Select "calibration LOCK".
Press the
key twice.
Switch the “calibration LOCK” to OFF (0) using
the
keys, and confirm it with
the
key.

Excitation voltage
The excitation voltage to supply to a strain gauge type sensor is selected.
■
Excitation voltage setting method
1.
Select setting mode 3.
→
(twice)
2.
Select "excitation voltage".
Press the
key eight times.
Set the excitation voltage using the
keys, and confirm it with the
key.
3.
Press the
key to return to the indicated value display.
Caution
A strain gauge type sensor to be connected to the F325 must always have a maxi-
mum excitation voltage value higher than the set bridge voltage.
In cases where the excitation voltage of the F325 is larger than the maximum excita-
tion voltage value of the sensor, the sensor might generate heat or break down.
