Counter Operation - Extech Instruments SC600 User Manual

Counter Operation
For a collection of objects or pieces (each piece having the same weight as the next), the SC600
can calculate the number of these objects in a collection. A group of pieces can be used as a
sample example in groups of 10, 20, 50, or 100 pieces.
1. Prepare a group of pieces (in a group size of 10, 20, 50, or 100 pieces). This will be the
'standard' that the SC600 uses to count subsequent collections of pieces. Do not place
any pieces on the scale yet.
2. With the SC600 powered OFF, press and hold the CAL button while switching the SC600
ON
3. Hold the CAL button until one beep is heard
4. The display will count down to zero and the bottom of the display will show the COUNT
and PCS (pieces) icons
5. The display will scroll through the group sizes (10, 20, 50, and 100) one group size per
second
6. Place the group of pieces (from step 1) onto the weight platform
7. Press the CAL button when the appropriate group size (10, 20, 50, and 100) is displaying.
The display will flash twice and freeze the group size number.
8. Remove the group of pieces from the platform. The SC600 is now ready for counting.
9. Place an unknown number of pieces (of the same weight as the ones from step 1) and
the SC60 will display the number of pieces presently on the platform.
Change the Count Sample Number
1. Remove all items from the SC600 platform
2. Press the CAL button once; the display will scroll the piece group sizes (10, 20, 50, and
100) once per second
3. Place a group of pieces (10, 20, 50, or 100) onto the weight platform and when the
number on the SC600 display matches the number of pieces on the platform press the CAL
button
4. The display will flash twice and freeze the count number
5. Remove the group of pieces from the platform. The SC600 is now ready for counting.
6. Place an unknown number of pieces (of the same weight as the ones from step 3) and the
SC60 will display the number of pieces presently on the platform.
Counter Operation Considerations
The one piece weight should be larger than 0.1g otherwise errors may occur in counting. The
accuracy of the counter depends on the number of units counted. It is strongly recommended
that more samples, for example 50 units or more, be counted for the best accuracy.
