To calculate and store the cell constant (K) at multiple points using different value standard
solutions:
1. From the Calibrate K menu, press the [MULTI PT] soft key.
2. Clean the container and cell (and temperature probe, if used) with deionized water.
3. Rinse the cell (and temperature probe, if used) with some of the standard solution.
4. Place the cell (and temperature probe, if used) in the solution and wait for the temperature
reading and measured K value to stabilize.
5. Using the [UP], [DOWN] and [DIGIT] soft keys, enter the value of the standard solution
at the current temperature. Temperature compensation is OFF during cell calibration.
Example: YSI 3161 Conductivity Calibrator is 1000uS at 25°C, but at 23°C you would
enter 961uS.
6. Press [ENTER] to store the current cell constant (K). Stored values are displayed at the
bottom of the screen.
7. Repeat steps 3 - 6 for the remaining solutions.
8. If you have entered less than 5 solutions, enter 0.0uS for each remaining (unused) point
and press [ENTER] to store each one.
9. When you have measured all the solutions and stored all 5 points, press [MODE] two
times to exit to the Cell menu.
10. Press the [CONFIGURE] soft key to enter the Configure menu, then press [NEXT] two
times to move the cursor to the Cell Cal field. Press the [UP] or [DOWN] soft key to
select Multi cell calibration. Press [MODE] two times to exit to Operation mode.
11. Remove the cell (and temperature probe, if used) and rinse with deionized water.

After calculating and storing multiple cell constants, the Operation screen shows the current cell
constant used during measurements. Notice that the K= changes to Km= to show that multiple
cell constants are in use.
