Testing The Mettler Toledo O Sensor Master - Mettler Toledo InPro 6850i Bedienungsanleitung

InPro 6850i / 6900i / 6950i 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
sor master, the polarization function is automati-
cally activated. Please note: if the sensor was
disconnected from the transmitter for longer than
5 minutes, the sensor must be polarized first
(polarizing time see "Section 5.1") to get repre-
sentative 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
to the air. By pushing the switch to the right to the
position "2 – Sensor check", the O
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.
