Connecting a Sensor
The HandyLab 700 provides several connections so that many types of sen-
sors can be used for measurement.
Note that only one sensor may be connected to the meter at a time.
The meter automatically recognizes a connected Memosens sensor and swit-
ches accordingly. Memosens is signaled in the display.
Caution!
Always make sure that a sensor is connected to the meter befo-
re starting measurement.
Explanation: The analog pH input of the HandyLab is an electro-
meter amplifi er with an extremely high-impedance. When the
sensor is not in contact with the medium or not connected to
the meter, electric charges on the input can generate arbitrary,
stable pH or mV values which will be shown in the display.

Memosens sensors have a cable coupling, which allows convenient replace-
ment of sensors while the cable remains connected to the meter.
The connecting cable is connected to socket a (M8, 4 pins for Memosens
sensors).
