TC Temperature Calibrators | 37
1. Select the first set point temperature.
2. The controller regulates the dry block or micro bath to the required temperature.
3. Wait until the temperature has been reached and is sufficiently stable.
4. Verify that the temperature output measurement of the DUT is stable.
5. Record the reference temperature of the calibrator and the temperature output
measurement of the DUT.
6. Select the next set point temperature and repeat from step
2.
6.2.3 Canceling the Testing
If the testing has to be canceled, the calibrator must be brought to a safe operational state.
1. Set the set point temperature to a low value, e.g. room temperature.
Note:
Do not leave the calibrator unattended at high temperatures. See Section
2. Wait until the calibrator has cooled down sufficiently.
6.2.4 After the Testing
1. Allow the calibrator to cool to room temperature. See Section
2. If necessary, drain the micro bath or tub insert with the syringe.
3. Clean the calibrator. See Section
8.3.
7. Troubleshooting
Refer to Table
6 for trouble shooting guide.
PREVENT FAILURE
Never open the calibrator. Critical parts or
components may be damaged. Return the calibrator to Druck.
