Calibration Offset Function
Set Calibration Offset
The offset function works to correct discrepancies found between the
bath temperature reading, as seen on the display and actual bath
temperature, as taken manually, by matching temperature setting to the
actual temperature. Enter a positive difference value when the bath
temperature is found to be higher than the control panel reading. Enter
a negative difference value when bath temperature is found to be lower
than the control panel reading. Use the MAINTENANCE menu to set
or cancel this function.
The factory default calibration offset value is
[0]
①
Start a constant temperature operation at any temperature. When
temperature stabilizes, measure bath temperature using a
temperature recorder or other precision thermometer.
②
If control panel temperature reading and manually taken temperature
differ, follow the steps below:
③
Press and hold TIMER for about four seconds, then press it
repeatedly until [cAL] is displayed.
④
The screen displays [cAL] and correction temperature. Enter the
difference (negative or positive) using
△▽
while digits are flashing.
This completes the setting.
If a negative value is entered, bath temperature rises according to the
value entered. If a positive value is entered, bath temperature
decreases by the value entered.
Example:
A temperature reading of 60°C and an actual temperature of 58°C
would call for an offset value of -2, bringing the actual temperature up
2°C, to 60°C.
