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.

PROGRAM
① Start operation at the target set temperature and confirm the
temperature in the bath (sample temperature) with a temperature
recorder after temperature has stabilized.
② Confirm the difference between the set temperature and that in
the bath (sample temperature).
③ Press the SUB MENU key, select the character cAL that
indicates calibration offset using the ▼▲ keys and press the
ENTER key.
④ Input the difference between the set temperature and that in the
bath using the ▼▲ keys and press the ENTER key to complete
setting.
* You can set either of + or – side up to +99℃ and -99℃
respectively 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.
