○
The shield cable should be connected to the ground and input connector.
2
○
The cable resistance of the internal cables should be regular.
3
○
It's better to use the shield cable.

○
All wires should be built in the clean environment for the measurement.

(Please avoid using transformer, motors, relay and high voltage cable where
the magnetic field can be easily generated. If it is necessary to use one of
them, please use any structure for the protection.)
○
If you use a long wire, please use a balanced leading line so that you can
6
minimize the noise.
4-6. Notes for Static measurement
You must make sure that the cable resistance between each gauge lead wire is
regular. If it is not, the measurement value can be changed by the surrounding
temperature. Please pay your special attention for this point.
Please carry out the following procedures.
○
You must us 3-line for Quarter Bridge.

○
To minimize the effect by the temperature change, it is ideal to put all the used
2
lead wire in the same wire bunch.
○
To build the precise data when you use a long wire, please do the
3
compensation considering the resistance of lead.
(Example : The thickness, length of the wire and its proper resistance etc)
4-7. Output connection
Output ± 10V can read the voltage output value as in oscilloscope, volt meter and
A/D board as BNC connector.
4-8. Controlling proper sensor voltage
Sometimes when you do the stress analysis, the high proper voltage to the active
gauge might be required. When the proper voltage is high, the output will be big
so that you do not have to amplify too much. But when the high voltage is applied
