Describe one channel at a time
Give the output ratings for each channel and the voltage and current combinations used on the bench. Identify any channels that ordinarily run in series, in parallel or in tracking mode. If remote sensing is used at the fixture, describe that connection in the request.
Identify the setting, readback and load
A production test might specify voltage at a stated load. A battery fixture might instead rely on the supply holding a particular current. Give those operating points and say whether you need output, readback or both checked. List a current-limit check separately if it is part of your acceptance procedure.
Readback accuracy and output quality
If the bench software records a programmed setting, include that setting in the point list. If it records the supply's own measured voltage or current, identify the readback instead. A result for one channel cannot be assumed to cover another, even when both channels have the same rating. Name any channels that are excluded from the order.
Ripple, noise and response to a changing load are separate requirements from a steady DC output comparison. Send the relevant acceptance limit and test condition if your product procedure relies on one of these features. An existing plot or procedure extract can help RTS review the request. Agree the measurements and reporting conditions before release so the returned results answer the bench's actual checks.
Plan the bench release
Include the rack identifier and say whether the supply can be removed. When several benches use the same model, list the serial number and channel configuration at each site. Agree which leads, interfaces and external fixtures need to travel.
Battery chargers with measurement indications
A battery charger may show voltage, current and accumulated charge while changing its operating stage. Record the model, selected battery profile and the quantities for which you need results. State whether the output is checked under a specified load or with a particular battery arrangement. Keep charging behaviour and electrical indication accuracy as separate requirements. RTS can review the proposed measurement without treating the charger as an ordinary fixed DC source.
