5.3.3 Factory settings (Reset)
Caution!
A reset sets the instrument back to the factory settings. This can lead to an impairment
of the measurement. Generally, you should perform a basic setup again following a
reset.
A reset is only necessary:
• if the instrument no longer functions
• if the instrument must be moved from one measuring point to another
• if the instrument is being de-installed /put into storage/installed
User input (

(0A3)):
• 333 = customer parameters
• 555 = History
333
= reset customer parameters
This reset is recommended whenever an instrument with an unknown 'history' is to be
used in an application:
• The 7500 RTG is reset to the default values.
• The customer specific tank map is not deleted.
• A linearization is switched to "
linear
" although the table values are retained. The table
can be reactivated in the "
linearization
"
(04)
function group.
List of functions that are affected by a reset:
555 = History Reset
After mounting and aligning the equipment, carry out a history reset before switching
on the function "
