Calibration
The instrument is pre-calibrated at the factory (calibrating coefficient - 1.00) for operation with
measured temperature from sensor installed in the thermoblock.
To enter the calibration coefficient, hold TIMER-START/STOP key (Fig. 6/5) pressed for
more than 8 sec to activate calibration mode. Display will show the calibration coefficient as
shown on fig.8/1.
To restore the factory settings with the help of Temp. “▲” and “▼“ keys (Fig. 6/3) set 1.000
value as shown on fig.8/1.
To exit calibration mode press SHAKER-START/STOP key (Fig. 6/4) once.

Calibration procedure
To perform calibration install independent sensor (accuracy 0.5°C) inside tubes into the block
sockets or right in thermoblock special sensor socket.
Set the necessary temperature (e.g. 40°C).
After the unit reaches the set temperature (when the set and current temperature readings
becomes the same) it is necessary to leave unit for 30 min for thermal stabilization.
Let us assume that the readings of independent sensor is 39 °C, but the display’s actual
temperature is 40 °C (Fig.7), it is necessary to add correction 1 °C.

Hold TIMER-START/STOP key (Fig. 6/5) pressed for more than 8 sec. to activate calibration
mode. Display will show the following parameters as shown on fig.8.
