These operating instructions are based on operator guidance by

application in accordance with DVGW Note G 465-4:

– Testing in houses/buildings (

House

application)

– Testing in enclosed spaces (

Enclosed spaces

application)

– Warning against explosive gas concentrations

(

Warning %LEL

application)

– Measurement of gas concentrations

(

Measuring VOL%

application)

Note:

The factory default operator guidance setting for the

device is

Application

. This can be changed to

Sen-

sor
