greater the accuracy) and press the SAMPLE soft key.

4. Select a soft key corresponding to the sample size or key in the amount of
sample pieces with the numeric keypad and press ENTER.
5. If the input is accepted the scale will revert to the Home Screen. The top half
of the screen will be updated with the necessary information.
6. Add more pieces to the scale platform to count the entire batch of items.
When the current counting session is completed simply re-sample a new batch of
items or exit the counting mode by pressing the EXIT soft key.
7.3.2 TARE - How To Tare a Container
There are two ways to Tare a Container.
1. Simple Tare (place empty container on scale)
2. Keyboard Tare (pre-tare)
To maintain the count accuracy, the following guidelines should be followed:
• All items placed on the scale must be of uniform weight.
• The more pieces sampled the greater the accuracy. For example, a sample of
50 pieces will result in a MUCH more accurate count than a sample of 10
pieces.
• Always make sure the scale weight display reads zero prior to sampling.
• The minimum sample count is 10 pieces but always try to sample more pieces
especially with light items.
• The minimum weight per piece should be 0.1 ounces or greater.
• The total weight of the items sampled must be 1 ounce or greater.
