CR Characteristic (Primary) Digital Filter
You can select CR characteristic digital filters in addition to the conventional digital filtering by the
moving-average method alone.
Step response
waveform
- Primary CR filter characteristics are shown.
- Like an analog filter, you can set the cutoff frequency, where the degree of flexibility in cutoff
frequency increases.
The cutoff frequency can be set in the range of 1 to 990Hz.
The cutoff frequency can be set in units of hertz in the range of 1 to 100Hz.
The cutoff frequency can be set in units of 10 hertz in the range of 100 to 990Hz.
- Compared with an analog filter, the individual difference in characteristics is small.
- A high pass filter can also be selected.
When a high pass filter is used ...

When this setting is CR type LPF or CR type HPF, the Digital Filter setting in the operation setting
menu becomes the cutoff frequency setting.

Averaging on Digital Zero
When Digital Zero is executed, an average calculation is made by the time set for Average Time On
Digital Zero, and upon completion of the calculation, the average value is subtracted from the value
indicated at that time. (However, the maximum average time in Digital Zero is 5 sec. In the case of
more than that, processing will be performed by 5 sec.)
