User manual - WEIGHT METER SWI-94
changes of input signal (weight) high value of „
FiLtEr
” can cause degradation of
measurement precision.
”S tESt”
- this function allows to view transducer signal value expressed in mV/V.
Procedure of theoretical calibration
1.
Set parameter „
C
tYPE
” = „
dAtA
”.
2.
Set required measurement displaying resolution (
rESOL
” parameter).
3.
Set proper working range of measurement input („
rAnGE
” parameter).
4.
Set required values of parameters „
r LoAd
” and „
r out
”.
5.
Unload scale (get weight off from a scale if it was loaded).
6.
Make zeroing using „
S Zero
” function.
After this procedure device is ready to work.
If it is impossible to get weight off from a scale if it was loaded then points 5 and 6
can be skipped. Instead it is required to enter known value of the empty scale as
an „
Z oFFS
” parameter.
Procedure of dead weight calibration:
1.
Set parameter „
C
tYPE
” =„
rEAL
”.
2.
Set required measurement displaying resolution („
rESOL
” parameter).
3.
Set proper working range of measurement input („
rAnGE
” parameter).
4.
Unload scale (get weight off from a scale if it was loaded).
5.
Make zeroing using „
S Zero
” function.
6.
Load scale with known weight.
7.
Enter the value of known (calibration) weight using „
LoAd
” function.
After this procedure device is ready to work.

”OutPUt” menu
This menu contains parameters of analogue output control.
Analogue output can be controlled depend on both present measured value and
peak value (if peak detection is enabled).
“OUtmod”
- analogue output mode. Depending on version of the device there are following
options:
For active current output:
”
oFF
”
- current output disabled
,
”
0-20
”
- current output enabled with 0 ÷ 20 mA mode
,
“
4-20
”
- current output enabled with 4 ÷ 20 mA mode,
”
modb
”
- current output controlled via RS-485 interface.
For passive current output:
”
oFF
”
- current output disabled
,
“
4-20
”
- current output enabled with 4 ÷ 20 mA mode,
”
modb
”
- current output controlled via RS-485 interface.
