3.
Check that the salt solution container contains simultaneously:
•
Salt in solid state
•
Liquid solution and wet salt.
4.
The probe and the saturated solution for this operation should have the
same temperature , and therefore should be located
in a room with a stable temperature for the entire
calibration period.
5.
Unscrew the probe protection; screw the M12×1
threaded ring.
6.
Should there be any liquid inside the measuring
chamber, dry it with some blotting paper. The
formation of liquids inside the measuring
chamber, does not impair the measurement
uncertainty of the solution or measurement.
7.
Screw the ring to the container with the saturated
solution. Avoid any contact of the sensitive element
with your hands or another object or liquid.
8.
Once the sensor has been inserted, wait at least 30
minutes, if the probe and salts have the same
temperature. Otherwise, you should wait the time
necessary to reach a balance.
9.
After 30 minutes, press ENTER. The new calibration
value has been captured by the probe connected to
the instrument.
