Typical Uses of Y our Scale: Examples
Taring Out Box Weight Before Weighing Widgets
Suppose you wish to fill an empty box with widgets and find the weight of the widgets
in the box, not including the weight of the box. Using the tare function of your scale,
you would place the empty box on the pan, tare out the box weight, and then load the
widgets into the box. The resulting weight on the scale will be the net weight (the
weight of the widgets without the box.)
Finding the Number of Washers in a Full Box
Suppose you wish to find the number of washers in a full box, knowing the tare
weight of the box and the average weight of one of the washers. You would first place
the full box on the scale. Next, you would tare out the box by entering the weight of
the box when empty, and pressing the tare key. This would leave you with the weight
of the contents of the box. You would then enter the average weight of one of the
washers, and press the apw key. The display would show the number of washers in
the box.
Measuring the Length of Wire on a Spool
Suppose you wish to measure the length of wire coiled on a spool. Using the tare
function, you would first enter the tare weight of the empty spool. Next, using your
user-definable X units (see Appendix I), you would calculate the ratio of the weight of
one unit length of wire to a known unit; for example, pounds.
Ratio = 1 foot of wire / .1 pounds of wire = 10.
Using the conversion function, you would press the conv key until your display
weighed in pounds. Enter your ratio, and press the conv key. The display will read in
feet of wire.
Counting Resistors Placed in a Bag
Suppose you wish to count the number of resistors being placed in a bag. Using the
tare function, you would tare out the weight of the empty bag by pressing the tare key.
You would then place a known number of resistors on the pan. Using the count
function, you would enter the number of resistors on the pan, and press the count key.
The display would then read in number of resistors counted.
Kitting Microchips in Bags of 25
Suppose you wish to kit microchips in bags of 25, knowing the average weight of one
microchip. First, you would place the box full of chips on the scale. Using the zero
function, you would then zero out the weight of the full box of chips. Next you would
press the — key (indicating you are removing pieces to be kitted) and enter the
