5. OPERATION PROCEDURES
Calibration offset
Calibration offset is a function which can correct for any differences discovered between actual liquid
temperature and the temperature displayed on the control panel. Offset function can correct to either
the positive or negative side of the entire unit temperature range.
・
Run unit at desired temperature. Once temperature has risen and stabilized, gauge temperature of
circulating water with a thermograph.
・
Check the difference between the set temperature and the actual liquid temperature.
Example
Actual temperature is lower than temperature reading by 2 °C:
Temperature reading can be calibrated by entering a calibration offset value of -2.0 to compensate
against the actual temperature deficiency of 2 °C.
If the initial temperature reading was 20 °C, it will read 18 °C after offset calibration, and be brought
into agreement with actual temperature.
1. Enter user setting
Turn power switch
ON (|) and press
key for three
seconds while temperature reading is on the screen.
Unit enters user setting.
2. Change offset value
1. Select "CAL" using the
∧∨
keys.
Temperature display: "CAL" flashes.
2. Press
key
Temperature display: Current set value flashes.
3. Enter a value that brings set temperature and
circulating water temperature into agreement, using
the
∧∨
keys.
4. Press
key to finalize.
Temperature display: Set value is shown for about one
second.
After completion, the screen returns to step 1.
3. Exit user setting
After completing the setting, press and hold key
for
two seconds. Display reverts to initial screen and shows
temperature reading.
Press 2 sec.
Press 3 sec.
