Measurement
Once you have completed all preparations, you can start with
the actual measurement.
1) Connect the desired sensor to the meter. Some sensors
require a special preparation. Information on this can be
found in the sensor’s user manual.
2) Switch the meter on using the
on/off
or
meas
key.
3) Depending on the measurement method and the sensor
used, immerse the sensing part of the sensor in the medi-
um to be measured.
4) Watch the display and wait for the reading to stabilize.
5) By pressing the
STO

value (see data logger, page “Data Logger” on page 26).
Measurement can also be controlled using the Paraly SW 112

display by pressing the
meas key. With a pH/ORP combo
sensor connected, the display toggles between the pH and
