the container in order to induce a potential equalization between medium
and PE. If the flow rate in the container is high, a static potential may
occur locally. Place in this case the ground electrode near to the
transmitter.

1. The power supply is connected whereby the OXY 1100 sensor
points upward in the open air for two minutes. This generates a
zero point adjustment of the service life counter of the sensor. The
data of the service life counter can be read at the signal converter
(USC) or through HART

2. Place the transmitter such that the sensor OXY 1100 points
downward outside of the medium. Leave it for 1 hour in this position
so that the sensor can stabilize.
3. Calibrate the sensor in accordance with instructions
