P6.0 Selecting the cell constant
Your meter lets you select a cell constant of K = 1.0, 10, or 0.1.
Use a cell of K = 1.0 for midrange measurements
Use a cell of K = 10 for high range measurements (above 20 mS or 10 ppt).
Use a cell of K = 0.1 for low range measurements (below 20
µS or 10 ppm).
The cell included with your meter has a cell constant of K = 1.0.
From measurement mode

key to return to measurement mode.
NOTES
When using a cell of K = 0.1, the lowest measuring range
will be: 0 to 1.999
µS (0 to 0.999 ppm). The 0 to 199.9 ms
(10 to 200 ppt) range will not be accessible.
When using a cell of K = 10, the highest measuring range
will be: 0 to 1999 mS (100 to 2000 ppt). The 0 to 19.99
µS
(0.00 to 9.99 ppm) range will not be accessible.
