Leakage current judgement (insulation resistance testing)
For insulation resistance testing, in addition to the conventional judgement method
using resistance values, the tester can also perform judgements using the value of
the leakage current that flows through the insulation resistance.
■
Fully programmable GPIB and RS-232C interfaces as a
standard feature
All functions except for the POWER switch, KEYLOCK, and program execute
(AUTO) functions, are remote-controllable. Test conditions such as the test voltage,
judgement value, and test time can be controlled remotely in DC withstanding volt-
age and insulation resistance tests. Measured values and measurement results can
also be read back by remote control. The GPIB and RS-232C interfaces provided as
a standard feature smoothly interface the tester with a PC, sequencer, and other
devices.

Flexible control function realized by a high-voltage scanner
When combined with the optional high-voltage scanner TOS9220 (5 k

DC), the tester can test multiple points in withstanding voltage and insulation
resistance tests. Using the tester panel, each channel can be set to a HI/LO/OPEN
voltage. One scanner can operate up to four channels. Up to four scanners can be
connected to the tester, enabling the simultaneous operation of a total of 16 chan-
nels. The TOS9221 is equipped with a function for detecting connections between
the high-voltage test leadwire and the DUT, thus ensuring highly reliable testing.
