Maintenance

A-96.250.741 / 050218

6.3.3

Replace Hydrogen Sensor

To replace the hydrogen sensor proceed as follows:

Remove the

old sensor

Switch off the AMI Inspector Hydrogen.

Close the flow regulating valve [D].

Unscrew and remove the threaded sleeve [A] from the flow cell.

Remove the hydrogen sensor [C] from the flow cell.

Unscrew and remove the sensor connector [B] from the hydro-

gen sensor.

Install the new

sensor

Screw the connector onto the hydrogen sensor and tighten it.

Put the hydrogen sensor into the flow cell.

Screw the threaded sleeve into the thread of the flow cell to fix

the hydrogen sensor.

Open the flow regulating valve and adjust the sample flow to

6–20 l/h.

Switch on the AMI Inspector Hydrogen.

Let the new sensor run in for at least 1h.
