Describe the output that the bench was using
Record the selected voltage and frequency, connected load and any current-limit indication from the last test. For a multi-phase source, identify the affected phase or channel. If the failure occurs during a programmed sequence, include the step number and saved error log. Mark whether the source was under front-panel control or commanded by bench software. Those details give the assessment a repeatable starting description.
Identify a variable transformer separately
For equipment described as a Variac or variable AC supply, send the nameplate and control arrangement rather than applying the settings of a programmable source. Describe uneven adjustment, a damaged terminal or an abnormal sound already observed. Include the enclosure and meter identities when these form one assembly. Do not treat the transformer, external indicator and load fixture as interchangeable parts of the quotation.
Record the boundary of the proposed work
Provide the rack or bench identifier and say which interfaces, external sensing leads or output fixtures can travel. A problem that appears only with one product fixture should be described that way; it is not yet a confirmed source fault. Ask RTS to state the equipment included in the assessment and to obtain approval before component replacement, configuration changes or further work on the test station.
Decide what the returning source must demonstrate
List the voltage, frequency, load and readback combinations your procedure needs after repair. Steady output accuracy, waveform behaviour and a programmed transient are separate checks. CC-4643 lists AC voltage and current entries at 50 Hz; that does not cover every frequency or waveform a source can produce. Agree the proposed calibration and other tests against the bench procedure before accepting the repair estimate.
Arrange removal and return
Give the unit's approximate weight, case count and available release window. The plant's electrical team should arrange disconnection and reinstatement at the test bench. For an IMT Manesar bench, include the equipment owner and goods-receiving gate. For other locations, confirm the destination and transport arrangements with RTS before sending the source.
