7. Calibration
7.1 Select the load cell (1-3) for recalibration with the cell key. If the load cell has not been configured; you will
have to access the CONFIG submenu and select the load cell parameters
Access the calibration mode by pressing theSELECT key for 3 seconds or more, until you see Config
displayed.
7.2 Press theCELL key to select the Cal menu
7.3 Press the ZERO key to enter the calibration menu.
a. After entering this mode, the history of calibrations will be shown first. This number will be
increment one digit after every calibration and calibration data saved.
b. After the counter number above was displayed, it will show “CAL.OFF” or “CAL.ON” which
depends on whether the sealed calibration switch is OFF or ON. If CAL OFF is displayed, you
can still do calibration but the result will not be saved. To turn CAL ON, power down the unit and
flip the switch located on the back of the indicator under the triangle stainless steel plate, and
power back on and follow the step above.
7.4 Press the ZERO key to go to next step.
7.5 Press theCELL key to scroll to LINE
7.6 When LINE is displayed, press theZERO key to enter linearity calibration.
7.7 CAL.PO will be displayed with a zero value. Remove all weight on the scale and then press theZEROkey
to confirm zero point calibration. The zero weight will flash while capturing the zero point. After getting
the zero-point data, the zero weight will become steady and proceed to the next step.
7.8 When first default standard weight is display after CAL.P1being shown. The default standard weight is
100% of full scale. Using the SELECT, PRINT, CELL, UNIT keys to input the value of the loaded weight.
Minimum test weight value 10% of full scale.
7.9 Put corresponding weight onto the scale
7.10 Press theZERO key to confirm the calibration.
7.11 If calibration was successful, display will show END.Yand the Y is flashing. It is waiting for a command
to go onto the next calibration point or exit the calibration mode. Use the CELLorPRINTkey to select
End.y for yesor End.n for no.
a. If yes is selected, the calibration will be saved and exit to the force mode when the load is
removed.
b. If no is selected, it will go to the next step, requiring a higher calibration or linearization point.
7.12 Press the ZEROkey to confirm.
7.13 The first default standard weight is displayed after Cal.P2being shown. The default standard weight is
100 % of full scale. Use the SELECT, PRINT, CELL, UNIT keys to input the value of the loaded weight.
(More than 10% of full scale weight, and larger than the weight used on CAL.P1) onto scale.
7.14 If calibration was successful, display will show END.Yand the Y is flashing. It is waiting for a command
to go onto the next calibration point or exit the calibration mode. Use the CELLorPRINTkey to select
End.y for yes or End.n for no.
