3.3.7.5 Calibration
Reset
This procedure adjusts the zero and gain factors of the A/D amplifier.
Normally, a Cal Reset is performed if the amplifier is locked in at an
extremely high gain factor and will not allow a new calibration to be
performed due to an over-load or under-load condition.
To access
"Cal Reset"
from the weigh mode:
1.
Access the Calibration Setup Menu Selection as described in
section 3.3.
2.
Press
[YES]
to access the calibration routines (see Figure 24).
3.
Press
[NET/GROSS]
to scroll to the
“Cal Reset”
calibration
method.
NOTE:
If an over-load or under-load condition exists at the time of calibration,
the calibration method prompts will not appear. Press
[CLR]
to proceed
directly to the Cal Reset procedure.
4.
Press
[ENTER]
to reset the A/D amplifier. The display then
shows the
"New Zero?"
prompt.
5.
Following a Cal Reset, a re-calibration should be performed
before exiting the calibration or setup modes. Press
[NET\GROSS]
to toggle to the desired calibration routine.
