6.1 Important Information on Conductivity/TDS Monitor Calibration
This monitor has ±30% adjustment. Adjustable in 0.1 mS increments. Choose a
calibration standard that is close to your working solution.
Calibration should be performed regularly to ensure accuracy. Frequency of
calibration will vary and should be checked regularly until the required schedule has
been determined.
Do not reuse calibration solutions after calibration. Dispose of any used calibration
solution. Contaminants in the solution can affect the calibration, and eventually the
accuracy of the measurements.
NOTE: All new calibration data will over-ride existing calibration data. Minimum
calibration value is 2.5 mS.
Adjustments and Minimum Calibration Value are according to specific conductivity
meter model:
Models Calibration Adjustments Minimum Calibration Value
FM CON 1 0.1 mS increments 2.5 mS
FM CON 2
10 µS increments 250 µS
FM CON 3
1 µS increments 37.5 µS
