INPUT FILTER
The tables below show the maximum frequency which can pass through the filter when the sensitivity level is set to 2 V. The
frequency may change according to the sensitivity level.
After turning the filter ON, check that the PL1 and PL2 blink according to the input signals. If they do not, readjust the
sensitivity according to the instructions in the following section.
