FIELD SERVICE

MICRO-SEPAROMETER MARK V DELUXE OPERATION MANUAL 17.0 FIELD SERVICE The DELUXE MICRO-SEPAROMETER has been calibrated and adjusted at the factory and should require very little maintenance. This section, however, may assist in cases of minor difficulties that do not require factory service. 17.2 Syringe alert indication should a syringe alert light or light plus the audible alarm occur during testing, the following steps should be taken: Repeat the test insuring the syringe is centered in the drive mechanism and not binding. Use only a new syringe and plunger since the rubber on the plunger will swell causing increased drag. If possible, time the total syringe down time with a stopwatch. If the time is correct 45±2 seconds (mode A) or 25ą1 second (mode B) and the alert is not repeated the instrument can be put back into service. If the syringe is within normal limits and the alert system is still triggered the internal clocking system would be at fault and would require factory service. If the syringe drive time is near or above the 47 second time limit it may be due to the syringe gear lubrication. The syringe drive mechanism should be removed from the support panel and cleaned using a suitable solvent (Toluene or Kerosene) and blow dry with an air pressure source. The gears and rack should then be lubricated with Molykote. After remounting the syringe drive on the support panel, cycle the syringe drive several times and repeat the test. Should the drive time still be out of limits factory service will be required. COPYRIGHT 1984 EMCEE ELECTRONICS, INC. REVISION DATE: FEBRUARY 12, 1987 PAGE 19
