SELECT buttn fr apprx. 2 secnds. The first screen will temprarily display the meter name (HT-4000) and the sftware revisin level. Refer t this revisin number whenever yu call Custmer Service. 3

5 3. The meter will display the main RH Measurement screen, as shwn belw: 4. The meter will begin taking readings. As a default setting the RH reading will be the mst prminent n the screen. If yu wuld like t make anther variable (temperature, GPP/GPK, PSI/KPA r dew pint) the prminent reading, use the and keys t highlight yur selectin. Press the SELECT key t chse that variable. O POWER THE METER DOWN: 1. T pwer the meter dwn, highlight OFF using the and keys, and press SELECT. 2. Alternatively, if n keys are pressed fr 2 minutes, the meter will pwer dwn autmatically. FAHRENHEIT / CELSIUS MODE TOGGLE 1. T switch between Fahrenheit and Celcius measuring mdes, use the keys t highlight F-C. 2. Pressing SELECT will tggle between Fahrenheit (degrees F, GPP, PSI) and Celsius.(Degrees C, GPK, KPA) mdes TO HOLD METER READINGS ON-SCREEN 4

6 1. T hld a reading n-screen while in measuring mde, press the SELECT key. 2. Press the SELECT key again t resume taking cntinuus readings. EASURING RELATIVE HUMIDITY IN CONCRETE FLOOR SLABS IN ACCORDANCE WITH ASTM STANDARD F2170 USE SENSOR RH/T-S3 Select test lcatins t prvide infrmatin abut misture distributin acrss the entire cncrete slab, especially areas f ptentially high misture, r if the slab is thick (>4 in.) and air circulatin is pr. Fr slabs n-grade and belw-grade, include a test lcatin within 3ft f each exterir wall. Perfrm minimum three tests fr the first 1000 ft sq and at least ne additinal test fr each additinal 1000 ft sq. 1. Drill a 5/8 hle t a depth f 40% f the slab thickness using a rtary hammer drill. Use a drill bit specially designed fr rtary drills and with 3 r 4 cutting edges t insure a smth, rund hle. Surface preparatin is nt required. 2. Vacuum the hle thrughly, then use a wire brush t clean and lsen any cncrete remaining in the hle. Vacuum again and repeat the prcess a secnd time. 3. Insert the yellw sleeve int the hle. Use silicne (r ther water-resistant sealant) t seal the interface between the cllar f the sleeve and the cncrete surface. Use a hammer t insure the sleeve is fully inserted int the hle and sealed t the cncrete. 4. Insert the prtective yellw cap int the sleeve and let the hle acclimate fr 72 hurs. 5. Remve the cap and immediately insert the sensr t full hle depth. Wait minimum 1h and then take RH readings by cnnecting ne end f the RH/T-C1 cable t the tp f the meter and the ther end t the expsed cnnectr n the sensr husing. Check fr drift. The meter reading must nt drift mre than 1% RH ver 1 hur. 6. Alternately, insert the RH sensr int the sleeve immediately after setting the sleeve. Readings can then be taken as sn as the hle has acclimated. 5

7 The cmplete ASTM dcument is available at: CAUTION - ABOUT THE RH/T SENSOR Cntinued expsure t high temperature and humidity, chemical vaprs, and any ther crrsive envirnment will accelerate inevitable sensr aging, lss f calibratin, and pssible permanent damage. The sensr always must be stred inside the puch in which it was received and in a clean, dry place when nt in use. It is best t keep the meter and sensr in the carrying case. We recmmend checking calibratin peridically with either a reference sensr which is kept strictly fr this purpse, r a salt slutin. Bth are available frm Delmhrst r yur supplier. CARE OF YOUR METER Stre yur meter in a clean, dry place. The prtective carrying case prvided is an ideal strage place when the meter is nt in use. If the meter has been left in a ht r cld envirnment vernight r fr an extended perid, allw the meter t acclimate t the temperature cnditins in which it will be used fr minimum 1-2 hurs, r as lng as pssible. Clean the meter with any bidegradable cleaner. Use the cleaner sparingly and n external parts nly. Keep cleaner ut f the sensr input cnnectr. After each use, place the RH/T-S1 sensr in the static-free bag it was shipped in and keep in the carrying case r a clean, dry envirnment. Remve the battery if the meter will nt t be used fr ne mnth r lnger. SERVICE FOR YOUR METER If yur meter is nt wrking prperly r yu believe it t be giving errneus readings, replace the battery with a new ne.and/r try using a new sensr. If either f these steps des nt reslve the prblem, g t and fllw the instructins under the Prduct Supprt tab.
