AMI INSPECTOR Oxygen

Maintenance

6.6.1

Activate SWAN Quality assurance procedure

Enable quality assurance procedure on the process monitor(s) 

which shall be checked by selecting the quality level in menu 

5.1.2.1. The corresponding submenus are then activated.

NOTICE: 

The activation is necessary the first time only.

6.6.2

Pre-test

Reference instrument: AMI Inspector Oxygen:
– Check certificate; reference instrument certificate not older 

than one year.

– Check battery; Battery of the AMI Inspector Oxygen should 

be completely charged. Remaining operating time on 

display minimum 20 hours.

– Make sure that all instruments are set to the same 

temperature compensation.

– Sensor is in working condition

On-line instrument: Monitor AMI Oxytrace:
– Good order and condition; Flow cell free of particles, 

Sensor surface free of deposits.

– Check message list; Review the message list in menu 1.3 

and check for frequently occurring alarms (as for example 

flow alarms). If alarms occur frequently remove cause 

before starting the procedure.

6.6.3

Connect the sample lines

See corresponding chapter in the manual of the process monitor 

which shall be checked with a reference instrument.
The choice of sampling depends strongly on local conditions on 

site. Possible sampling:

via sample point,

via T-fitting or

via piggyback/downstream

NOTICE: 

•

avoid ingress of air, use screwed fitting,

•

sample as near as possible to the process monitor,

•

wait approx. 10 minutes, whilst measurement is running, 

until measurement value and temperature are stabilized.
