FUNCTIONS
■DISPLAY FUNCTIONS
EX：Low Cut is set for -0.01, if the display is ≤ -0.01,
and all the display will be 0.
Digital filter: seting range from 0(None)/1~99 times.
The digital filter can reduce the magnetic noise in field.
Digital Fine Adjustment: seting range from
-19999~+29999 ;Users can get Fine Adjustment by
front key of the converter, and “Just Key In” the value
which user want to show in the current input signals.
Maximum Hold or Minimum Hold:
The converter will keep display in maximum value
during power on until manual reset by front key in
【User Level】
Write to display by RS485 command
The display can be written by RS485 command. In
past, The converter nomorlly receive 4~20mA or
0~10V from AO card or BCD card of PLC. We support
a new solution by RS485 writing in so that can be
save cost and wiring into PLC.
Low Cut / Digital Filter / Digital Fine Adjustment
Low Cut: seting range from -5000~+5000 counts.
If the setting value is positive, it means the range of
absolute value will be 0; PV≤ Setting value, the
display will be 0;
EX：Low Cut is set for 0.10, if the display is from
-0.10~+0.10, that will be 0.
If the setting value is negative, it means the range of
under setting value will be 0; PV≤ -Setting value, the
display will be 0;
■RELAY FUNCTIONS
Start Delay
Hysteresis: Settable range from 0~9999 Counts
Relay energized delay: Settable range from
0.1(second)~9(minutes)59.9(seconds);
Relay de-energized delay: Settable range from
0.1(second)~9(minutes)59.9(seconds)
Relay energized mode Hi / Lo / Hi.HLd / Lo.HLd / DO
Hi:Relay will energize when PV > Set-Point
Lo:Relay will energize when PV < Set-Point
Hi.HLd (Lo.HLd): When the PV Higher (or lower) than
set-point, the relay will be energized and hold until
manual reset by from key in【User Level】.

2 / 12 ST-VA/PR/SG/PM/RS/T MANUAL -2015-09-08
DO:Relay is energized by RS485 command directly,
and no longer to compare with set-point of relay

FIELD CALIBRATION(This function is for ST-SG, ST-PM & ST-RS)
In pass time, engineers have take a lot of time to adjust meters or converter to meet the structure of machinery zero
and span for the Load Cell and Potentiometer measuring. Now, our ST-LC support easlier process to do it called
“Field Calibration”.
Field calibration can be done individual in input 1 and input 2.
Adjust the structure of machinery to be “zero status”.
Enter the right pass code of the meter to get into the Field Calibration Level.
Move page to the CAL1.L , and press
ENT
Key to stand by. Press
ENT
Key again to read the signal low of sensing
device. After it done, the page will change to CAL1.H automatically. The low point will be the new zero.
Adjust the structure of machinery to be “span status”.
In CAL1.H page, press
ENT
Key to stand by. Press
ENT
Key again to read the signal high of sensing device. After it
done, the page will change to C.SEL1 automatically. The high point will be the new span.
Reading the signal will take few seconds.
Please check the setting of high scale Hi.SC and low scale Lo.SC again, after the “Field Calibration” has done.
C.SEL1(Calibration parameter selection): Field calibration don’t change the default calibration. So, after you do field
calibration, you can select default calibration if you want.

The high calibration is not need the

Csel(C.SEL): Calibration parameter
selection;
As the user finished the procedures of
field calibration, the field calibration datum
has been saved in EEProm and it can't
change the default(factory) calibration
datum . Even the field calibration has been
done, the user can still select either default
calibration or field calibration.

◘If the user select field
calibration of the [lOsc](step
A-4) and [hIsc](A-5) will be
replaced by the [caLls] and
[caLhs]which it can not to be
change by anyone. If user has to
change the scaling, it's the only
way to access field calibration
level to set in [caLls](step F-2)
and [caLhs](step F-4).
◘Please double check the
[lOsc](step A-4) and [hIsc](A-5)
whether are correct after
selection the deflt or field.
