leveling and load sharing adjustments to the weighing
system. The Hardy Configuration Software is highly
recommended for use with this option.
Auto Zero Auto Zero Tracking will indicate zero weight, as long
as any “live weight” on the scale is below the set Auto
Zero Tolerance and the scale is not motion. This capa-
bility allows the module to ignore material build-up in
the weighing system within a pre-set auto zero toler-
ance.
Note The amount of weight zeroed off is cumulative. The
zero command will fail if the current gross weight plus
any previously zeroed amount exceeds the zero
tolerance.
Set Point TTL
Outputs The HI 1746-WS is equipped with two (2) standard
Digital TTL (Transistor - Transistor Logic) Level
Outputs which can be connected to external solid state
relays. Both outputs have individual set point, preact
and deadband parameters. Both outputs are rated at 10
milliamps per line. Each can be programmed to
respond to the standard Net, Gross, Rate of Change
(ROC), Excitation Monitor, Force On or Force Off
mode of operation.
