6.3. Calibrating the conductivity sensor
Important note: before turning on the instrument, check that the sensor is connected.
The instrument must be calibrated before taking the first conductivity reading. The calibration can be performed with 1, 2 or 3 points.
6.3.1. Preparation
1. Fill the tubes with the standard solutions (note the fill level).
2. Unscrew the protector and rinse the sensor with plenty of deionized water.
3. Screw the sensor on to the tube containing the first standard.

6.3.2. One-point calibration
Dip the sensor into the tube several times to homogenize the liquid. Do not hold it by the tube to avoid heating of the standard solution. Follow the diagram on the next page. This form of calibration is acceptable when conductivity values around that of the standard solution used are being measured.
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).

ENGLISH
Changing backlighting time
Follow the diagram.
Notes: only the time of the manual backlighting of the display can be modified. You cannot change the automatic backlighting time (2 sec.) after completing a measurement. By increasing the display’s backlighting time, you reduce the autonomy of the instrument (battery life).
Continuous backlighting
In low-light environments, it is advisable to work with the screen lit.
Note: backlighting the display reduces the autonomy of the instrument (battery life).

ATTENTION!
Potentially dangerous to skin and eyes with chemical/biological exposure.
The tasks described in this section of the manual should only be performed by qualified personnel.
7.1. Cleaning the measuring instrument and accessories
Important note: never use cleaning products such as turpentine, acetone or similar products to clean the instrument, including the screen and accessories.
Only clean the carrying case and accessories with a soft damp cloth. A mild soap solution can also be used. Dry the clean parts carefully with a soft cotton cloth.
7.2. Storing the instrument
When preparing to store the instrument for long periods of time, remove the batteries to prevent leakage and subsequent damage to the measuring instrument.
7.3. Changing batteries
WARNING
Risk of fire or explosion. Use only AA alkaline batteries for the measuring instrument and ensure that
the batteries are correctly inserted in their compartment. Inserting batteries incorrectly can damage the measuring instrument and cause fires or explosions.
The batteries supplied have a useful life of approximately 400 hours.
