enable this feature, Tare is done in the terminal. If you disable this feature, Tare is
done in the IDNET base.
• When Tare is done in the terminal, the command is executed immediately.
Tare is not successful when there is motion on the scale or if there is zero
or negative weight on the scale. The DataOK bit is never turned off during
this operation.
• When Tare is done in the IDNET base, the terminal sends the Tare
command to the IDNET base. If the scale is in motion, the IDNET base
holds the tare command and suspends communications with the terminal.
If communication is suspended for more than four seconds, the terminal
turns off the DataOK bit and blanks the display. When motion stops, the
IDNET base completes the tare operation and resumes communications
with the JAGXTREME terminal. The terminal then turns on the DataOK bit.

9a. Zero Operation Sub-
block
The Zero Operation sub-block lets you set the zero reference parameters. For terminals
connected to an IDNET base, only the Auto Zero Maintenance portion of the sub-block is
accessed. For all other scale base types, you can configure any or all of these options:
Power-up Zero— automatically zeros the terminal at power-up if weight on the scale is
within a given range. If the weight on the scale is beyond the designated range, the
display will not read zero until weight falls within the range.
Pushbutton Zero— manually compensates for material build-up on the scale and
recaptures zero.
Zero Blank— determines when the display will go blank if weight falls below zero.
Auto Zero Maintenance (AZM)—automatically compensates for small changes in zero
resulting from material build-up on the scale or temperature fluctuations.
AZM w/Net Mode— automatically corrects zero close to net zero and gross zero.
Center of Zero— determines if the center-of-zero annunciator lights at gross zero only or
at gross and net zero.
Power-up zero capture and pushbutton zero ranges are based on the actual calibrated
zero. If the positive and/or negative range value for power-up zero is greater than that for
pushbutton zero, it is possible for the scale to automatically capture more weight on
power-up than can be compensated for manually.
To configure the sub-block:
1. Press ENTER at the Zero Operation prompt to open the sub-block, then press
ENTER at the Power Up Zero prompt to configure the power up zero option.
2. At the Positve Rng? prompt, enter a numeric value for the positive range of zero
capture. This value is a percent of scale capacity.
3. At the Negatve Rng? prompt, enter a numeric value for the negative range of zero
capture. This value is also a percent of scale capacity.
4. Press ENTER at the Pushbutton Zero? prompt to access these parameters.
5. At the Positve Rng? prompt, enter a numeric value for the positive capture range.
This value is a percent of scale capacity.
