If the power supply responds correctly, the microcomputer, associated circuits and software are almost certainly functioning
properly.
The most common cause of failure of the power supply to respond to commands sent from the controller is typing errors. To
determine if the power supply has detected an error, send string:
and address the power supply to talk. The response should be:
where x is a decimal digit from 0 to 8. See Table 3-10 for a description of error codes. If the power supply still fails to
respond, check that you are using the appropriate format for sending GP-IB commands from your controller. Check that the
GP-IB address switches on the rear panel of the power supply are set for the address being used. Substitute another GP-IB
instrument for the suspect power supply to determine that a fault exists in the power supply and not in the controller,
interface, or cables.
The following steps check the CV and CC loops and the OVP circuit. Remember that measured responses
(VOUT,IOUT,OVP) may vary within specified tolerances from the expected response.
a. To check the CV loop, send string:
and wait one second for power supply to settle. Send string:
and address the power supply to talk. The response should be:
indicating that the power supply is in the CV mode. Send string:
and address the power supply to talk. The response should be;
b. To check the OVP circuit, send string:
