3−4. Notes on installation and connection
1Installation place
●In case of connection with the instrument, keep strictly to the following items. If
neglected, it may cause an unexpected failure or a damage to the instrument.
DPlease choose the place without a mechanical vibration and a corrosive gas as the place
where this instrument is installed.
Moreover, be careful not to give unnecessary external force to this instrument.
DPlease avoid use in the environment that moisture adheres to this instrument
Moreover, please never pour water directly.
2Connection
DThe connecting cable with the torque transducer must use the cable attached to the torque
transducer.
DPlease separate the cable connected with this instrument as long as possible from the noise
sourse, like a power supply line (motor and inverter) or I/O line for control, etc.
It causes the accuracy decrease (zero change and output voltage change, etc.) by the
influence of the noise when wiring near these lines.
Especially, please separate the cable which connects the torque transducer with this
instrument from these lines by 50 cm or more.

4. Calibration method
4−1. Calibration method of torque
There are two kinds of methods of the torque calibration of this instrument.
1Electrical calibration
The calibration is made electrically by the attached combination inspection data sheet.
2Actual torque transducer
The calibration is made by applying the rated torque to the torque transducer.
4−2. Preparation before adjustment
Supply the power upon confirming if the torque transducer and power supply are connected
correctly. (Refer to the paragraph 3−3.)
Please take the warming−up of about 15−20 minutes to make this instrument work stabilizing
though this instrument becomes a working condition after turning on the power supply.
