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.
1.0 mS - (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
Note: Conductivity temperature
calibration is only necessary when
logging 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.
