FUNCTION DESCRIPTION

Display & Functions
Max / Mini recording: The meter will storage the maximum and minimum value in
[ user level] during power on in order to review drifting of PV.
PV / Max(Mini) Hold / RS 485 programmable in [dsply]

Present Value pv: The display will show the value that Relative to Input signal.
Maximum Hold maXhd / Minimum Hold miNhd :
The meter will keep display in maximum(minimum) value
during power on, until manual reset by front key in [User
level], rear terminal is close [External Control Input(ECI) ]
or press front down or up key to reset (according to setting,
please refer to the function of the ECI Group)
Please find the

Remote Display by RS485 command rs485 :
The meter will show the value that received from RS485
sending. In past, The meter normally receive 4~20mA or 0~10V
from AO or digital output from BCD module of PLC. We support
a new solution that PV shows the value from RS485 command
of master can so that can be save cost and wiring from PLC.
Other functions :
The meter is also support relative PV (∆PV) and PV hold
functions that set in [ eci group]. Please refer to
explain of ECI functions.
Settable range from -19999~+99999 counts.
Low cut:
The users can set the value range.
1. If set the positive value (X1) here to display "0" which it
expressed to be low-cut the PV between "+X1 (plus)" &
"-X1(minus)" /absolute value
PV< l Setting value (X1) l, the display will be shown 0
EX: Low Cut is set for 0.50. If the display is from
-0.50~+0.50, that will be 0.
Low Cut set to be +0.50

Low Cut is set for 0.50, if the PV is
from -0.50~+0.50, that display will be 0.
2. If set the negative value (X2) here to display "X2" which it
expressed to be low-cut the PV that it's under the X2 setting
value;
PV< Setting value(X2), the display will be shown X2.
EX: Low Cut is set for -0.01. If the display is < -0.01, and all
the display will be -0.01.

function
Low Cut is set for -0.10, if the PV is
under (< = -0.10), that display will be -0.10.
Settable range: -19999~+29999
Digital fine adjust:
Users can get Fine Adjustment for Zero & Span of PV by front key of the
meter, and "Just Key In" the value which user want to show in the
current input signals.
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 for full scale.

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.
