Counting Scale by either the push button tare method or the keyboard tare method. A tare
weight may be entered up to and including the scale’s full capacity, however the maximum
negative weight that the scale can show is –9.9999 lbs. It is recommended that the push
button tare method be used.
3.4.1 To use the push button tare method (Recommended for better accuracy):
1. Place the empty container on the platform.
2. Press the TARE key. The TARE indicator comes on and the WEIGHT display window
shows zero.
3.4.2 To use the keyboard method:
1. Enter the known tare weight in pounds into the scale using the numeric and decimal
point keys. NOTE: You must enter all three decimal places if the tare weight is not in
whole pounds, i.e. enter 1.2 lbs. as 1.2000 lbs. This value will be blinking in the UNIT
WEIGHT display window.
2. Press the TARE key. The TARE indicator comes on and the WEIGHT display window
shows the keyed-in weight as a negative value
3.4.3 To clear the tare weight from the scale:
Remove all weight from the platform and press the TARE key. The TARE indicator goes
off and the WEIGHT display window again shows zero.
3.4.4 Possible Tare Operation Errors:
You cannot enter a tare weight that is greater than the scale’s full capacity. For example,
for the 12 lbs., you cannot enter, say, 13.000 lbs. Also, you cannot key in a decimal point
value higher than the resolution if the scale. For example, for the 12 lbs., you cannot
enter 0.001 lbs., since the resolution is 0.002 lbs. In both cases, the scale will
automatically reset itself after three seconds, or you can press the CE key to key in a
new value.
3.5 Piece Counting Operation
There are two ways to use the piece counting operation. A unit weight value can be
keyed into the Counting Scale by using the keyboard entry method. Alternatively, the
sampling method may be used. For greater accuracy, the sampling method should be
used. The accuracy of the operation depends upon part consistency and sample weight.
When using the sampling method, always count the parts in your hand and place them on
the platform all at once. Both the sample weight and the unit weigh have limits to assure
accuracy. The limits for these are found at the bottom of the page.
3.5.1 To use the sampling method:
1. Place a pre-determined number of pieces on the platform. The WEIGHT display window
shows the total weight.
2. Key in the number of pieces you have placed on the platform. This value will be blinking
