Describe the reference source
Send the manufacturer, model and serial number, together with the manual and last certificate if available. State whether the source has a cavity or a flat target, its aperture dimensions and the temperatures normally used. Include any external controller or reference probe that forms part of the working arrangement.
Please mention surface damage, changes to the target coating or a replacement insert. A photograph can help establish the configuration, but avoid cleaning or altering a reference surface simply to prepare it for a photograph. Follow the manufacturer’s handling instructions.
Explain the reference you need
A displayed temperature and the radiance temperature presented to an infrared instrument are different parts of the measurement. Tell us what your procedure requires the certificate to report. Include the source specification, emissivity information supplied by its manufacturer and the points used for routine checks.
Target size, measuring distance and the receiving instrument’s optics influence a comparison. State whether the source supports a spot thermometer, an installed pyrometer or a thermal camera. RTS will review the required reference arrangement and job scope before accepting the source. Do not assume a general temperature check covers every infrared application.
Arrange transport around the checking schedule
Give the date of the next round of infrared instrument checks and say whether another reference is available while the source is away. Let the source reach the condition required by its manual before packing, and ask RTS to confirm the receiving and packing arrangements.
For enquiries from other Indian plants, list the source and accessories under one dispatch reference. Keep its previous certificate available so the requested work and earlier results can be compared.
