7.7 P6.0 Selecting the cell constant
This program allows you to select the appropriate cell constant of K = 0.1, 1.0 or 10.0
which is suitable for measurement range being used.
Use a cell of K = 1.0 for mid-range 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.
1. From measurement mode, press SETUP key to enter into setup [SETUP] mode.
2. Use MI/▲ or MR/▼ key to scroll through the main-menu “CELL P6.0” and press
ENTER key to enter into the selection options for the cell constant.
3. Use MI/▲ or MR/▼ key to select the cell constant between K = 1.0, 0.1, or 10.
4. Press ENTER key to confirm selection and to return to the main-menu. Press
CAL/MEAS key to return to measurement [MEAS] mode.
NOTES:
When using a cell of K = 0.1, the lowest measuring range will be 0 to 2.000 µS/cm (0 to
1.000 ppm), the highest measuring range will be 0 to 20.00 mS/cm (0 to 10.00 ppt).
When using a cell of K = 10, the highest measuring range will be 0 to 2000 mS/cm (0 to
1000 ppt) and the lowest measuring range will be 0 to 200.0 µS/cm (0 to 100.0 ppm).
