Reading Stable Function
Average display:
Jittery Display caused by the noise or unstable signal. User can set the
times to average the readings, and to get smoothly display.
The meter's sampling is 15cycle/sec. If the [ avg ](Average) set to be
to express the display update with 5 times/sec. The meter will
3
calculate the sampling 1-3 and update the display value. At meantime,
the sampling 4-6 will be processed to calculate.

Sample1 Sample2 Sample3 Sample4 Sample5 Sample6 ......
Display Update Value= Display Update Value=
(Sample 1+Sample 2+Sample 3)/3 (Sample 4+Sample 5+Sample 6)/3
Remark: The higher average setting will cause the
response time of Relay and Analogue output slower.
Moving average:
Jittery Display caused by the reasons as like as noise or unstable
signal. User can set the times to average the readings, and get
smoothly display.
The meter's sampling is 15cycle/sec. If the [ Mavg ](Moving
Average) set to be 3 expressed 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
the updated display value.
Moving Average set to be 3
Sample1 Sample2 Sample3 Sample4 Sample5 Sample6 ......
In first 3 samples, Display Update Value
= (Sample 1+Sample 2+Sample 3)/3
Display Update Value=
Display Update Value=
Remark: The higher moving average setting wouldn't cause the response
time of Relay and Analogue output slower after first 3 samples.
Digital Filter: The digital filter can reduce the magnetic noise in field.
The digital filter can reduce the influence of spark noise caused by
magnetic of coil.
If the values of samples are over digital filter band (fix 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.

Hi.HLd hIhld (Lo.HLd lOhld ) :
The relay energized with latched function is for electrical
safety and human protection.
For example, a current meter relay installed for the over
current alarm of motor. Generally, over current of motor
caused by over load, mechanical dead lock, aging of
insulation and so on.
Above cases will alarm in the meter, if the user doesn't figure
out the real reason and re-start the motor. It may damage
the motor. The functions of Hi.HLd & Lo.HLd are designed
must be manual reset the alarm after checking out and
solving the issue. It's very important idea for electrical safety
and human protection.
As the PV Higher (or lower) than set-point, the relay will be
energized to latch except manual reset by from key in [ user
level] or [ eci ](ECI) set to be rYrst rYrst is closed.
