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
express the display update with 5 times/sec. The meter will calculate the sampling 1-3
and update the display value. At meantime, the sampling 4-6 will be processed to
calculate.
Average set to be 3
Sample 1 Sample 2 Sample 3 Sample 4 Sample 5 Sample 6
Display Update Value =
(Sample 1 + Sample 2 + Sample 3)/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
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
Sample 1 Sample 2 Sample 3 Sample 4 Sample 5 Sample 6
In first 3 samples, Display Update Value
= (Sample 1 + Sample 2 + Sample 3)/3
Display Update Value
= (Sample 2 + Sample 3 + Sample 4)/3
Display Update Value
= (Sample 3 + Sample 4 + Sample 5)/3
Remark: The higher moving average setting wouldn't cause the
response time of Relay and Analogue output slower after first 3
samples.
The digital filter can reduce the magnetic noise in field.
Digital Filter:
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.

such as compressor.......etc.,
Relay energized delay ry_.rd (Fig.3-): Settable range from 0.0(s)~9(m)59.9(s);
The function is to avoid the miss action caused by noise. Sometime, the
display value will swing caused by spark of contactor...etc.. User can set
a period to delay the relay energized.

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 is closed.

switch from CS2 series with RS485 function.
If the [ry_.md] had been set do, the relay will be
energized by RS485 command directly, but no longer to
compare with set-point.
