TARE
A tare weight can be entered on the GuardianXL in two ways – Pushbutton Tare or
Digital Tare entry.
To use Pushbutton Tare, simply place the tare item on the scale platform and press
TARE. The scale will store this tare weight, automatically switch to Net weight mode
and display zero weight. If you switch to the Gross mode by pressing the GROSS/NET
pushbutton, the actual tare weight will be displayed. If the tare item is then removed from
the scale, the scale will display the negative tare weight in the Net mode and zero in the
Gross mode.
To enter a Digital Tare, enter the weight through the keypad. The tare must be a positive,
non-zero weight. This will place the indicator into entry mode and once the desired
weight is entered press TARE to save the tare weight. If any errors are made while
entering the tare weight, press CLEAR and reenter the weight. After the tare weight is
stored, the scale will show zero in the Net mode when the tare item is on the scale. When
the scale is empty, the scale shows the negative tare weight in the Net mode and zero in
the Gross mode.
To recall the tare weight at any time, press MENU and TARE. The main display will
indicate the tare weight in the currently selected units. The secondary display will show
“RECALL TARE”. To exit this mode press CLEAR.
To clear a tare weight press 0 on the keypad then TARE. This will remove the tare from
memory. If not cleared, the TARE weight will remain in memory, even if the indicator is
turned off.
GROSS / NET
Press the GROSS / NET pushbutton to switch the display mode from gross weight to net
weight, or from net to gross modes. The current mode is indicated on the secondary
display with the word “GROSS” or “NET”. If a tare value has been entered, then the net
value is the gross weight less the tare weight. If a tare is not currently stored, the display
remains in gross mode when the GROSS / NET pushbutton is pressed. When a tare is
entered the
GuardianXL switches to the Net mode automatically.
UNITS
The UNITS pushbutton permits the operator to select from six displayed weight units.
Simply press the UNITS pushbutton and the secondary display will indicate the correct
weight in the current weight unit “lb”, “kg”, “g”, “oz”, “lb-oz” or “user”. The UNITS
pushbutton can be configured to allow the selection of any combination of units listed
above, preventing accidental selection of undesired units.
PRINT
The PRINT pushbutton transmits print string data via an RS-232 cable or through the
Fiber Optic option. This feature is also used in conjunction with the Digital I/O to relay
control commands.
