Calibration/Adjustment*
Always calibrate/adjust the balance/scale after setting it up in a new location.
Available Features
Calibration/adjustment can only be performed when
– there is no load on the balance/scale,
– the balance/scale is tared,
– the internal signal is stable.
If these conditions are not met, an error message is displayed.
The weight required for calibration/adjustment is displayed (see “Accessories”
for calibration weights).
On Basiclite balances, calibration/adjustment can be performed
with any of three weight units: g, kg, or lb (menu code 1. 4. x)
Factory setting: Grams (menu code 1. 4. 1)
