List source and measurement functions separately
Give the model, serial number and the functions used in the workshop. For thermocouple simulation, list the letter types and requested temperature points. For RTD simulation, give the sensor designation and the two-, three- or four-wire arrangement used with your instruments. Say whether the quotation also needs measurement mode, resistance or millivolt functions.
A specification sheet may list many combinations that your plant never uses. Mark the combinations that affect your actual checks, with the required limits, so a quotation can cover them explicitly.
Include the connection details
Tell us which leads, connectors and detachable modules normally travel with the calibrator. For thermocouple work, include the reference-junction setting used in the procedure. If your records contain a separate check of junction compensation, send that requirement along with the main temperature points.
An electrical simulator represents a sensor signal. It does not heat or cool a probe, so a result for the simulator does not establish the performance of the temperature sensor used in the plant. If both are due, list them as separate assets in the same enquiry.
Keep the maintenance kit complete
Describe intermittent outputs, damaged connectors or a display that will not settle before sending the unit. RTS can review the reported fault and requested calibration together, then confirm which work can be accepted.
Give the release dates and return deadline when asking for a quotation. If the kit is shared between shifts, confirm who will hand it over. For a national instrument list, identify each plant and its accessories so the correct kit goes back to the correct workshop.
Liquid nitrogen comparators
A liquid nitrogen comparator enquiry should identify the apparatus, reference sensor, pressure information and immersion arrangement used in the laboratory. State whether the request is for comparison of customer probes or evaluation of the comparator itself. Cryogenic work needs a specific capability and method review. The presence of a temperature-calibrator page or an ordinary thermal scope entry should not be taken as acceptance of this reference system.
