The Zero Ready feature provides visible
indication of when the scale is not loaded,
has a valid zero calibration, and is ready to
run material. This feature is a requirement
for all NTEP scales. The indication is shown
on the display when the belt loading remains
under 0.12% of full scale belt loading for a
period of time equivalent to one belt
revolution. The indicator is the green ZERO
LED above the display. The function can be
activated only after a complete scale
calibration. A Zero Ready digital output is
also available, it is active when the green
ZERO LED is displayed.
When W&M Mode is set to NTEP, the Zero
Ready scroll defaults to “Yes”. When W&M
Mode is set to OIML or NONE, the Zero
Ready scroll defaults to “No”.
Whenever the Zero Ready scroll setting is
changed an Audit Trail event is generated.
