9. Calibration
The ELB-series electronic balance measures the weight using the gravity of the earth. Since the
acceleration due to gravity varies slightly from region to region, the sensitivity must be calibrated when
the balance is installed. Perform sensitivity calibration also in the following cases: (1) when there was a
large fluctuation in room temperature, (2) before conducting measurements requiring a high degree of
accuracy, (3) when moving the balance from one place to another, and (4) as periodical maintenance
once a month.

Press the [TARE] key.
The value of the weight to be used for
calibration flashes on the display.
Place the calibration weight on the pan.
(Refer to “17. Specifications” for
information on the calibration weight.)
Press the [TARE] key when the stability
mark illuminates.
Zero flashes on the display.
Remove the weight from the pan and
press the [TARE] key when the stability
mark is displayed.
“
End
” appears on the display and it reverts
to the weight display.
CAUTION!
The internal values of the balance are being revised while “End”
is displayed. Do not turn off the power while “End” is displayed.
- “
C E4
” is displayed if an improper
weight is placed on the pan, disenabling
calibration.
