Reducing the Effect of the Noise (FILTER)
4.3 Reducing the Effect of the Noise
(FILTER)
WARNING
To avoid electric shock or other personal injury, select
the appropriate passband setting when measuring the
AC voltage. If an inappropriate frequency is selected, the
measured value displayed will not be correct.
As the effect of high-frequency noise can be reduced with the low
pass lter (digital lter), this function can be used when measuring
the fundamental frequency (AC voltage measurement) on the
secondary side of the inverter.
This function can be used when measuring the AC voltage, AC/DC
voltage automatic judgment, AC current, and clamp AC current. The
passband setting for the low pass lter can be selected.

Press .
(Current FILTER setting is displayed.)
Each time
is pressed while the
current FILTER setting is displayed, the
passband setting is changed.
[OFF]→[100Hz]→[500Hz]→[OFF]
• When the desired passband setting is displayed for 2 seconds, the
setting is applied and then the measurement display reappears.
• If the FILTER setting is changed, the relative value function
(REL) will be canceled.
