measurement, they can be cleared by the SYSTEM interface. The specific steps are as follows:
1.
Set the current test conditions on the SETUP interface.
2.
Select the OFFSET item in the SYSTEM screen and set it to ON.
3.
Pressing GET will automatically start the high voltage test and zero the current test value.
4.
If the customer does not set the test time, then the test can be stopped with the STOP
button.
Note:
Do not connect the product to the test terminal during GET. Clearing the product does not
improve the actual test range of the instrument.

SCAN multi-cell multi-channel scanning controller structure and use
The structure of the ST90101/A controller is the high voltage relay matrix. The withstand voltage
tester can directly control the matrix to realize the connection between the controller output and the
output of the withstand voltage tester.
The ST90101 controller has 8 sets of test unit inputs, each of which corresponds to 4 scan output
ports.
The ST90101A controller has 4 sets of test unit inputs, each of which corresponds to 4 scan output
ports.
The ST9010/A withstand voltage meter can control up to 4 controllers, enabling 4*4=16 scan ports
per test unit.
