6.1 4.1.6 Unintended adjustment
It shall be possible to secure the adjustment of the measuring system against illicit
or unintended adjustment during operation.
6.2 Equipment
No additional equipment is required to test this performance criterion.
6.3 Testing
The measuring system may be operated using the display and control panel on the front side
of the instrument or from an external computer connected to the RS232 or Ethernet ports.
The instrument does not have a built-in mechanism (password protection) to protect it
against unintended or unauthorized re-adjustment. Changing parameters or adjusting sen-
sors is only possible by pushing several sequences of keys.
As the system may not be set up outside, protection against unintended or unauthorised re-
adjustment will have to be ensured by mounting the instrument at places where it is not pos-
sible to gain unauthorised access (e.g. locked measuring container / measuring cabinet).
6.4 Evaluation
Instrument parameters which affect measurement characteristics need to be typed in manu-
ally in complex key sequences (up-/down keys) and confirmed. It is not possible to make un-
intended adjustments.
In order to protect the measuring system against unauthorised adjustments it has to be
mounted in a lockable environment (container/ cabinet).
6.5 Assessment
The measuring system itself is not protected against the unintended or unauthorised adjust-
ment of instrument parameters. It has to be operated in a lockable measuring container.
Does this comply with the performance criterion? no
6.6 Detailed presentation of test results
Not required in terms of this criterion.
