Table 10-1: Test Functions (Continued)

Test Function	Factory Set-Up	Comment
DCPS	2500 ± 200 mV	DCPS is a composite of the +5 and ± 15 VDC supplies. It has
		been arbitrarily set at 2500 ± 200 mV. If it is not in this range
		one of the voltages in the supply is not working. Check the
		procedures for diagnosing the Power Supply Module.
RCELL TEMP	50.0 ± 1°C	The reaction cell temperature is controlled to 50°C ± 1°C by
		the computer. It should only read other values when the
		instrument is warming up. If the value is outside the
		acceptable range, go to the procedure for diagnosing the
		Reaction cell temp supply. The alarm limits are less than 45°C
		and greater than 55°C.
BOX TEMP	8 - 48°C	The Box Temp is read from a thermistor on the Status/Temp
		board (01086). It should usually read about 5°C above room
		temp. The M100AH is designed to operate from 5 to 40°C
		ambient. Therefore the box temperature should be in the range
		of about 10 to 50°C. Temperatures outside this range will
		cause premature failures of components, and poor data
		quality. Warning limits are < 8°C and > 52°C.
PMT TEMP	7.0 ± 1°C	The PMT detector is very temperature sensitive. The PMT
		temperature should always be near 7°C, except at power-up.
		Temperatures more than ± 1°C from the set point indicate
		problems with the cooler circuit. See Section 10.3.9 for PMT
		cooler diagnostic and troubleshooting. Warning limits are <
		2°C and > 12°C.
TIME		This is the time of day clock readout. It is used to time the
		AutoCal cycles. The speed of the clock can be adjusted by the
		CLOCK_ADJ variable in the VARS menu. The clock can be
		set via SETUP-CLOCK-TIME from the front panel.
