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 (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 the
sign is displayed, it means that the meter has lost the factory settings
and requires service. If after 1,5 s all symbols are continuously displayed, it
informs that the calibration parameters of the electrode have been lost.
After pressing the button the meter adopts standard parameters:
- drift = 0 pH, slope = 100%
and enters the measuring mode. It will be necessary to calibrate the pH
electrode.
The meter is switched off by pressing the
button.
