Counting by First Determining Error of Count (Two-Switch Method)
1. If a container will be used to hold the items being counted, place it on the platform.
2. Press the SAMPLE SET switch for two seconds. "AddXXX" will appear on the display
(where "XXX" is one of the pre-programmed sample sizes). Select the desired sample size by
repeatedly pressing the SAMPLE SET button or key in a new sample size.
3. Place the sample onto the platform all at one time (this should be done if the parts are
extremely small) or count them onto the platform one at a time.
4. The display will show the percent error/accuracy. Continue to count parts onto the platform,
as the sample increases the percent error will decrease and accuracy will increase. When the
percent error/accuracy is acceptable key in the quantity of parts on the platform and press
ENT.
Counting by First Determining Error of Count with Automatic Sample-To-
Bulk Feature (Two-Switch-Method)
1. Press the BASE/1 switch to select the bulk base. (BASE 2 light should be lit)
2. Press the ZERO to zero the bulk base.
3. If a container will be used to hold items on the bulk base, place the container on the platform
and press ZERO or TARE.
4. If a container will be used to hold the sample parts, place it onto the sample base at this time.
5. Press the SAMPLE SET switch for two seconds. "AddXXX" will appear on the display
(where "XXX" is one of the pre-programmed sample sizes). Select the desired sample size by
repeatedly pressing the SAMPLE SET switch or key in a new sample size.
6. Place the sample onto the platform all at once (this should be done if the parts are extremely
small) or count them onto the platform one at a time.
7. The display will show the percent error/accuracy. If the percent error/accuracy is not
acceptable, continue to count parts onto the platform, as the sample increases the percent
error will decrease and the percent accuracy will increase. When the percent error/accuracy is
acceptable, key in the quantity of parts on the platform and press ENT.
8. The scale will switch to the bulk base. Items may now be counted on the bulk base.
Negative Counting, Sample Removed (Two Switch Method)
1. With nothing on the scale platform, press the TARE to set tare to zero.
2. Place the container with contents on the platform.
3. Press the SAMPLE SET switch. “AddXXX” will appear on the display (where “XXX” is one
of the four pre-programmed sample sizes). Select the desired sample size by repeatedly
pressing the SAMPLE SET switch, or key in an alternative sample size.
4. Remove the displayed sample quantity from the container. The display will show the percent
error/accuracy (If selected in calibration). Press ENT.
5. The scale will enter the count mode and display the number of parts removed from the
container as a negative number. Removing pieces increases the negative count.
