Notice
Notice
Be sure to check that the power supply is off in connecting each cable. If the work is done while the power is on, there may have the case that
electric shock to the operator or even may have damage to the instrument.
Before supplying the power, check that the indication of power supply voltage and its specifications for the instrument and the power going to
supply should be the same.
If they are not equal, contact with Minebea.
If you use the instrument without checking it, that may cause a damage in the instrument or electric shock to the operator.
An earth wire should be grounded securely.
When an earth wire is not connected, it may cause a malfunction of the instrument or electric shock to the operator.
Before using a new instrument or exchanging the strain gage applied transducer for a new one, be sure to make calibration. If calibration will not
be made, the correct measuring results may not be obtained nor which may cause malfunction in the instrument and there may exist damage in
peripheral equipments.
Even though calibration has been made, there may occur the similar case when the results are not correct, so make calibration again.
In case of using the instrument, check that the connections are executed properly. If not connected properly, the correct measured result will
not be obtained, nor may it cause malfunctions of the instrument, damage to the peripheral equipments or even more serious accidents.
When change of setting is made carelessly on the instrument during measurement, correct measured results may not be obtained and it may
cause malfunction in the instrument and even have the possibility of damage in peripheral instruments.
Do not shock the instrument such as throwing something on it.
If neglected, it may cause destruction of the parts and damage to the electrical circuits.
