1. Disconnects the controller and engages an inter-
nal reference signal to see if the problem is within
the instrument.
2. Disconnects the load sensors and engages an
internal (in the junction box) reference signal to
see if the cable between the instrument and the
Junction Box is causing the problem.
3. Reads the weight of each load sensor to see if the
load sensor might be causing the problem.
The ability to read the weight seen by each individual
load sensor allows use of this test to make cornering,
leveling and load sharing adjustments to the weighing
system.
AUTO ZERO
TRACKING Auto Zero Tracking indicates zero weight, as long as
any “live weight” on the scale is below the set Auto
Zero Tolerance, this function is turned on and the
scale is not in motion. This capability allows the mod-
ule to ignore material build-up in the weighing system
within a pre-set auto zero tolerance.
