Trooper Count Scale

3.3 Basic Counting

Read this procedure entirely before counting pieces. Piece sampling and counting can be further enhanced using menu
selections in the Count menu. There are several methods that are available for sampling.
• Positive Sampling - given number of pieces are placed on the scale, the weight is divided by the number of pieces
to calculate the Average Piece Weight (APW). Additional pieces are then placed on the scale and counted and dis-
played.
• Negative Sampling - calculates the APW when a given number of pieces are removed from the total quantity.
• The APW can also be entered through the numeric keypad. As parts are placed on the scale, the count is
immediately displayed.
• The Trooper Count will support positive counting or negative counting.

3.3.1 Positive Sampling

If a weighing container is to be used:
• If the tare value is known, enter a Pre-Set Tare.
• If the tare value is not known, place the container
on the pan and press the TARE button.
Press the SAMPLE Menu button.

The display indicates to place 10 samples on the scale. Place the desired number of sample pieces in the container.
If you have placed 10 pieces in the container, press the Enter button, or by pressing the numeric keys you may directly
enter an alternate sample size. Increased sample size results in better results. If you make a mistake, press the Clear
button and start again. Press the Enter button. The example indicates a sample size of 10 pieces.

3.3.2 Negative Sampling

Negative sampling permits the determination of the total quantity on the pan by removing a known number of sample
pieces. The total quantity may be placed directly on the Scale or in a container. The Trooper Count Scale automatically
calculates the remaining pieces after the sample amount is removed. When a container is used, you may enter a
preset tare weight or simply tare the empty container before starting.
