Useful functions (calibration offset function)
Using the calibration offset
function
Calibration offset function compensates any differences
between the target temperature in the bath and the control
temperature of the controller (sensor temperature.) The
function can compensate in parallel to either plus or minus
side for the whole temperature band of the unit.
The lock can be set or released with the SUB MENU keys.
The temperature is set at “0” on shipping from the
factory.

①
Start operation at the target set temperature and
confirm the temperature in the bath with a temperature
recorder after temperature has stabilized.
②
Confirm the difference between the set temperature
and that in the bath.
③
Press the TIMER key (SUB MENU key) long to enter
the sub menu mode.
Press the TIMER key (SUB MENU key) several times
to select the characters cAL
that indicate the
calibration offset function.
④
Enter the difference between the set temperature and
the temperature in the bath using the
▼ ▲
keys and
press the TIMER key (SUB MENU key) long to exit the
sub menu mode.
(When you want to set the key lock
function, proceed to character selection process for the
key lock function without pressing the TIMER key
(SUB MENU key) long.

* You can set either of + or – side for the offset compensation temperature.
When compensation is set for the – side, the MEASURED TEMP. display decreases by the
compensation temperature while the temperature in the bath increases by the same amount.
When compensation is set for the + side, the MEASURED TEMP. display increases by the
compensation temperature while the temperature in the bath decreases by the same amount.
* Since too large a compensation value may result in larger difference between the actual and
indicated temperatures and may present a danger, consult our nearest sales office before
entering a large compensation value.
* The device has, in addition to the calibration offset function, the two-point compensation function
that adjusts offset for the lower temperature range and higher temperature range, for which
adjustment temperatures have been input on shipping from the factory.
* Consult the nearest sales office before attempting validation work for the temperature adjusting
device.
