functions.
Table 1-3. Front Panel Keys
ZERO key
The ZERO key sets the current Gross weight to Zero, provided the
amount of weight to be removed or added is within the specified Zero
Range and scale is not in motion. The Zero Band can be either 100% or
2% of full scale capacity. This key has secondary functions when using
ID storage and when setting TARE/OVER/UNDER values.
UNITS key
The UNITS key switches the weight display to an alternate unit. The
alternate unit is defined in the Setup menu, and could be kg, g, lb, oz, or
lb and oz. Conversions of the weight reading, the Tare value, the Over
value and the Under value occur when the unit of measure is changed
with the UNITS key. This key has secondary functions when using ID
storage and when setting TARE/OVER/UNDER values.
PRINT key
When enabled, the PRINT key sends “on-demand” serial information
out the serial port provided the conditions for standstill are met. The
Print Out parameter defines the format for printed information. This key
has secondary functions when using ID storage and when setting TARE/
OVER/UNDER values.
TARE key
The TARE key performs one of several predetermined Tare functions
dependent on the mode of operation selected. Setup options include the
following list below. (See TARE description in section 3 for more
information). This key has secondary functions when using ID storage
and when setting TARE/OVER/UNDER values.
In SET Mode
Allows direct tare value entry via front keypad, incrementing or
decrementing as directed until the desired Tare value is displayed. The
last Tare value displayed is stored after 3 seconds of inactivity.
In PTT (push to tare) Mode
Acquires Tare value by pressing TARE key. Positive gross weight on
platter at the time TARE key is pressed is acquired. The display shifts to
the Net mode, NET LED is illuminated, and a NET weight of 0 in the
current unit of measure is displayed. Pressing the TARE key at Gross
Zero removes the tare from the system in this mode.
DIS (disabled)
Disables the Tare function. The NET weight display mode is disabled.
Entry of Tare values is not permitted. Weighing is by gross weight only.
