CS1 SERIES–OPERATION MANUAL(EN)-2013-01-04
Moving Average update
Settable range: 0(no function)/1~10 times;
Jittery Display caused by the reasons as like as
noise or unstable signal. User can set number to
average the readings, and get smoothly display.
Remark: The higher moving average setting wouldn’t
impact the response time of Relay and Analogue
output slower after first 3 samples.
The meter’s sampling is 15cycle/sec. If the
(Moving Average) set to be
, in the first
cycle will be same as average function. In following
cycle, the function will get a new fourth reading and
throw away first reading to be newer 3 reading, and
calculating the average then update display. At
meantime, the display update will be 15 times/sec.
Moving Average set to be 3
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
Display Update Value
= (Sample 4 + Sample 5 + Sample 6)/3
Digital filter
Settable range from 0(None)/1~99 times.
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.
Digital Filter set to be 3
The values of samples are
two times only, so that the
reading will admit the
samples.
The values of samples are
over the filter band and three
times, so that the reading will
accept the samples, and
update the reading.
●Hi alarm & latch / Lo alarm & latch (
/
)
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
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 reset by down key, if the
function in
has been set to

Start delay band
and Start delay time
The functions have Been designed for,
●To avoid starting current of inductive motor (6 times of
rated current) with alarm.
●If the
relay energized mode had been set to be
(Lo) or
(Lo & latch). As the meter is power on
and no input to display the "0" caused the relay will be
energized. User can set a band and delay time to inhibit
the energized of relay.
●Start band
(Fig.2-
):
Settable range from 0~9999 Digits
●Start delay time
(Fig.2-
):
Settable range from
0.0(second)~9(minutes)59.9(seconds);
■
CS1 series offer the 1 relay output with flexible and
versatile functions. They can be programmed in
Please refer to the description as following;
Relay energized mode Hi / Lo / Hi.HLd / Lo.HLd
●Hi(Fig.1-
) (
): Relay will be energized,
when PV > Set Point
●Lo(Fig.1-
) (
): Relay will be energized,
when PV < Set Point
