Confirming Interlock Circuit
Perform the following procedure to confirm that the interlock circuit works
correctly.
1. Connect an interlock connection cable between the Intlk terminal and the
interlock terminal of an instrument such as the Keysight 4155/4156 and E5270.
2. Close the lid of the 16442B.
3. Set all channel output to 0 V.
4. Confirm that the High Voltage LED is turning off.
5. Change a channel output to greater than 42 V. The High Voltage LED has to turn
on.
6. Open the lid of the 16442B. The High Voltage LED has to turn off.
Opening the lid will make the instrument cause an error or change voltage to
0 V.
