6. Settings and Operations Relating to Indicated Values
6-1. Digital Filter
A/D-converted data is moving-averaged to reduce unsteadiness of indicated values by
this function. The number of times of moving average can be selected from the
following. With an increasing number of times of moving average, the display stabilizes
but the response becomes slow.
Setting item: None / 2’ / 4’ / 8’ / 16 ’/ 32’
6-2. Analog Filter
This is a low-pass filter to cancel unnecessary noise components by filtering input
signals from the sensor. The cutoff frequency of the low-pass filter can be selected from
the following. With increasing cutoff frequency, the response becomes fast but noise
components may be displayed in a waveform.
Setting item: 10Hz / 50Hz / 200Hz / 600Hz
6-3. Digital Offset
The digital reference point (zero point of indicated values) is offset by this function. The
value set here is subtracted from the actual indicated value (added if the sign is negative)
for display.
(Displayed indicated value) = (Actual indicated value) - (Digital offset set value)
Setting range: -9999 ~ +9999 (Not including the decimal point.)

If Zero Calibration / DZ is performed with the digital offset set
at "-100," the displayed indicated value becomes "100."
