Connecting a Sensor
The Portavo 904X MULTI provides several connections so that many types of sensors
can be used for measurement (see illustration below). Note that only
one
sensor
may be connected to the meter at a time. The meter recognizes the connected Mem-
osens sensor and displays the Memosens logo.
Separate Temperature Probe
Note:
Temperature measurement using a separate temperature probe is only possi-
ble when no Memosens sensor is connected.
After power-on, a separate temperature probe is automatically recognized. If you
want to replace the temperature probe, you must switch off the meter and then
switch it on again.
Commissioning
Memosens sensors have a cable coupling, which allows convenient replacement of
sensors while the cable remains connected to the meter. Depending on the version,
the Memosens cables are connected to socket
b
(M8, 4 pins) or
e
(M12, 8 pins).

WARNING! Impairment of explosion protection.
Never use digital Memosens sensors or Memosens cables without Ex approval in a
hazardous location. For these applications, you must use Memosens sensors with Ex
approval. These sensors and the Memosens Ex cable are marked by an orange-red
