CONDUCTIVITY
CALIBRATION — AC-PHM7
STEP 7
If your estimated sample conductivity level is
greater than 2 mS or 2000 µS, you may optionally
repeat steps 2-5 to calibrate the 2
nd
point using the
12.88 mS conductivity solution instead.
"H" will appear next to "M," indicating a successful
2
nd
point calibration (low and middle points).
CONDUCTIVITY CALIBRATION NOTES
This pH meter can calibrate with 84 µS, 1413 µS, and 12.88 mS conductivity calibration
solutions. You may select the following calibration points:
We recommend replacing the solutions after their designated uses to help keep your
conductivity measurements reliable. DO NOT pour the used calibration solutions back into the
solution bottles to prevent contamination.
