9. Calibrationz

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.

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.
