Calibration Instructions for the Type
Approval Version of the SJ series
When is to Calibration Required?
Calibration may be required when the SJ series initially installed or if the scale is moved a
substantial distance.
Calibration using a Calibration Weight
1. Entering calibration mode.
Remove the calibration switch cover at the bottom of the device
and press the calibration switch while the device is in the
Weighing Mode.
Then
Cal
will be displayed.
2. Zero
calibration
Press the [RE-ZERO] key to calibrate zero.
Cal0
will be displayed.
Wait for the Stable Indicator to be displayed then press the [RE-ZERO] key.
Calf
will be displayed after a few seconds. Press the [BLIND]* key to perform only a
Zero Calibration. The scale will then automatically return to the Weighing Mode.
3. Span
calibration
When
Calf
is displayed, place the weight at the center of the platform. Wait for the
Stable Indicator to be displayed, then press the [RE-ZERO] key. The display will show
end
and the scale will automatically return to the Weighing Mode.
See “SPECIFICATIONS” about the calibration weight.
Calibration by Gravity Compensation
If the acceleration of gravity at your location is not 9.798 m/s
2
and you do not have
calibration weights, the scale can be calibrated by compensating for the acceleration of
gravity. (Refer to “The Value of Gravity at Various Locations”.)
1. Setting a new acceleration value.
When
Cal
is displayed, press the [BLIND]* key and
9.798
will be displayed. Press
the [RE-ZERO] key to increment the blinking digit and press the [BLIND]* key to move the
blinking digit.
2. Storing the value in the memory.
While pressing the [BLIND]* key, press and hold the [RE-ZERO] key and release the
[BLIND]* key. Then the display will show
end
and return to
Cal
. Turn the scale
off to finish the procedure.
Remarks*: The [BLIND] key can be activated by pressing the area between the [ON/OFF] and
[RE-ZERO] keys.
