Low-pass filter (LPF)
This is a low-pass filter for canceling unnecessary noise contents by filtering input signals from
UTM
Ⅱ
. A cut-off frequency of a low-pass filter can be selected from 10Hz to 30kHz. Frequency
contents higher than the set frequencies will be attenuated. The higher the cut-off frequency, the
quicker the response to input signals, but noise contents may also be displayed.
<Setting range>
10, 30, 100, 300, 1k, 3k, 10k, 30k [Hz]

Moving average (AVERAGE)
This filter takes the moving averages of the A/D converted data and reduces fluctuation of indicated
values. The number of times to perform the moving average can be set up to 999 times. The higher the
number of times, the more stable the indicated values, but the response will be slower. The lower the
number of times, the quicker the response, but indicated values will be more likely to fluctuate.
<Setting range>
0 to 999

Upper limit (UPPER LIM.)/
lower limit (LOWER LIM.)
This function sets the upper limit and lower limit, and lights on the HI status display when an
indicated value exceeds the upper limit, and LO status display when an indicated value falls below
the lower limit.
<Setting range>
-9999 to 9999
