Operations

ON/OFF
Press and hold this button 1 second to turn the scale on and off. The scale tests itself;
when this test is completed successfully the system begins weighing. The product I.D.
and software version number are display for a couple seconds upon power up. The
number on the left is the product ID and the number on the right is the software version
number.
NUMERIC KEYPAD
Many operations require the operator to enter a number. The 10-key numeric keypad is
used to enter numbers. These keys also have specific functions (as labeled) when the
scale is in normal weighing mode.
ENTER
Press the ENTER key after entering a number

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-
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.
-0- “. If there is continuous motion for about
-0- -0-
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
displayed. You must clear the current total before toggling NET/GROSS.
E-2 “ will be
E-2E-2
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.

PRESET TARE
Pressing the PRESET TARE key will bring up a screen that allows the user to enter a
tare value. Enter the tare value using the numeric keypad and then press ENTER. To
clear the tare press the TARE and CLEAR keys simultaneously.
Notes: Tare does not function in pieces unit.
UNITS/PIECES
Toggles the weighing system between pound (English), and kilogram (SI metric), and
‘pieces’ (quantity of items) units of measure. When you press this switch, the system
switches to the nearest comparable value in the selected system. The current unit of
measure is shown by indicator segments on the left side of the main display.
Note: An error message “ E-2
when there is a total saved. You must clear the current total before toggling
NET/GROSS.
E-2 “ will be displayed if the UNIT/PIECES key is pressed
E-2E-2
SAMPLE
Sample is used to so you can view the weight in pieces. Place a number of items on the
scale. A good rule of thumb is to place 3%-5% of the total number of pieces you intend
to weigh. With a known quantity of items on the scale press the SAMPLE key. Enter
the number of items on the scale. The sample measurement is saved in the scale’s
memory. The scale will switch to the unit ‘pieces’ and display the number of pieces on
the scale. To clear the sample measurement saved in memory, press the SAMPLE and
CLEAR keys simultaneously.
APW
APW is the abbreviation of Average Piece Weight. Press the APW key. Enter the
average weight of one piece. The scale switches to ‘pieces’ unit and displays the
number of pieces on the scale. To clear the APW press the APW and CLEAR keys
simultaneously.
If you need to enter piece weights less than 1 lb or 1 kg, see the APW decimal position
section in ‘Calibration’. This can setup your PW800 to record APW’s by tenths (1
decimal place) or by hundredths (2 decimal places).
