Connection Of Probes - Testo 252 Bedienungsanleitung

Power supply / Connection of probes
Remove batteries from the measuring
instrument and the connected option
(logger). Risk of explosion!
The measuring instrument automatically
recognises which type of probe is
connected. This does not apply to the
connection of pH electrodes without a
temperature sensor. The electrode/ probe
must be connected before the instrument
is switched on (please observe when
changing electrodes/probes).
Switch off the measuring instrument when
connecting the sensor or carrying out other
configuration modifications on the
measuring unit because the specific
parameters can only be read if the
instrument is switched on.
