Separate the symptom from the comparison
State whether the unit will not power on, has an unreadable display, reports an error or simply disagrees with another instrument. If it disagrees, identify the other instrument and the surface being measured. Record the target dimensions, approximate distance and both readings. A contact probe and an infrared unit may be observing different parts of the same object.
Give the emissivity setting used, or say that it is fixed. For a line-mounted instrument, note any window, protective lens or purge arrangement in the optical path. Include the model number so the team can check the intended field of view and configuration.
Keep the incident history
Mention a drop, liquid exposure, damaged lens, battery problem or unexpected heat exposure before the fault appeared. Send a photograph of visible damage without opening the housing. If a cleaning or repair attempt has already been made, record what was done. The assessment needs the instrument's present condition and the sequence leading to it.
Some handheld models also accept a contact probe. Identify whether that channel works and which accessory was connected, but keep its reported result separate from the infrared measurement.
Review the repair options before approval
RTS will review the model, symptoms and available service route before confirming an estimate. Identify who can approve the work. Replacement of an optical or electronic assembly may depend on manufacturer support; a repair enquiry does not assume those parts are available. Ask for the proposed repair and return checks to be stated separately.
If the instrument belongs to a shared maintenance kit, retain its case label and asset number. List the accessories sent so a repaired or replacement unit can be matched to the correct kit.
Check the reading after repair
A working display and aiming laser do not establish the temperature result. Give the points and measurement arrangement needed for calibration after the work. CC-4643 lists IR thermometer comparison from 50 to 500 °C at emissivity 0.95 for permanent and site facilities. Confirm the relevant entry and setup for the returned model; different settings or a wider range require separate review.
Send it with the working details
Include the return contact, plant town and required date with the fault notes. For a shared kit at IMT Sohna, add the plot and receiving department. Agree the destination before arranging dispatch from any Indian location.
