3.0 - Usage Recommendations
It is of great importance to know the instrument to be calibrated. Infrared
thermometers have characteristics which must be met so that the observed results are
correct, as setting of emissivity (if any), focal length and focus area, e.g. These data are
easily obtained in the thermometer user manual and this observation is needed to
prove the compatibility of thermometers with the calibrator.
To perform the readings, align the pyrometer with the black body cavity
horizontally. Respect the distance from the pyrometer to be calibrated in relation to the
black body cavity to the size of the actual cavity as pyrometer manual. Remember that
the area focused by the pyrometer to be calibrated must be less than or equal to the
black body cavity size in order to not introduce measurement errors.
The external sensor is an optional accessory that may be purchased to increase
the accuracy of temperature indication. This sensor is supplied with the parameters of
the Callendar-Van Dusen that can be configured in the RTD input of T-500PIR
calibrator.
4.0 - Safety Instructions
• Do not leave the place where the calibrator is on without identification and warnings.
• Before turning off the calibrator, return temperature black body cavity for values
close to ambient temperature.
