10.1.5 Test Channel Analog Output

Many of the TEST functions have an analog voltage associated with them. As a diagnostic aid it is possible to route any one of the various test voltages out the 4th analog output port (see Figure 2-2). Table 10-6lists the test measurements that may be routed to test channel output. To route an analog test measurement to test channel output, press SETUP-MORE-DIAG-ENTR and use the PREV or NEXT buttons to scroll to the TEST CHAN OUTPUT and press ENTR. Press the PREV or NEXT buttons to scroll to the desired measurement and press ENTR.

Table 10-6: Test Channel Output

#	Name	Description	Scaled Range
0	NONE
1	PMT READING	PMT output	0	- 5000 mV
2	UV READING	UV lamp output	0	- 5000 mV
3	SAMPLE PRESS	Sample pressure sensor	0	- 40 in-Hg
4	SAMPLE FLOW	Sample flow rate	0	- 1000 cc/min.
5	RCELL TEMP	Reaction cell temp. sensor	0	- 70°C
6	CHASSIS TEMP	Inside of chassis temp. sensor	0	- 70°C
7	PMT TEMP	PMT temp. sensor	0	- 20°C
8	DCPS VOLTAGE	DC power supply	0	- 5000 mV
9	HVPS VOLTAGE	HV power supply sensor	0	- 1000 V

When a measurement other than NONE is selected, an additional test measurement appears on the display, which has the format "TEST=XXXXX.X MV" and shows the mV value currently being output to test analog output port.
