Record the operating conditions
Provide the make, model, channel ratings and set values. State whether the displayed output and the external reading disagreed, or whether the unit changed into current limit. Mention tracking or remote-sense operation when it was in use, and identify any accessory involved.
Define the checks after assessment
Give the make and model before sending a heavy supply. RTS can review bench suitability, parts availability and whether repair or replacement should be quoted. Request the agreed voltage and current checks separately if the unit must go back onto a controlled test bench.
A fault on one channel or during a programmed sequence
Keep the sequence step or channel designation with the observed symptom. A supply that works at one setting but trips during a stored test needs more context than a note saying “no output”. Include the voltage and current settings, displayed mode and any error message already recorded. State whether the front panel or an external controller was commanding the unit when the problem occurred.
Send existing photographs or logs that preserve an intermittent fault. Do not open the unit or repeat a suspected short circuit to create new evidence. If the estimate proposes replacement, confirm the channel count, output ratings, sense connections and control interface your fixture needs. A similar-looking supply may not fit the same test sequence. Agree who will restore the approved program and review the voltage/current results before the bench returns to use.
Separate the supply from its test fixture
Tell us whether a load fixture belongs to the line or travels with the supply. Keep the channel numbers and asset tags in the same handover note, with the person who will reconnect the accepted unit at its destination.
