Noise Countermeasures
Connect the ground wire in the following method if the measured values are unstable due to noise.
Connect the ZR-RX70's GND to ground.
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 ZR-RX70’s chassis GND.
Use a short, thick lead to connect the chassis GND of the measurement object to the ZR-RX70’s chassis GND.
It will become even more effective if the ground potentials are the same.
In the AMP Settings menu, set Filter to any setting other than OFF.
