User manual - WEIGHT METER SWI-94
”C tYPE” - calibration type. Possible values:
“dAtA”
- theoretical calibration („Data Sheet” type calibration) according to data sheet
of load cell transducers (strain bridges),
“rEAL” - dead weight calibration (entry of values for certain known loads).
„
CALibr
” menu shows option related to selected calibration method only. When
dead weight calibration is selected then „LoAd” parameter is visible . When
theoretical calibration is selected then parameters „ r LoAd ” and „ r out ” are visible
in place of „ LoAd ”.
”r LoAd” - Rated Load calibration parameter. This parameter is expressed in kg and can be
changed in range from 000000 to 999999, making allowance for „
rESOL
”
parameter.
In case of connection of two, three or four transducers parameter „ r LoAd ” should
be set to arithmetic sum of nominal weights of all the sensors.
”r out” - Rated Output calibration parameter (output value of load cell transducer at
nominal load). This parameter is expressed in mV/V and can be set in range from
0.0000 to 1.9999 (when
„rAnGE”
= 2mV/V) or from 0.0000 to 3.9999 (when
„rAnGE” = 4mV/V).
In case of connection of two, three or four transducers parameter „ r out ” should be
set as arithmetic mean of all sensors signals.
”LoAd ” - function allowing dead weight calibration. After selection of this function it is
necessary to enter some value (expressed in
kg
) and confirm entered value by
pressing [
ENTER
] or press [
ESC
] when value needn't to be changed. To cancel
calibration press [ ESC ] after questions „ rEADY? ” appear. Pressing [ ENTER ] after
„ rEADY? ” appear causes storing current value of input signal. If input signal value
exceeds permissible range then calibration fails and message „ Err ” is displayed.
Weight is expressed in
kg
, and can be changed in range from 000000 to 999999
making allowance for „
rESOL
” parameter.
Due to measurement precision it is recommended to use weight not less than 2/3
of full scale weight while dead weight calibration. Best results can be obtained after
calibration with dead weight equal to maximum expected weight put of the scale.
”S ZEro” - this function allows to storing momentary value as “zero” of recalculation
characteristic. Storing is done directly after pressing of [
ENTER ] button.
”Z oFFS”
- Zero Offset calibration parameter. This parameter is expressed in
kg
and can be
changed in range from 000000 to 999999, making allowance for „
rESOL
”
parameter.
”FiLtEr” - this parameter defines input signal filtration rate. It can be changed in range from
0 (lowest filtration) to 5 (highest filtration) which corresponds to 26Hz , 17Hz , 8Hz ,
4Hz
,
1Hz
,
0,5Hz
. Bigger filtration level causes slower changes of measurement
results because measurements are realised with longer time interval. While fast
