9. Calibrating the Balance
Since electronic balances are affected by gravity gravitational acceleration, they produce different values in various
locations. Therefore, before use, balances must be calibrated at the location where they are installed. Calibration is
also required after long periods without use, or if a balance begins to produce inaccurate values.
Calibration of a balance, or “span adjustment,” is required to produce accurate measurements.
※ Span adjustment should be performed with the balance installed perfectly level and without any load on the
measurement pan.
1 Activating the span adjustment function Press and hold down the Function key.
Release the key when the display
changes from [
Func
] to [
Cal].
2 Starting the span adjustment Press the Function key while holding
down the Zero/Tare key, then release
both keys simultaneously. The display
flashes [
on 0
], indicating that
zero-point calibration is underway.
3 Zero calibration Zero-point calibration is finished when
the display changes to [
on
F.S
].
Proceed to the calibration of the capacity
point.
