special circumstances.
The recorder is optional for HYC-610 only, not available for others.
Calibration of Recorder
The temperature recorder has been accurately adjusted before leaving the factory even if the power
supply is interrupted. If there is a need to be adjusted, perform the following procedures.
1. Let the unit run for at least 2 additional hours after it reaches stable condition,
2. Place a standard thermocouple in the temperature solution bottle filled with 100 ml 10%
glycerol solution. Place the sensor of the temperature recorder into the sensor bottle as well.
3. Place the sensor bottle in the refrigerator for at least 4 hours. Compare the thermocouple
reading and the recorder reading. If there is a discrepancy, press the adjustment button on the
left (1#) or on the right (2#) of the panel to adjust the temperature value of the recorder so that
recorder reading matches the reading of the thermocouple.
Note: The recorder pen will start moving 5 seconds after the button is left out.
