4.4 QUICK CALIBRATION OF ZERO
Useful for calibrating just the ZERO point when a permanent TARE weight is added to the scale (for example a roller
unit).
1)
Enter in the SET-UP ENVIRONMENT of the scale (upon start-up, press for an instant the TARE key while
the firmware version is displayed ).
2)
Enter the step
SEtuP >> ConFiG >> 0.CALib
and press PRINT (the display shows "CAL.0?"
.
3)
Tare Acquisition
Put the tare on the scale and press PRINT to confirm the operation.
4)
Saving the Calibration
Once the zero calibration is made, press various times the
C - ON/OFF
key until the indicator shows
"SAVE?" in the display: confirm with PRINT to store and return to weighing.
4.5 THEORETICAL CALIBRATION
Premise:
it’s possible to use this procedure if one does not have a sample weight available for carrying out a
real calibration.
1)
Follow the steps described in par.
4.1
up to point 10) (independent channels), otherwise follow the steps
described in par.
4.2
up to point 4) (dependent channels)
2)
Select the "thEo.CA" step and press
3)
Setting cell sensitivity in mV/V
Select the “CEL.SEn” step; press
, enter the cell sensitivity in mV/V (up to 99.99999 mV/V) and
confirm with
.
In case of various connected cells through the junction box, enter the average of the value; in case of
dependent channels, enter the sum of the value.
4)
Setting cell capacity
Select the “CEL.CAP” step; press
, enter the cell capacity (the unit of measure is the one
configured for the scale, up to 999999) and confirm with
PRINT.
5)
Setting pre-load weight
Select the “dEAd.Ld” step; press
, enter the weight of the structure bearing on the load cells.
The first character indicates the sign: '0' indicates a positive value, '-' indicates a negative value.
The sign is changed by positioning on the first digit and press on the up arrow / down arrow keys:
with 3 decimals: from -9.9999 to +9.9999
with 2 decimals: from -99.999 to +99.999
with 1 decimal: from -999.99 to +999.99
with 0 decimals: from -9999.9 to +9999.9
Confirm with the
key.
Note:
enter 000000 if one does not know this value.
6)
Acquisition of a known weight
Select the “Kno.WGt” step and press
; the "GET.WT?" message appears; enter the known value
(value included between 0 and the scale capacity, the unit of measure is the one set for the scale) and
press
.
Note:
by setting 0 one acquires the weight of the bearing structure on the cells.
In case of unstable weight the "ER.MOT" message will appear for a second, and one will be asked if one
wants to repeat the operation ("REPET?" message).In this case press
to repeat the operation.
Once the procedure is finished, press the
C
key to exit the calibration; one will be asked whether to apply the
new calibration (“th.CAL?”). Press
to confirm, or
C
to cancel.
Note
: once the calibration is confirmed, the indicator sets the capacity of the cells (“CEL.CAP” step) equal to the
scale capacity; consequently the values of the other steps are automatically recalculated.
If there are various scales, repeat the previous passages by selecting the desired channel (
SEtuP >> ConFiG >>
Chan
>> 1..4
).
