High Voltage Tests
The subsequent functions or ranges request verification with a high voltage source. Use a
Chroma 19052 HIPOT Tester as the source for ac and dc voltage and check the actual output
value with a 10 kV standard divider and a Fluke Calibration 8588A multimeter. Use
for
these tests.
Follow these steps to verify the high voltage functions.
1. 5 kV dc voltage input test:
a. Connect the 19052 output terminals to the HV and COM input terminals of the Product.
b. Use a 5 kV test lead from the 5322A accessory on the high voltage side.
c. Connect the grounding post on the Resistance multiplier to the Product rear panel
grounding post.
d. Select the
METER
function on the Product. Push the
Input
softkey to activate the HV
input terminal.
e. Select
HV (Max 5kV).
f. Push the
AC/DC
softkey to set the mode to
DC
.
g. Set 4 500 V dc on the 19052. Switch the 19052 output terminals ON.
h. The Product should read within the limits of 4 481 V to 4 519 V.
2. 5 kV ac voltage input test:
a. Connect the 19052 output terminals to the Product HV and COM input terminals.
b. Use a 5 kV test lead from the 5322A accessory on the high voltage side.
c. Connect the grounding post on the Resistance multiplier to the Product rear panel
grounding post.
d. Select the
METER
function on the Product.
e. Push the
Input
softkey to activate the HV input terminal.
f. Select
HV (Max 5kV).
g. Push the
AC/DC
softkey to set the mode to
AC
.
h. Set 4 500 V ac on the 19052. Switch the 19052 output terminals ON.
i. The Product should read within the limits of 4 481 V to 4 519 V.
