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.

4 SAMPLE FLOW
5 RCELL TEMP
6 BOX TEMP
7 IZS TEMP
8 PMT TEMP
9 CONV TEMP
10 DCPS VOLTAGE
11 HVPS VOLTAGE
12 DAS AVG
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.
