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.
Measurement object
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 ZR-RX45' chassis GND.
It will become even more effective if the ground potentials are the same.
Measurement device chassis
Noise countermeasures
If measured values fluctuate due to extraneous noise, conduct the following countermeasures.
(Results may differ according to noise type.)
Ex 1 : Connect the ZR-RX45's GND to ground.
Ex 2 : Connect ZR-RX45's GND to measurement object's GND.
Ex 3 : In the AMP settings menu, set filter to any setting other than "OFF".
Ex 4 : Operate ZR-RX45 with batteries (Option: ZR-XRB1).
Ex 5 : Set the sampling interval which enables ZR-RX45's digital filter.
Use the "OTHER" menu to set the commercial power frequency you use.
