Operating Instructions
5. Calibration
5.1. The operating temperature of the device is pre-calibrated at the factory (the calibration
coefficient is 1.00) which is measured by an external sensor installed in the heating block.
5.2. To enter the calibration coefficient, hold the
TIME-RUN/STOP
key (Fig. 3/5) for more than 8
sec to activate calibration mode. The calibration coefficient will be shown on the display (Fig.
5/1).
5.3. Set 1.000 value using
the ▲ and ▼ keys (Fig. 3/3) as shown on Fig. 5/1 to restore the factory
settings.
5.4. Press the
RPM-RUN/STOP
key once to exit the calibration mode.
Calibration procedure
5.5. Install an independent temperature sensor (thermometer 0.5 C accuracy) into the tubes, placed
into the block, or directly into the heating block special sensor socket.
5.6. Set the required temperature in operation mode (e.g. 40°C).
5.7. After the unit reaches the set temperature (when the set and actual temperature readings are equal)
leave the unit for 30 min for thermal stabilization.
5.8. Let us assume that the reading of the independent temperature
sensor is 39°C, but the display’s
actual temperature is 40 °C (Fig.4). Then it is necessary to add 1°C correction.

5.9. Hold down the
TIME-RUN/STOP
key (Fig. 3/5) for more than 8 sec. to activate calibration
mode. The following parameters will be shown on the display (Fig. 5)
