  • Page 18: Temperature Calibration Check

    6.1 TEMPERATURE CALIBRATION CHECK The CH/P temperature controller has been calibrated prior to shipment of the unit and should not require recalibration for most laboratory applications. However, a periodic check of the temperature control calibration is recommended as a matter of routine maintenance. A check of temperature calibration is especially advisable when the ambient temperature is less than 19 degrees C (66 degrees F) or more than 29 degrees C (84 degrees F).
