1. All digits (7 segment and 16 segment) count once from 0–9. All annunciators are tested. 16 segment displays also go
through “*”.
2. Battery condition is displayed next in the form: “%” (percent) of battery life with a figure from 1–100 on the digits.
Additional warnings display if the battery is below 5%. The % battery life varies depending on whether the backlight is
on or off.
3. The Cal number is displayed next. To ensure the Cal number is accurate the scale must be near zero in the same state
it was calibrated in. The original Cal number is printed on the right battery tube calibration label. Cal number shifts of
up to 10 counts are insignificant.
4. Internal tests are performed to further ensure scale integrity.
5. The reading returns to the last condition or an error message is displayed.
