(3) Checking (Calibration) of the indicated
value on the recorder (optional)
This recorder can be checked for its
switching function for recording sensors and
temperature indication function regardless
of inside temperature, and can be adjusted.
1) Switching function for recording sensors
By operating the set temperature on the
controller, the temperature recorder
automatically switches the recording sensors,
return air sensor (for frozen and partial frozen
modes) and supply air sensor (for chilled mode)

during transportation.
3. When the power is supplied, the
pen vibrates momentarily and will
return to its original position due to
the recording characteristics, but
this is not a sign of trouble.
