Hach 900 MAX manual Section, Calibrating the Conductivity Temperature

Section 5

Note: Conductivity temperature calibration is only necessary when logging temperature.

c.If the calibration temperature is lower than the labeled value, then subtract that value from the standard (1.0 mS) to get the actual value to be used for calibration.

1.0mS - (correction factor) 0.13002 = 0.86998 mS

d.If the calibration temperature is higher than the labeled value, then add that value to the standard (1.0 mS) to get the actual value to be used for calibration.

7.Using the value that was calculated in step 6, enter the conductivity of the solution then press ACCEPT to complete the calibration.

Calibrating the Conductivity Temperature

1.Place the probe in a liquid and wait for the temperature reading to stabilize.

2.Enter the actual temperature of the liquid (the current reading is shown for reference). Temperature calibration is complete.
