2.2 Appropriate use

The calibration sources, t

ype 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.

2.3 Scope of delivery

Calibration source (IRC 4

5, 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).

3 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:

green: warm-up

orange: ready for operation

red: overheating

4 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%.

4.1 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.
