5. SWITCHING THE METER ON AND OFF
After switching it on with the
button, the meter tests the memory and the
display on which all symbols are displayed after switching it on (Pic. 3).
Pic. 3
If the test ends successfully, after about 1.5 s the meter switches
automatically to the measuring mode, in which it was switched off. If a
sign is displayed, it means that the meter has lost the factory settings and
requires service repair. If after 1,5 s all symbols are continuously displayed, it
informs that the calibration parameters of the cell have been lost.
After pressing the button the meter adopts the K constant of the
conductivity cell K=1.000 cm
-1
and enters to the measuring mode. It will be
necessary to calibrate the conductivity cell.
The meter is switched off by pressing the
button. In case of working on
batteries, in order to save them, the meter switches automatically off after 10
minutes of non-use. This function is automatically deactivated when working
with power adapter.
