We recommend to use the METTLER TOLEDO O
Sensor-Master InPro 6900 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
Sensor-Master, the polarization function is auto-
matically activated. Please note: if the sensor was
disconnected from the transmitter for longer than 5
minutes, the sensor must be polarized first (pola -
rizing 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
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
Master) 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 (250 to 500 nA for InPro 6900).
If the green LED lights up the current for air
measurement is with in the admissible range.
