Action:
•
No current tare is set:
The weight reading must be stable within
±
1 division (Motion annuncia-
tor off) and has to be a positive reading. The entire range of the scale can
be Tared. If the motion condition is met the display temporarily reads
“TARE SET” and then converts to a “NET” display and the digits
register Ø. All subsequent readings are deviations from the set Tare value.
Final:
•
Tare is set, displaying NET weight.
To remove the Tare Value:
Push TARE. The Tare value is cleared, the scale returns to GROSS mode.
TEST SWITCH
Function:
Provides a functional system test and an on-demand display check without
disturbing the current weighment. Also provides calibration verification in the
form of a load cell calibration number.
Action:
To start the text sequence push TEST.
1) All digits (7 segment and 16 segment) count once from 0 to 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 to 100 on the digits. Also additional warnings
will be displayed should the battery be below 5%. The % battery life will
vary depending on whether the backlight is on or off. Note: The percent
of battery life is accurate with the “D” cell battery option only. It does
not apply to the standard 12V SLA battery.
3) The “CAL” number is displayed next. To ensure that the Cal number is
accurate the scale must be near zero in the same state that it was cali-
brated 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.
Final:
Either the reading returns to the last condition, or an error message is displayed.
