WEIGHING A SAMPLE
To determine the weight of a sample first tare an empty container if used, then place
the sample in the container. The display will show the weight and the units of weight
currently in use.
PERCENT WEIGHING
The scale will allow a sample weight to be shown as 100%. Then any other weight
placed on the scale will be displayed as a percentage of the original sample. For
example is 350g is placed on the scale and the % key is pressed the display will show
100.00%.
Removing the 350g weight and putting a 300g weight on the scale the display will show
85.71% as 300g is 85.71% of 350g.
Note: the scale may jump by large numbers unexpectedly if small weights are used to
set the 100% level. For example if only 23.5g is on a scale with 0.5g increments and
the scale is set to 100%, the display will show 100.00%, however a small change of
weight will cause the display to jump to 102.13% as one scale division (0.5g) increase
to 24.0g will be equivalent to a 2.13% increase.
Pressing the FUNC key will return the scale to weighing.
PARTS COUNTING
Before beginning, tare the weight of any container that will be used, leaving the empty
container on the scale.
When the scale is showing weight, pressing the FUNC key will start the parts counting
function.
Place the number of samples on the scale. The number should match the options for
parts counting, 10, 20, 50, 100 or 200 pieces.
Press the FUNC key to begin. The scale will show "SP 10" asking for a sample size of
10 parts. Change the sample size by pressing the TARE/ key. The display will cycle
through the options: 10, 20, 50, 100, 200 and back to 10.
Press the ZERO/ENTER key when the number matches the number of parts used for
the sample. As more weight is added the display will show the number of parts (pcs).
Press the % key to display unit weight (g/pcs or Lb/pcs), Total weight (kg or Lb) or the
count (pcs). Press the FUNC key to return to normal weighing. The pounds will be
shown on the TCWa scales when the weighing unit is set to pounds.
