BATTERY REPLACEMENT
If batteries become weak, the display will flash the bat-
tery symbol to advise the user that approximately 25 hours
of working time are left. It is recommended to replace
the batteries soon.
Moreover, when the battery level is too low to ensure
reliable readings, the meter automatically turns off. At
start-up the display will show “0 bAtt” for a few sec-
onds and then the meter turns off.
pH MEASUREMENTS
Remove the electrode tip protection
bottle. Submerge the pH electrode tip
(4 cm) and the temperature probe into
the sample to be tested.
If necessary, press the RANGE key
until the display changes to the pH
mode.
Allow for the electrode to adjust and reading to stabilize
(hourglass symbol turns off).
The LCD will show the pH measurement together with
the temperature of the sample.
In order to take more accurate pH measurements, make
sure that the instrument is calibrated (see “pH Calibra-
tion” section for details).
