5 Calibration
The config/cal switch must be set to the ON position in order to calibrate the indicator.
5.1 Calibration Mode
1.
Access the setup mode by pressing the
[SETUP]
key for 3 seconds.
2.
Use the
[PRINT]
key to select the CAL menu.
3.
Press the
[TARE]
key to enter the calibration mode.
3a.
After entering this mode, the number of calibrations will be shown first. This
number will be increment one digit after every calibration and calibration data
saved. This counter can't be modified or erased. It counts from 0000 to 9999,
when it reaches 9999, it starts over at 0000.
4.
After the counter number was displayed, it will show "
CAL.OFF
" or "
CAL-ON
"
which depends on whether 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.
5.
Press the
[TARE]
key to go to next step.
Zero Point
1.
When ZERO is displayed, remove all weight on the scale.
2.
Press the
[TARE]
key to select zero point calibration.
3.
The ZERO will flash while capturing the zero point. After getting reasonable
data, it automatically saves the change and exits to the weigh mode.
Linearity
The scale linearity can be calibrated with a zero reference and a full scale reference or
multiple linearity weight values. The linearity calibration is determined by the settings
in the CAL-LINE parameter.
1.
When LINE is selected, press the
[TARE]
key to enter linearity calibration.
2.
CAL.P0
will be displayed with a zero value. Remove all weight on the scale
and then press the
[TARE]
key to confirm zero point calibration. The zero
weight will flash while capturing the zero point. After getting the reasonable
zero-point data, the zero weight will become steady and then go to next step.
3.
When first default standard weight is displayed after
CAL.P1
being shown.
The default standard weight is 100%FS. Use the
[HOLD]
,
[PRINT]
,
[N/G]
,
[UNIT]
keys to input the value of the loaded weight.
4.
Put corresponding weight (more than 10%FS weight) onto scale.
NOTE: More than 10% of the full scale weight is needed for calibration.
