CLEAR
If you want to clear the number displayed (while in the process of entering a number),
press the CLEAR key.
ZERO
Tells the scale to display zero weight. This button is used any time the scale shows a
non-zero value with no weight on the load cell. If you press ZERO with weight on the
load cell, that weight becomes the zero condition for the scale. This can be useful to
cancel the weight of any weighing fixtures, such as barrels or boxes. When this weight
is removed, a negative number is displayed until the system is re-zeroed.
The 'zero' command will be delayed any time a change in weight is detected. While the
scale is stabilizing, the display will show “ -0-
-0- -0- -0- “. If there is continuous motion for about
15 seconds, the zero command will be rejected and the scale will return to normal
weighing.
AZT (Auto Zero Tracking)
This system contains a feature called Auto Zero Tracking (AZT), which corrects
slight zero changes during normal operation. If small weights are added while
the display is at or near zero, the scale may zero them off.
NET/GROSS
Toggles the readout between net weight and gross weight. Net weight applies only
when there is a tare set. The indicator on the left side shows if the PW800 is displaying
gross or net weight.
Net = Gross – Tare
Notes: The weight will always be net when in pieces unit.
If Net/Gross key is pressed when a total is set the error message “ E-2 E-2 E-2 E-2 “ will be
displayed. You must clear the current total before toggling NET/GROSS.
TARE
Use this button to read a tare weight into memory. This tare weight will be subtracted
from the gross weight, giving you the net weight. This is useful for canceling the weight
of a container used in weighing. A segment in the lower left corner of the display shows
that the net weight is being calculated. You may press the TARE SET/DISPLAY button
to show the tare weight anytime the scale is in net mode; the tare weight will show while
you press the button. To clear the tare press the TARE and CLEAR keys
simultaneously. Tare does not function in pieces unit.
Notes: The 'tare' command will be delayed any time a change in weight is detected. If
there is continuous motion for more than 20 or 30 seconds, the tare command
will be rejected and the scale will return to normal weighing.
Tare does not function in pieces unit.
