4. Troubleshooting

Introduction All troubleshooting must be performed by qualified service technicians who have basic electrical troubleshooting skills and the proper equipment (i.e., voltage meter). This manual does not imply a license to troubleshoot or perform repairs without proper qualifications. CAUTION: Some troubleshooting requires the instrument to be turned on while the cover is removed. Use extreme caution when operating the instrument without the cover. Hazardous voltages are present at the AC input and power supply. The troubleshooting chart in this section lists problems that may occur while operating the instrument. The left column describes the symptom, the middle column lists checks to determine what is causing the problem, and the right column suggests an action to resolve the problem. Follow the checks in the order they are listed. If you perform checks out of order, you risk replacing the wrong part. If, after performing all checks, there is still a problem, call the Fiske Associates Product Service Department. See Service Assistance (Section 1 - Introduction) for the appropriate phone number to call. Diagnostic Menu The Diagnostic Menu [DIAG] contains items that allow discrete testing of each component of the instrument. Enter the Diagnostic Menu by scrolling to it, and pushing the [DIAG] button. A description of the available tests follows. 1. A/D Tests A/D Tests are designed to check the performance of the cooling assembly, and the efficiency of heat transfer between the components of the cooling assembly. The result of an A/D Test gives a "duty cycle", expressed as a percentage indication of how much power the thermoelectric cooler uses to reach an operating temperature sensed by the block probe. An increasing duty cycle indicates deteriorating performance of the cooling assembly. Pressing the left button will change the set or selected cooling assembly temperature. Pressing the right button will change the display from resistance to temperature. The sample probe readings are also displayed. 2. Probe Bin Test The bin test is used to determine the resistance of the sample probe at a specific temperature. (-0.093 C is used for convenience, which corresponds to the 50 mosm/kg calibration standard.) When a new sample probe is installed, the bin number must be determined and entered into the instrument from the Setup Menu. With age or hard use, the resistance of a probe may change. It is therefore useful to recheck the bin test as part of a routine diagnostic check. 3. Solenoid Test The Solenoid Test will manually trigger the freeze solenoid. The solenoid should give an audible impact immediately on pressing the [START] button. 4. Display/Print Test This test sends a complete character set to the display, serial port and printer port. This test will identify any problems with these areas. 5. Key/Beeper Test Proper function of the keypad can be confirmed by this test. As each button is pressed, [*******] appears above the button and a beep is heard. 29 Fiske Micro-Osmometer Service Manual

6. Barcode Test This menu selection is for testing a barcode scanner. Scanned information will appear on the display, and a short beep will occur. Additional scans may be performed until the test is cancelled. Please note that the barcode scanner may also beep, if its beeper is not disabled. Exit Returns the user to the "Osmometer Ready" prompt. Fiske Micro-Osmometer Service Manual 30

Installation Please follow the precautions listed below when setting up your printer. They are designed to help you keep your printer working at its best. 5. Slide the paper through the slot between the paper compartment and the printer compartment. You can slide the paper in about one-quarter inch before it stops. Plug your printer into an appropriate grounded outlet. Place your printer on a flat hard surface, like a tabletop. Keep your printer out of direct sunlight. Connect the centronics cable to the 36-pin centronics connector on the printer, and then connect the DB25 cable to the female DB25 connector on the back panel of the instrument. Connect the DIN cable to the printer power jack on the back panel of the instrument, and then to the DC input on the printer. Installing the Paper 1. Remove the printer cover by pressing on the groove pattern to pop the front edge up. Lift off the cover. 2. Press the rocker switch to the left. The light will go off. 6. While holding the paper in place, press the rocker switch to the paper feed position. The printer will activate, and a rubber roller will pull the paper into the printer compartment. Hold the switch in the paper feed position until the paper emerges from the top of the printer mechanism. 7. When an inch of paper has emerged from the top of the printer, release the paper feed button and pull the paper through the printer until several inches are exposed. 3. Unroll several inches of the paper. 4. Cut a straight edge on the paper roll if it is jagged. This will facilitate inserting the paper into the printer. 8. Slide the paper through the slot in the printer cover. 210P550 Rev0 (210550) Page 2 of 7

2. Push down on the embossed grooves on one or both sides of the printer cover until the printer cover tilts. 9. Push the back of the printer cover down and into place. 10. Press the front of the printer cover down to lock in place. 3. Lift off the printer cover. Push down on the right side of the ribbon cartridge where it is marked PUSH, and remove the cartridge. 4. Install the new cartridge. Be sure the ink cartridge is inserted firmly to prevent weak or irregular printing. The cartridge must be properly seated and aligned for best printing. Changing an Ink Ribbon When printing becomes faint or difficult to see, the ribbon may be dried out or in need of replacement. Before replacing the cartridge, try advancing the ribbon to a new section by holding down the paper feed switch for several seconds. 5. Turn the cartridge clockwise (marked by an arrow) to stretch the ribbon. If the print impression is still weak, purchase a new ribbon cartridge (Product #330541) and install it using the following instructions. 1. Turn the printer offline by pressing the left side of the rocker switch. The light should go out. 6. Replace the cover. Replace the paper. 210P550 Rev0 (210550) Page 3 of 7

Appendix C Product Disposal and Recycling

Product Disposal and Recycling International concern about environmental pollution resulting from improper disposal of products and materials at the end of their useful life has resulted in an increase in legislation to control the methods and procedures used to handle waste electrical and electronic equipment. While the regulatory status in some regions of the world has progressed to the point where formal legislation is already in effect, many other regions are in the process of creating similar legislation or adopting that already in existence in other areas. The result in the years ahead will be more stringent control over disposal of products and recycling of their components once they are withdrawn from use. and restrictions in effect to ensure proper disposal, and available locations where products can be sent.
