CALIBRATION
The temperature can be calibrated as necessary. CARON recommends an annual
calibration check.
Place the reference instrument’s temperature sensor in the tank or
circulating loop at the desired control location. Before making a calibration adjustment,
allow the circulator to stabilize.
The calibration offset is adjustable from -10.0°C to 10.0°C. The default is 0.0°C. To
enter a calibration offset:
1) Press the key four times from the main menu, “cAL" is displayed briefly
2) Press the to increase / decrease the calibration offset (hold for scroll)
3) Press the key to save the calibration offset
4) Press the key once to return to the main menu
Temperature calibration example:
If the circulator temperature display reads 40.0°C and the calibrated independent
sensor shows 40.3°C, set the calibration offset to 0.3°C. If the calibrated independent
sensor shows 39.6°C, then the entered offset should be negative. In this example the
required offset would be -0.4°C.
