12. Calibration
Note:
(1) Before calibrate the scale, you should prepare a standard weight (more than 10% of FS weight) for
calibration.
(2) In following steps, to press
ON/OFF
will show “
EXIT?
”, and press
ON/OFF
again or press
TARE
will
exit calibration
12.1 Go to setup mode, select “CAL”, then press
TARE
to confirm to enter calibration mode.
12.2 After entering this mode, the number of this indicator has been calibrated will be shown first, this number
will be increased one after every calibration and calibration data saved, and this counter can’t be modified
or erased by any other ways, it counts from 0000 to 9999, when it reaches 9999, it starts over at 0000.
After the counter number being displayed, it will show “
CAL.OFF
” or “
CAL-ON
” according to the status of
the sealed calibration switch is OFF or ON. If the switch is OFF, the following steps can be done, but the
result will not be saved. Press
TARE
key to go to next step.
12.3 When “
ZERO
” is shown, use
or
ACC
key to select do zero point calibration (refer step12.4), do
linearity calibration (refer step12.5), do Geographical calibration (refer step 12.6) or Input/view calibration
parameters value (refer step 12.7).
12.4 When
ZERO
is selected, remove all weight on scale and then press
TARE
key to confirm, the
ZERO
will
flash when in catching zero point state. After getting reasonable data, it automatically goes to step12.8
12.5 When
LINE
is selected, press
TARE
key to confirm to enter linearity calibration.
12.5.1 0% weight will be displayed after
CAL.P0
being shown, remove all weight on scale and then press
TARE
to confirm to calibrate the zero point; the zero weight will flash in catching zero point state. After
getting the reasonable zero-point data, the zero weight will become steady and then go to next step.
12.5.2 When first default standard weight is displayed after
CAL.P1
being shown. It will be calibrated on
standard weight for first point. Put corresponding weight (more than 10%FS weight) onto scale. The
default standard weight is 100%FS.
Use
PRINT, ACC, UNIT
keys to input the value of the loaded weight. Before input this value, you
can long press DATA key to change weight’s unit to kg or lb. Press
TARE
key to confirm, then, the
indicator will flash the input standard weight.
When this weight number becomes steady, it means the stable and reasonable data
corresponding to the standard weight has been gotten.
After this, the indicator will automatically go to next step. If this point can’t be calibrated correctly
(maybe the weight load onto scale is too small, maybe the input data is incorrect…), it will display
“
CAL.Er
” and return back to step12.5.1 for re-calibration.
12.5.3 When
End.y
is shown and
y
is flashing, it’s waiting command to exit calibration or go on next
calibration. Use
or
ACC
key to select
yes
or
no
, use
TARE
to confirm
.
If
yes
is selected, it will
go to step12.8 to end calibration; if
no
is selected, it will go to next step.
12.5.4 When 100%FS weight is displayed after
CAL.P2
being shown. It will be calibrated on standard weight
for second point. Put corresponding weight (more than 10%FS weight, and larger than the weight
used on
CAL.P1
) onto scale. Next operation is same as what in step12.5.2
12.5.5 When
End.y
is shown and
y
is flashing, Use
or
ACC
key to select
yes
or
no
, use
TARE
to
confirm
.
Similar with doing in step12.5.3
12.5.6 When third standard weight displayed after
CAL.P3
being shown. It will be calibrated on standard
