Install each cable while turned off the power supply. Might it get an electric shock, and this instrument be damaged when working with the
power supply enters.

Confirm the indication of the power supply voltage of the instrument and the specifications are corresponding to the supplied power supply
before turning on the power supply. Consult with MINEBEA when not matching. There is danger of causing damage and the electric shock of
this instrument when using it like the uncertainty.

Groundline should be connected securely. When groundline is not connected, it may cause a malfunction of the instrument or el ectric shock to
the operator

Before this instrument is newly used, or when the strain gage applied transuducer is exchanged with a new one, please execute the calibration.
If not calibrating, it may cause not obtaining the correct measurement result, or a malfunction in the instrument and there i s a possibility of the
damage of peripherals. Moreover, there is a similar possibility that the result is incorrect even if the calibration has been already made. Please
take the calibration again.

Please confirm connecting wires is correctly executed when you use this instrument. If it is not connected correctly, it may cause the
malfunctions on the instrument, and the damage to the peripheral equipments or even worse serious accidents.

CautionIt causes not obtaining a correct measurement result, and the malfunction when the setting change is carelessly executed while
measuring it with this instrument and there is a possibility of the damage of peripherals.。
