French Calibration Pulser Supply

Trouble Shooting

These supplies are relatively simple and basic trouble-shooting strategies should be used.

Here are some hints of things that can cause problems.

• The supplies use remote sensing at the output connector. If the feedback wiring opens then supply will overvoltage and crowbar. The result will be no output voltage and a supply that appears to be broken. Always check that the feedback wiring has continuity back to the supply remote sensing terminals.
• If there is no output voltage check the fuse for that circuit.
• The control power is active as soon as the line cord is plugged in. If the front panel switch is not turn on the supply will indicate an under-voltage trip.
