Figure 4.5.3 Connection of HANDLER external Circuit
1.
The above picture shows the connection circuit diagram of an external power
source and the indicator lights, the TEST control switch of the instrument
interface MUST be in switch mode.
2.
When the load current is relatively large, use an external power supply. The
TEST control switch of the instrument interface must be in switch mode.
Instrument control contacts can switch a control signal of 220VAC with a
maximum current of 1A.
Note: In external power mode, the TEST control switch of the instrument interface
should be in switch mode, or it will burn the instrument.
