6. Operation
6.5. Manual calibration
Important note:
before turning on the instrument, check that the sensor is con-
nected.
Manual readjustment of conductivity (salinity or TDS) measured at any value within
the range.
When readjusting, the instrument behaves as though it were calibrated with a
single standard solution.
6.5.1. Preparation
1. Unscrew the sensor protector.
2. Rinse the sensor with plenty of deionized water.
3. Dip the sensor into the solution in which manual calibration is to be perfor-
med.
Note: Before beginning manual calibration, you must take a measurement in the
standard to be used in the calibration.
6.5.2. Calibration
Stir gently holding the sensor by the handle.
Follow the diagram.
(1) Hold down and then press
.
Note:
if the measuring instrument is not used for 5 minutes, it shuts off automa-
tically.
If errors occur during calibration, an error message will appear on screen (see
pg. 19).
Before beginning manual calibration, you must take a measurement in the stan-
dard to be used in the calibration.
Manual calibration may be performed in conductivity, salinity or TDS. Start the
process after selecting the correct units of measurement.
Important note: To exit calibration without saving the adjustment, press .
