Resolution
(Filter time constant)
Digital filter time constant : for damping the
too fast variations of the signal. 1 to 99
seconds (or OFF). If you notice the "noise" in
the signal, increase this value.
(Display update rate)
Display update rate (0.5 to 6.0 sec).
Zero offset from -200 to +200). (To re-adjust
the measurement for example)
