5 Measurement
To make a measurement, first remove the protective cap from the electrode.
Then clean the electrode with a pHneutral liquid. Dry the electrode with adry cloth after cleaning.
Now switch on the measuring instrument with the power key (lower key). Now immerse the
electrode and the temperature probe into your test liquid. After the temperature display and the
pH display have stabilized, you can read the measured value.
When you have finished your measurement, first remove the measuring instrument from your
sample.
Now switch off the measuring instrument with the power key (lower key) and clean the electrode
before you put the protective cap back on.
6 Changing the temperature unit
To change the temperature unit, press the °C/°F key. This allows you to select the temperature
unit degrees Celsius or degrees Fahrenheit.

7 Adjustment
To make an adjustment to the meter, immerse the measuring electrode into a pH 7 solution.
Wait until the measured value has stabilized. Now set the displayed measured value to pH 7
using the calibration screw and the screwdriver supplied. The calibration screw is located below
the display. Then check the measurement against other references, for example pH 4 and pH
10. To ensure a correct measurement result, carry out an adjustment at regular intervals.
Note: Calibration and storage fluids can be purchased separately from us.
8 Inserting the batteries
To insert the batteries, first open the battery compartment on the back. Now insert the batteries.
Make sure the polarity is correct when inserting them. The markings on the batteries and in the
battery compartment may help.

They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
