Optional Accessories
This recorder has been calibrated at the factory. It retains the temperature accuracy and calibration even when there is a power supply interruption. Should there be a need to recalibrate the recorder, please follow the procedures below.
a)Let the unit run continuously until it reaches a stable condition. The recorder has registered temperature for at least two hours.
b)Place a standard thermocouple in a 100 ml container filled with 10% glycerin solution. Place the container and the temperature recorder sensor in the unit. Do not place the recorder sensor in contact with any liquid.
c)After four hours of soak time at the stable freezer temperature, the container temperature should match the freezer temperature. Then compare the thermocouple reading with the temperature recorder reading. If there is a discrepancy, use the button (#1) or the button (#2) on the recorder to move the pen on the chart to reflect the correct temperature.
Note: The ink pen will operate 5 seconds after the button is released.
Caution: The temperature recorder is preset during production, so resetting of the temperature recorder is not recommended unless absolutely necessary.
