Two- And Three-Point Calibration - Hach sensION+ EC 5 Manual De Instrucciones

6. Operation

6.3.3. Two- and three-point calibration

Follow the diagram below.
The equipment will repeat the process described for the first stan-
dard solution with the second and third.
Dip the sensor into the tube several times to homogenize the li-
quid. Do not hold it by the tube to avoid heating of the standard
solution.
Note: if the measuring instrument is not used for 5 minutes, it shuts
off automatically.
If errors occur during calibration, an error message will appear
on screen (see pg. 19).
When you switch standards, rinse the cell with deionized water.
