DISPLAY FUNCTIONS


Max / Mini recording
In order to review & trace the drifting PV, the meters
will keep the values of maximum and minimum in [ user
level] during power on. User can reset the values by
[ Mrst] in [ user level]. And it'll record new maximum
and minimum value immediately after reset.

Low Cut [lOcut]
Settable range from -19999~+29999 digits
Usually caused by interference, system factors or natural
phenomena when there are small values near zero point,
this feature displays zero。
If[lOcut] Setting is positive, it means that the displayed
value in [lOcut] settingsare within the absolute value is
displayed as [lOsc] settings；
I displayed I ≤ [lOcut] settings，
and displayed all are [ lOsc] settings。

Low Cut is set for 0.50, if the PV is
from -0.50~+0.50, that display will be 0.
If [lOcut] setting show that the value is negative
in [lOcut] The following settings are displayed

The meter's sampling is 15cycle/sec；[ Mavg] set to

the display update with 15 times/sec，
In the first updated display value will be same as
average function. In the next updated display value,
the function will get the new fourth sample (sample 4)
then throw away the first sample (sample 1) that the
newest 3 samples(sample 2,3,4) will be calculated for


Digital filter [Dfilt]
Settable range
The digital filter can reduce the influence of spark
noise by magnetic of coil.
If the values of samples are over digital filter
band(fixed in firmware and about 5% of stable reading) 3
times (Digital Filter set to be 3) continuously, the meter
will admit the samples and update the new reading.
Otherwise, it will be as treat as a noise and skip the
samples.。
