NOTE：
1. In the multi-channel state, the output port of the hipot tester has the original function and it can be
used as a common terminal.
2. Multi-channel output port connection is set by the user. Pay special attention when using: Do not
connect extra high voltage wiring to avoid danger.
3. Using the MF interface to achieve TH90010 online test.
4. Enable CK function, contact testing can be achieved with the test line. In CK, you need to set the
channel for detection, one for high voltage and one for test terminal.
4.6 Structure and Use of HANDLER and SIGNAL Interface Circuit
4.6.1 Control interface theory
Interior theory of HANDLER and SIGNAL interface. See picture below:
4.5.1: Structure and timing sequence of HANDLER and SIGNAL interface
Instruction:
1. HANDLER interface: START, STOP and COM signals makes up remote input control. It is valid in
closing of switching input.
2. HANDLER interface: TEST, PASS and FAIL signals makes up remote output control. It is valid in
closing of switching output. TEST can be used as the starting signal of high voltage or as the pulse
signal when the instrument is in working order.
3. SIGNAL interface is mainly used as the selection signal (INTLOCK) of the instrument when
providing on-line testing of several instruments. The signal defaults to short circuit in one machine.
It is forbidden to start high voltage output of the instrument when in open circuit.
