4.3 Turning ON/OFF the Input Filter
Explanation
4-6
The following two types of input filters are provided. The filters eliminates noise such as
inverter waveforms and distorted waveforms and allow stable measured values to be
obtained.
Line Filter
This filter is inserted only into the measurement circuit. It eliminates noise
components of the input signal. The cutoff frequency is 500 Hz.
• on: Selecting on and pressing the ENTER key enables the line filter function and
turns ON the LINE indicator.
• oFF: Selecting oFF and pressing the ENTER key disables the line filter function.
The LINE indicator turns OFF.
Frequency Filter
This filter is inserted only into the frequency measurement circuit. The cutoff
frequency is 500 Hz. Since the WT210/230 is making measurements in sync with the
input signal, the frequency of the input signal must be measured correctly.
• on: Selecting on and pressing the ENTER key enables the frequency filter function
and turns ON the FREQ indicator.
• oFF: Selecting oFF and pressing the ENTER key disables the frequency filter
function. The FREQ indicator turns OFF.
Note
You cannot change the input filter ON/OFF setting when integration is started. You must stop
and reset integration to do so.
