48 . Service Functions The Service Functions mode provides a menu of service test functions to assist in failure diagnosis and identification. A logic flow chart is provided for reference of the sequences included in the Service Functions mode. TEST ELECTRODES This mode allows for the measurement and display of electrode voltages. Standard A, Standard B or an external sample can be measured to determine electrode performance and provide measurement data useful in locating electrode calibration faults. Each electrode parameter will be displayed and the electrode voltage associated with the sample type selected can be observed. Example Displays: Std. A: Na=58 Std. B: Na= K= 65 Cl=-90 K=-988 Cl=6 Ext: Na= K=-598 Cl= - TEST SAMPLE SENSOR In this mode, the sample sensor output is displayed which is useful for electrical adjustment or for troubleshooting sample sensor faults. A dry sample sensor should display a value of 00 with a range of 80 to 0. After verifying a dry sensor, aspiration of a clear fluid (i.e., water) should increase the displayed value by at least 0 units. Example Display: DRY 80-0: 0 External: 5 =Pump/=Exit Pump: =OFF

49 TEST SnapPak SENSOR (980 and 98 only) In this test, the SnapPak Sensor detects whether the ISE SnapPak is in place. "I" indicates that the ISE SnapPak is in place, "O" indicates that it is either not present or not completely seated. Example Display: SnapPak: I I = IN O = OUT TEST LANGUAGE SWITCH (980 and 98 only) This mode displays the language selected for display and printout. To change the selection, set the language switch (located behind printer) to the desired language. The display will indicate the language choice according to the switch setting. To activate a new language, turn the analyzer off and back on with the switch set to the desired language. Example Display: Lanugage Switch English TEST SAMPLE DOOR (except 98) This test verifies the operation of the sample door light gate and its associated circuitry. The display indicates an O or C depending on the position of the door. Example Display: Sample Door: C C:Closed/O:Open

50 TEST PROBE (98 only) This test verifies the operation of the sample probe motor, position sensor and associated circuitry. The "U" represents the output of the upper position sensor, the "L" represents the output of the lower position sensor. Example Display: U = 0 L = Sample Position? TEST AUTOSAMPLER (98 only) This test verifies the operation of the Autosampler turntable assembly. The display indicates the output of both the position and home sensors. te: If the Autosampler is not plugged in or the TABLE PRESENT bit is not activated, this test will not appear under the SERVICE FUNCTIONS menu. Example Display: Home: 0 Pos = TEST PUMP This test turns on the peristaltic pump at each of the four pump speeds. The display indicates for two seconds each pump speed while each pump speed is being tested. Observe that the peristaltic pump changes speed as is indicated on the display. *** Pump Test *** *** Pump Test *** Very Slow Speed Slow Speed *** Pump Test *** *** Pump Test *** Medium Speed Fast Speed

51 TEST PINCH VALVES This test turns on/off each solenoid valve as indicated and is useful to verify both electronic control and mechanical operation of each solenoid valve. TEST INTERFACE The Interface Test can be used to verify correct operation of the RSC serial port. To operate this test, jumper pin and pin of the rear interface connector prior to invoking the test. During the interface test, the analyzer sends out a test string and checks if it is received within a set period of time. If correct operation is observed after completion of the test, INTERFACE OK will be displayed. TEST AMPLIFIER The Amplifier Test displays ground, reference and output voltage of each input amplifier. The values displayed for each electrode channel will be dependent on the electrode inputs and may vary. Display of the ground should read between -0mV and +0mV with the reference voltage reading between -90mV and -50mV. With all inputs open, the display should read +/- 095 for each channel. On the 90/ 980/98, an additional display indicating the temperature voltage and temperature in degrees C is available to verify the temperature adjustment. ENTER SERVICE CODE Service Codes are available and allow additional programming features. Following is a listing of the available Service Codes and functions: Set Reset Service Code Description ALL LLA This service code will enable the Ca ++ value during auto- (98 only) matic serum/blood measurement. Special precautions are necessary to obtain the correct Ca ++ value due to sample exposure to room air. CDC Clears all Service Codes. 5

52 DEC CED Provides one additional digit of resolution for each measured parameter for blood and serum samples. QC and Standard samples are always displayed with high resolution. Urine samples are always displayed in low resolution. ECO OCE Allows the operator to run the instrument in the economy mode. The instrument will enter the STANDBY MODE. This occurs at the time of the next -point calibration when no samples have been analyzed since the last -point calibration. FIF IFI Allows printing of electrode voltages during printout of measurements and calibrations. (not available for 90) LEM MEL This service code will print the last 0 error messages (980/98 only) with the date and time of occurrence. MGL LGM This service code is available only in the model 90/ 980/98 analyzer and enables Ca ++ values to be displayed in mg/dl. The normal mode displays values in mmol/l. QC and Standard results are always displayed in mmol/l. B BON (980 /98only) QCC CCQ This service code disables the beep. When this code is enabled, QC values will be reported in direct ISE measurement instead of flame-equivalent values. In this mode, correlation factors are T applied to the measured values. SFC This code allows the input of a percentage for the ISE (980/98 only) SnapPak TM counter. SLC CLS When this code is set, the current setting of the leasing (980/98 only) counter, which cannot be reset by the operator, is printed on the calibration report. SSC CSS This code toggles needle height to accommodate smaller (98 only) sample cups. In the default setting, the analyzer works with.0 ml cups. To select 0.5 ml sample cups, SSC has to be activated. To return to the default setting, CSS has to be activated. 6

54 Description of Modules. Mechanical Assemblies.. Front Door Assembly For the 90, 0, 0 and 80 analyzers, the front door can be removed by moving the analyzer to the edge of a work surface so the analyzer door, when opened, will extend past the edge of the work surface. With one hand, hold the analyzer door near the right side hinge pin and, with the other hand, gently apply pressure to the middle rear area of the door. This will allow the right hinge pin to clear the retaining hole in the main chassis. The door can then be removed from the analyzer. The 98 front panel can be removed by tilting it slightly away from the analyzer and lifting it straight up. The plastic window can also be replaced in the field by gently pressing from the rear of the window and snapping the plastic window out toward the front of the analyzer door. The door magnets cannot be replaced in the field as they are glued in place with conductive adhesive... Needle Unit Assembly Both sample needle and fill port are designed for easy replacement by the user. To remove the fill port assembly for replacement, pull the fill port holder towards the front for easy access. Then, press the two plastic tabs on the fill port to allow removal of the fill port from the fill port holder. The sample needle can also be removed and is supplied as a one-piece assembly including the intake tubing. To remove the sample needle, grasp the needle near the white holder block and pull up to unsnap the sample needle from its position. To replace the assembly, align a replacement sample needle and press the replacement assembly into place. Three screws located on the left side of the assembly hold the needle unit assembly in place. To access the two rear screws, turn power off and remove the rear panel. The rear panel can be moved away from the unit for easier access by unplugging the wire harness from the power supply. The SBC board can now be removed by removing the screws which secure the SBC board and disconnecting the cables on the SBC board. Disconnect the connector to the lamp board which supplies the Door Open signal. The two rear screws which secure the needle unit can now be removed using an Allen wrench. Then, remove the front securing screw, the sample intake tubing and the reagent supply tubing (red tag) from the fill port. The needle unit can now be removed from the front of the analyzer for replacement. Reference the Illustrated Parts diagram in Section 8 for a detailed parts diagram of the needle unit. 8
