Recommended calibration procedure
The recommended process for both first and second calibrations is as follows:
1. Charge the dosemeter battery using the CHR22 charger in the same vicinity as
the MODEL 22R Reader.
2. Once fully charged, remove the dosemeter from the CHR22 charger for a period
of roughly 5 to 10 minutes.
3. Calibrate the dosemeter using the MODEL 22R Reader.
4. Carry out the measurement.
5. Stop the dosemeter.
6. Charge the dosemeter before carrying out the second calibration and
downloading the measurement data.
If the recommended battery recharge cannot be conducted after a long measurement
then leave the dosemeter in the same environment as the Reader for at least 30
minutes so that both units are stable and matched for environmental conditions.
