Filter and Last Digit Roundup
Press the OK button 5 times to access the filter time constant, which is expressed
in seconds. You can use the filter to improve your display stability with fluctuating
input signals. Use the UP and DOWN buttons to select a time constant in the
range 0 to 5 seconds. Bigger time constants give more stability but slower
response. Press OK when selected.
The Time constant of this digital filter is very similar to the time constant of an RC filter where
T=RC . The time constant is the time it takes for the display to reach 63 % of its final reading value,
after a step change on the input. You can see that if you select a 1 second filter time, it will take
several seconds for the meter to reach its final value. To give improved response to large step
changes, we momentarily cancel the filter action for stable input step changes of over 64 counts,
and then re-apply the filter to maintain stability.
Another function which can give you a more stable display, with less flicker is
the LAST DIGIT ROUNDUP.
After the filter setting, the display will show LSt and a number. This number sets
the increments by which the meter will change its reading.
