3.2.9 Using PLUs (optional keypad only)
PLUs (Part Look Up) are use to quickly recall up to 40 items’ tare and piece weights
using a number (1-40) and the PLU key. You can also enter the part number associated
with the PLU number. It must be a 3-7 digit part number. PLUs are entered into the
ZK830 through the password protected Supervisor menu.
To recall a PLU, key in the PLU number or the 3-7 digit part number and press
PLU
.
The stored piece weight, tare weight and units are now active.
Repeat this process for other PLUs.
Updating PLU stored tare and piece weights
If enabled in the password protected Supervisor menu, you can update the stored tare
weight for a PLU or a piece weight. With an active PLU, to update a either weight press
the
PLU
key and the current PLU number is displayed, press the
PLU
key twice and
uPdAting
is briefly displayed. The new tare and/or piece weight is now stored.
If you do not place a sample on the scale within five minutes of selecting the sample
size, the display will show
tmout
(timeout) and return to the gross weight screen.
Minimum sample weight is defined as
0.01% of capacity in dribble mode or 0.02% of
capacity for bulk mode.
Press
SELECT
to see the accumulated count total. The total is erased when a new
piece weight is established, a new PLU is selected or the if the ZK830 is powered off.
CAUTION: Using a PLU assumes the individual piece weights are identical
between batches. If humidity or manufacturing tolerances can affect your parts
and you are unsure if piece weights are the same, you may get more accurate
counting if you do a new sample to get the latest piece weight.
