What needs to appear on the test record?
For a pressure transmitter, give the tag, pressure units, configured limits and electrical output. If the commissioning sheet also calls for the displayed value at the receiving panel, identify that channel. RTS can then quote a transmitter calibration or review the installed loop with the engineer who will witness the check.
Closing a contractor's test sheet
When a gauge has changed hands halfway through a pump test, the instrument list can show the same pump tag against two different gauge serial numbers. Ask the supervisor for the changeover time and which serial number was in service during each part of the job. Keep that distinction on the purchase order as well as on the inspection record.
A transmitter connected to a temporary panel may be moved again after commissioning. Record the panel channel and current scaling as found on the day of the check. The plant can then tell which part of the record still applies after installation changes.
The test kit that leaves with the contractor
For a portable current calibrator, state whether the crew uses it to supply current, read current or both. Send the next mobilisation date and the PIN where the case can be collected. A kit hired from an IMT Faridabad workshop may have to return to that workshop even though the commissioning record belongs in Orvakal.
