Testing the general status

The general status test is part of the device inspection (sec-

tion 5.1.1.1

). It is based on estimations by the user. The following 

must be tested:

 

Housing

 

Signals

 

Probe

 

Filter

 

Pump

The battery charge status and the working condition of the con-

trols are automatically tested during the integrated device in-

spection.

The device inspection has been opened (section 5.1.2.1

).

1.  Select 

General status 

from the 

Device inspection

menu.

2.  Test all associated subitems as described in section 5.1.3.1
