Output Filter Settings –Switch 3
The SGA incorporates a second order (-12dB/oct) low pass filter which can be switched in to improve the
performance and output signal quality in electrically noisy environments.
It can also be used to reduce the effects of high frequency fluctuations in the load or applied force to the load cell.
The cut off frequency of the filter is set by the DIP switch SW3 as illustrated in the table below

** Note:
A SECONDARY low pass filter, with a cut off frequency of 800Hz, can be switched into the SGA input by fitting a
link to JP3 (see Figure 3.2)
Important:
Low pass filtering is switched into operation by setting SW4/6 ‘ON’
↑
and
SW4/7 ‘OFF’
↓
. Reverse these settings to bypass the filter.
It should be noted that either one of these switches MUST be on but not BOTH
