Insulation resistance test 0.050kV to 1.500kV (resolution of 1V) /
0.1MΩ to 10.0GΩ (Max. rated current of ST9201/S is 10mA, ST9201B
is 5mA)
Insulation resistance test range:
When the voltage is less than 500V: 0.1MΩ to 1GΩ with accuracy of ±[10% of
r5 digits].
When the voltage is greater than 500V: 0.1MΩ to 1GΩ with accuracy of [5% of
r5 digits], 1GΩ to 10GΩ with accuracy of [10% of r5 digits],
10GΩ to 50GΩ with accuracy of [5% of r5 digits].
■
Open and short detection
Before starting high voltage test, make sure that the measured pieces are
reliably connected and high voltage test is safe by ensuring a certain minimum
current is flowing (to detect failed contact) and the current is not excessive (to
detect a short).
■
Programmable by RS-232C and (optional) GPIB interface
Except power switch, key lock and execution (auto), other functions can be
controlled remotely. In DC withstanding voltage test, AC withstanding voltage
test and insulation resistance test, judge and time can be controlled remotely.
The test result can also be read via remote control. GPIB and RS-232C interface
provide stable and unified standard test interfaces for PC or other devices.
■
PLC and HANDLER interfaces bring convenience for the connection
and control.
PLC and HANDLER interfaces can input START, STOP and INTERLOCK signals and
output TEST, PASS and FAIL signals. Connecting with a footswitch, they can
construct a foot-control device; while connecting with simple test fixtures, they
can realize safety interlock, air controls, test indication, etc.
■
USB interface for backup
Through the USB interface equipped by all testers, tester programmed test
programmes and customer’s measuring file can be saved to or recalled from an
external U disk, which is convenient to set, use and file a batch of testers.
■
High voltage scanner can realize the control function flexibly
ST9201S have internal multi-channels, in withstanding voltage test and
insulation resistance, it can control 8 channels to test 8 points. Each channel can
be connected to HI/LO/OPEN voltage. ST9201 series can be connected with
ST9121 multi-channels scanner with 8 channels. ST9201 series can be 2
