2.3 How to Set Calibration Value (CAL) (Entering voltage)
To change the unit from mV to µ

and µ

to mV, depress calibration value setting knob
⑫
(See
Figure 2-5) for one second or longer. Then, the indication of LED changes (e.g., fromµ

to mV). You
can change the unit by depressing the calibration value setting knob
⑫
for one second or longer
when setting the value of each digit. The settable values are as follows.

Calibration value setting
E.g. When changing the CAL value from 2000µ

to 80.25 mV (See Figure 2-6)

As soon as the fourth digit blinks,
decimal number digit starts blinking.
The unit of LED ⑬ changes from
µ

to mV. Turn ⑫ and set the value
to 8, and then press ⑫.
A value of 2 is illuminated on the
second digit, and then the first digit
blinks. Turn
⑫
to set to 5, and
after that Press
⑫
.
All digits illuminates,
and the setting is completed
after 80.05 is indicated.
A value of 8 is illuminated on
the forth digit and also the
third digit blinks. As the third
digit value cannot changed
(staying to be 0), press
⑫
.
A value of 0 is illuminated on the
third digit, and then the second
digit blinks. Turn
⑫
to set 2,
and after that press
⑫
.
Press calibration value setting
knob
⑫
for one second or
longer.
