When the [dsply]function set to be rs485, the
LED display no longer appear the input signal on
the meter then the down screen will show the data
from RS485 command. The data(number) will be
same as PV which it will compare with set-point,
analogue output and ECI functions so that is to
control analogue output, relay energized and so
on. At mean time, the energy will be accumulated
by the data in down screen.
Active power Max / Mini recording
In order to review & trace the drifting PV, the
meters will keep the values of maximum and
minimum in [ max]and [ min]of [user level]
during power on.
Active power (PV) Hold
When the [ ecI_](External Control input) set to be

■ Input Functions
500V & 50A(with YMWH-CT10A module) input
directly
●Voltage input
It can be input directly, if the measuring voltage is
under 500V. Otherwise, please connect a PT
between the measuring voltage and meter.
●Current input
The current input can be specified up to 10A or
50A. It can be input directly, if the measuring
current is under 10A. Otherwise, please connect a
CT between the measuring current and meter.
For the 50A input, we offer YMWH-CT10A
modules will compact size & high accuracy.
Input Range Function
The meters had been set the input range and
calibration as per order code (ex. 0~5A or 0~1A)
in factory. The display of active power is
calculated by the input current, voltage and the
setting of PT and CT in [input group]. Please
refer to the description as below,
●Voltage input
The voltage input is 0 ~ 500Vℓℓ max. User can
connect directly to the meter if the measured
voltage is under 500Vℓℓ. In the case of PT installed,
user just set the primary and secondary voltage of
PT. The meter will calculate and display the active
power.
►The setting for voltage
Primary Voltage unit of PT: v (V) / k v (kV)
Primary Voltage of PT: 50.0V~999.99KV
Secondary Voltage of PT: 50.0~500.0V
●Current input
The current input is 0 ~ 1/ ~ 5/ ~10/ ~ 50A. The
input range will be fixed in factory. If user specifies
the input for 50A input, please connect the meter
with the current transformer module
(YMWH-CT10A) that we offer with meter. Please
find the modules in box for 1P2W:1pc, 3P3W:2pcs
or 3P4W:3pcs.
►The setting for current
Primary Current of CT: 1~9999.9A
Secondary Current of CT:1.000~9.999A
●Frequency: 50/60 Hz±3 Hz

Digital Fine Adjustment
Settable range from 0~+99999 ;
Users can get "Fine Adjustment PV" by front key
on the meter for lower and/or higher points, and if
the user want to show the current input signals that
“Just Key-In” the value.
Especially, the [pVzro]&[pVspn]are not only in
zero & span of PV, but also any lower point for
[pVzro]& higher point for [pVspn]. The meter will
be linearization automotive for full scale.
The adjustment can be cleared in function
[ZSclr].

*Please make sure that the [pVzro]point must be
less than [pVspn]during the process of digital
fine adjustment. Generally, the internal should be
over 50% of input range. That may be made
bigger error in zero and span, if the interval is too
narrow.
■ Reading Stable Functions
Average Display update
Settable range: 1~99 times;
Jittery Display caused by the noise or unstable
signal. User can set number to average the
readings to get smoothly display.
Remark: The higher average setting will impact the
response time of Relay and Analogue
output slower.
The meter’s sampling is 15cycle/sec. If the
[ avg](Average) set to be 3 , the meter will
express the sampling 3 readings and calculating
the average then update the display once. At
meantime, the display update will be 5 times/sec.

(Sample 1 + Sample 2+ Sample3)/3
Display Update Value =

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
[mVavg](Moving Average) set to be 3 , 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
3reading, and calculating the average then update
display. At meantime, the display update will be 15
times/sec.

Digital filter
Settable range from 0(None)/1~99 times.
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.

solving the issue. It's very important idea for
electrical safety and human protection.
If the PV Higher (or lower) than set-point, the relay
will be energized and latch until manual reset by
from key in [user level]or [ eci](ECI) input.

control cabinet, it does normally can not get the
remote function. It's very easily to get the status of
switch and remote ON/OFF of the switch from CS2
series with RS485 function.
If the [ry_.md]has been set do, the relay will
be energized by RS485 command directly, and no
longer to compare with set-point.
Start delay band and Start delay time
The functions have been designed for,
1. To avoid alarm for the starting current of
inductive motor(6 times of rated current).
2. If the ry_.md relay energized mode has been set
to be lo(Lo) or lOhld(Lo & latch), the relay
will be energized, when the meter is power on
and no input due to the "0" display. User can set
a band and delay time to inhibit the energized of
relay.

Hysteresis(Fig.3-)
Settable range from 0~9999 Counts
The function is to avoid the relay on and off
frequently, when the display value is swing near by

compressor. User can set a band to prevent the
relay on and off frequently
Relay energized delay(Fig.3-)
Settable range from
0.0(second)~9(minutes)59.9(seconds);
The function is to avoid the miss action caused by
noise. Sometime, the display value will swing
caused by spark of contactor. User can set a
period to delay the relay energized.

■ 2 External Control Inputs(ECI)
The meter offers 2 point external control inputs
(ECI). They can be programmed individual with
versatile display and control functions. The front

Front Key Function
●The
Key can be set to be the same function as
the setting of [ecI1](ECI).
Ex. The [ecI1]set to be pVhld and the function
[E1=up]set to be yes in [eci group]. When
user presses
Key, the PV will hold as like as
terminals of ECI1 close.
●The
Key can be set to be the same function as
the setting of [ecI2].
Ex. The [ecI2]set to be reL.pv and the function
[E2=dn]set to be yes in [eci group]. When
user presses
Key, the PV will show relative
value as like as terminals of ECI2 close.
If the front key function has been set, the
terminal input for ECI will be disabling.

Please don't change the default setting
(500.0), if the system dosen't install PT.
Remark:
Please pay attention to the setting of unit
of volatge on last page. the meter will
combine the setting of unit(Vunit) and
value(pTpri) to caculate the display.
For example,
Once the Vunit set to be kv ,and
the pTpri set to be 45)0, It means the
setting of Pt's primary is 450.0KV。
