Table 9-6: Test Channel Readings (Continued)
TEST Channel Minimum* Maximum* Description
IZS TEMP 0
o
C 70
o
C The IZS temperature is set to 50
o
C. At
the setpoint, a typical reading is
3600 mV.
CONV TEMP 0
o
C 1000
o
C The Converter temperature is 315
o
C. At
the setpoint, a typical voltage is
3150 mV.
PMT TEMP 0
o
C 70
o
C The PMT temperature is unique in that
the voltage is inverse to the temperature.
A typical reading for 8
o
C would be
4200 mV.
CHASSIS
TEMP
0
o
C 70
o
C The Chassis (Box) temperature is
variable due to variable ambient air
temperature. The Box temp generally
runs about 5
o
C above the surrounding
air temp. Thus in a 25
o
C room, the Box
temp would be about 30
o
C and have a
TEST channel voltage of about
2000 mV.
DCPS
VOLTAGE
0 mV 5000 mV The DCPS is a composite of several DC
power supply voltages in the instrument.
It has been arbitrarily set at 2500 mV,
which is typical.
HVPS
VOLTAGE
0 V 5000 V The HVPS voltage is a scaled up
reading of the programming voltage
going to the HVPS. Zero to 1000 mV
corresponds 0-1000 VDC for the HVPS,
which is the maximum voltage possible.
A typical reading would be 700 mV
corresponding to 700 VDC for the
HVPS.
* Minimum and Maximum readings depend on the DAC 3 switch settings of the V/F board. For
the standard
5 VDC range, minimum corresponds to 0 VDC and maximum corresponds to
5 VDC.
