CALIBRATION
Temperature calibration
1.
Press the calibration key (CAL) for approximately 5 seconds.
2.
The left digit of the digital temperature indicator blinks, and the other indicators go out.
3.
Set the present correct temperature with the digit shift key ( ) and numerical value shift key ( ),
then press the enter key (ENT).
4.
The unit automatically reverts to the display mode.
[Example]
If the displayed chamber temperature is 37.0
o
C (set value) and the actual temperature is 36.8
o
C.
1.
Press the calibration key (CAL) for about 5 seconds.
2.
The “3” on the digital temperature indicator blinks, and the other indicators go out.
3.
Adjust the set value to the actual value of 36.8
o
C with the digit shift key ( ) and numerical value
shift key ( ), then press enter key (ENT).
4.
The unit automatically reverts to the display mode.
Note:
It is important to accurately measure the temperature inside the unit when performing temperature
calibration. Particularly, the temperature gauge used must have an accuracy of 0.5 class or better.
The temperature must be measured at several points.
The temperature setting must not change by more than ±1.0
o
C during calibration. If it exceeds this, an
error tone is emitted, the input data is ignored, and the unit reverts to the display mode. Consequently, if
it is necessary to change the temperature by more than 1.0
o
C, perform calibration in several stages over
a period of time.
