External control of Hipot tester (Automatic Insulation/Withstanding HiTester 3153)
QTesting won't not stop when I connect the STOP and GND terminals on the external I/O terminals of the 3153. I used the same method for a separate model 3158 and 3159, but they could be controlled without any problem. What could be the cause?
A
Model 3153 has a different external I/O terminal configuration from models 3158 and 3159-02.
To control external start/stop with 3153, please connect between EXT.DCV and ISO.DCV.
Control using the external switch (When the internal power supply is used)
To control the START and STOP signals using a relay or switch, make connections as shown below:
