2.15 Noise Countermeasures

Be sure to connect the chassis GND of the object to be measured.

It may become effective by ensuring that the chassis GND wire of the measurement object is
connected to a good ground.

Connect the signal chassis GND and the measurement device chassis ground.

Use a short, thick lead to connect the chassis GND of the measurement object to the GL800’
chassis GND. It will become even more effective if the ground potentials are the same.

The effects of the digital filter function will vary depending on the number of terminal channels and
sampling speed.

If measured values fluctuate due to noise, set the sampling speed to a value which enables the
digital filter function.

See page 3-20 for details.
