Preparation
a. Insert the 9V battery (supplied) and press the ON/OFF button to turn
on the instrument.
1 Point manual calibration
b. Remove the protective cap and pull out the electrode; if necessary
adjust the electrode's length (max. 8 cm).
c. Rinse the electrode with clean water and dry it. Dip the electrode in
the test solution (supplied), which has a known pH of 7 (25°C). Gently
stir the solution for a few seconds until the value on the display
stabilizes.
d. Set the pH to 7.0 (25°C) by using the screwdriver (supplied) to turn
the trimmer, located on the right-hand side of the instrument and
indicated by CAL► on the front.
e. After calibrating the instrument, wash the electrode in clean water and dry it.
Operation
Note: The instrument does not need to be calibrated before every use. Calibrate the instrument the first time you
use it and then recalibrate it every two weeks or after every 10 measurements.
f. Dip the electrode in the solution to be measured. Stir the solution and wait a few seconds for the value on the
display to stabilize.
g. Wash the electrode after every use and put on the protective cap. The sponge material inside the protective
cap must be kept moist at all times; add some clean water if necessary.
Changing the battery
If the instrument does not turn on or the display shows the values incorrectly, the battery needs to be changed.
- Remove the cover of the battery compartment on the back of the instrument.
- Replace the 9VDC battery with a new battery.
- Put back the cover.
