OPTIONS AND ACCESSORIES
External Voltage Stabilizer
Filters input power to the test set and guards against line
voltage fluctuations that may cause inaccurate readings.
Strip Chart Recorder
Document and print test sample leakage current
measurements at the test site. This portable analog chart
recorder features two ranges (50 and 500 mA), with
results printed on pressure-sensitive paper.
Dimensions:
9 H x 7.5 W x 7.4 D in. (230 H x 190 W x 190 D mm)
Weight: 6 lb (2.7 kg)
Special Cable Lengths
For a nominal charge, a custom-length, shielded, high-
voltage output cable up to 50 ft (15 m) can be supplied.
Specify length when ordering.
High-voltage Discharge and Grounding Stick,
ratings 70/120/160 kV
Applications Guide
A practical guide, “Lowdown on HV DC Testing,” gives the
what, when, how and why of high-voltage dc testing and
its applications.
High-Voltage Discharge and Grounding Stick
Applying a suitably rated high-voltage resistance discharge
stick following a test is recommended. This is not only a
good safety practice, but will hasten discharge of highly
capacitive samples.
