9.1.5 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). Following Table 9-6 lists the test measurements which 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 9-6: Test Channel Output
# Name Description Scaled Range
0 NONE
1 PMT READING PMT output 0 - 5000mV
2 UV READING UV lamp output 0 - 5000mV
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 o C
6 BOX TEMP Box temp. sensor 0 - 70 o C
7 IZS TEMP IZS temp. sensor 0 - 70 o C
8 PMT TEMP PMT temp. sensor 0 - 20 o C
9 CONV TEMP H2S converter temperature(H2S
version only) 0 - 500 o C
10 DCPS VOLTAGE DC power supply 0 - 5000mV
11 HVPS VOLTAGE HV power supply sensor 0 - 1000V
12 DAS AVG DAS concentration using current D/A
range 0 - Full Scale (RANGE 1)
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.
There is also a setup variable accessible through the RS-232 which controls which test measurement
is selected. This variable is called TEST_CHN_ID where ID is from 0-12 as in the table above.
