Appropriate use

The calibration sources, type IRC 45 up to IRC 150, are instruments for inspection of the meas-
urement accuracy of pyrometers (radiation thermometers) at fixed temperature values. The highly
accurate control ensures constant and stable heating of the large emitter surface with high
temperature uniformity with a maximum deviation of 0.2°C. In combination with the high emissivity
at 98% of the emitter surface, the exact verification of pyrometers with larger spot sizes is achiev-
able. The compact dimensions also enable the checking of fixed installed pyrometers at the
measuring location.

Scope of delivery

Calibration source (IRC 45, 70, 75, 95, 100, 110, 120, 140 or 150), stand, power supply 230 V AC
 24 V DC, user manual, works certificate (option: Instrument packed in carrying bag).

Electrical connection

The calibration source has to be connected with the provided
power supply. After switching on the heating-up period starts
automatically. The built-in status LED indicates the operating
status of the calibration source:

Inspection of pyrometers

The unit must be connected to the power supply for a minimum of 20 minutes before checking the
pyrometer. Additionally the pyrometer's emissivity should be adjusted to 98%.

Measuring setup

Note: - Before checking a pyrometer, please ensure the lens is clean. If necessary
the lens can be cleaned with compressed air, which is dry and free of oil or
with a soft, dry cloth such as that used to clean camera lenses.
- Avoid air flow to keep the surface temperature uniformly.
- The temperature of the calibration source has to be minimum 10°C above
the ambient temperature to ensure a faultless control function.
