Six Counting Unit Tally Counter
EMS #70310-06
Before Operating
Be sure that all counter units are set at "000" prior to operation. To set at "000":
- Rotate the end knobs one full turn toward the operator.
- Mark the cell types to be counted on the removable tabs or trips provided.
Instructions
- Press down only 1 key at a time to make your count.
- Press each key all the way down and release the key completely ("deep-stroke-and-release" action) is critical in that single key stroke records your count on an individual counter as well as on the totalizer, simultaneously.
Note: The totalizer is the last counter, located on the right with no key beneath the window. The totalizer accumulates a grand total of all cells counted on individual counter keys.
- At a total of 100, the number shown on each individual counter directly represents the percentage of that cell type counted in the blood specimen.
Note: For more precise cell counts, continue this process until the totalizer reaches a total of 200 strokes. To determine the percentage of each cell counted:
- Divide the total shown on each individual cell counter by 2. Counts can be continued to a total of 300 (divide individual counter totals by 3) or to a total of 400 (dividing individual counter totals by 4).
- To count the number of cells in each square of a chamber:
- Use a separate key for each square. The totalizer will show the total number of cells counted in all squares.
- Divide the totalizer count by the number of squares counted to achieve the average count per square.
Counter Maintenance
