strain quantity converted value
can be displayed by moving the decimal
point. However, not all digits in display are guaranteed due to the
stability or accuracy, etc.
■ Initial
Setting
Turn ② POWER on while holding both ⑬ SELECT button and ⑦ ↑ key
simultaneously, and keep holding both keys until the measurement value
appears. The unit is then initialized to the user unit of 1.000ｍV/V and the
displayed value of 2000.

during
measurement
■ OVER
Description：Displayed value exceeds the limit of 9999
Countermeasure：If in user unit mode, adjust the maximum digits or the
coefficient so that the expected maximum measurement value fits in 9999.
■ OFF OVER
Description：Input value exceeds the offset adjustable range.
Countermeasure：Refer to Zero Adjustment in the back of the material and
adjust the bridge balance to the level smaller than ±10000×10
−６
strain.

AD
+OVER/‑OVER
Description：The input level from sensor exceeds ±20000×10
−６
strain.
Countermeasure：Open wire or disconnection of sensor or sensor cable is
considered. Make a correction.

times),
data storage life (10 years), setting, internal process. PRM ERR is an error
during setting and the others do not occur during normal operation. In case
of an error, turn off the power then turn it back on. If the error continues,
contact our sales department or distributor.
