This provides the operator with an easy and safe
way to set trip currents and output voltages since
parameters are set without the high voltage
activated.
This assures you that this instrument meets or
exceeds safety requirements to ensure operator
safety.
High Withstand Voltage Tester powers up with the
parameters that were used during the last test to
avoid operator set-up errors.
The easy to follow setup screens ensure that the
operator correctly sets up all test parameters
This makes it possible to limit user access to the
setup screens so that only authorized personnel
with a security code can change test parameters.
The electronic dwell control helps keep test results
consistent by ensuring that the test duration is the
same for each product tested.
The standard 9 pin interfaces provide outputs for
Pass, Fail, and Test in Process. Inputs include
Test, Interlock and Reset.

basic remotes required to configure the High
Withstand Voltage Tester through simple PLC
relay control.
High Withstand Voltage Tester is calibrated
through the front panel keypad. All calibration
information is stored in non-volatile memory This
allows High Withstand Voltage Tester to be
completely calibrated without removing any covers
and exposing the technician to hazardous
voltages.
High Withstand Voltage Tester was designed for
the global market. This feature makes it simple
for the user to select the output frequency in the
AC hipot mode so that products can be tested at
the same frequency they will be used at.
To make High Withstand Voltage Tester usable in
all types of applications, the operator can manually
bring the voltage up or down in 10 volt increments
by simply pressing the up and down arrow keys.
This makes it very easy to adjust the output
