Testing The Mettler Toledo O 2 Sensor Master; Battery Check - Mettler Toledo InPro 6850i Bedienungsanleitung

InPro 6850 i / 6900 i / 6950 i O
6.1.2 Testing the METTLER TOLEDO O
We recommend to use the METTLER TOLEDO O
sensor master to check the quality of your sensor as
follows:
• Connect the sensor to the O
As soon as the sensor is connected to the
O
tomatically activated. Please note: if the sensor
was disconnected from the transmitter for longer
than 5 minutes, the sensor must be polarized
first (pola r izing time see "Section 5.1") to get
representative test results.

• Battery Check:

Push the switch to the left. If the battery is ok
and the O
green LED lights up. Otherwise, please consult
the instruction manual of the O
• Sensor Check:
For this test the O
and the membrane of the sensor must be dry
and clean.
Expose the sensor (connected to O
ter) to the air. By pushing the switch to the right
to the position "2 – Sensor check", the O
master checks wether the electrode current for air
measurement delivered by the sensor is within
the admissible range, i.e. 2500 to 6000 nA for
InPro 6950.
