Zero
- This key sets the indicator to display zero provided the following conditions are met:
1. The indicator is displaying Gross weight.
2. The displayed weight is within the zero reset range that is programmed in F4 of the Setup
(“F”) Menu.
3. The scale is not in motion.
4
. The scale is not in overload (see Appendix D for error codes).
1
. The scale is not in overload (see Appendix D for error codes).
7.3 GENERAL SCALE OPERATION
7.3.1 WEIGHING AN ITEM
1. Select the desired weighing unit by pressing the
UNIT
key until that unit is indicated on
the display.
2. If necessary, press the ZERO key to obtain a weight reading of zero.
3. Place the object to be weighed on the scale’s platter and allow the weight indication to
stabilize. If the item weight exceeds the scale’s weight capacity, it displays “
!!!!!!
”.
4. Read the weight shown on the display.
7.3.2 ZEROING THE WEIGHT OF AN ITEM
To weigh an item in a container, the weight of that container must first be subtracted from the
overall weight to obtain an accurate weight reading.
1. Select the desired weighing unit by pressing the
UNIT
key until that unit is indicated on
the display.
2. Place the empty container on the scale’s platter and allow the weight indication to stabi-
lize.
3. Press the ZERO key. The display shows zero weight.
4. Place the material to be weighed in the container and allow the weight indication to stabi-
lize.
5. Read the weight shown on the display.
7.3.3 PIECE
COUNTING
IMPORTANT NOTE:
The piece counting function cannot be used in commercial (NTEP) ap-
plications.
This mode is used to indicate the number of pieces of an item you have placed on the scale’s
platform and is accessed by pressing the UNITS key. To ensure accuracy, the parts you are
counting must be consistent in weight.
The indicator uses the sampling method to determine the average piece weight (APW) of the
items you wish to count. When sampling items, always count the parts in your hand and
place them on the platform all at once. If the APW of the items is too light or the total weight
of the sample is too light, accuracy cannot be guaranteed. You will get an error message, but
piece counting will still be allowed.
1. If the items you will be counting require a container, you must first tare the container off by pressing
the ZERO key.
