The instrument automatically switches to a flammable gas setting of methane while
in use with the Enforcer. On completion it will revert to the flammable gas that the
instrument is set to measure. No intervention by the user is required.
5� Fault Finding and Procedures
There are two levels of fault within the instrument.
The first level is a warning, from which the user may be able to recover, e.g. a low
battery. The user must press the 3 button to confirm the warning has been seen.
The second level is usually non-recoverable by the user, and in some cases the
only action available is to switch the instrument off.
In both cases a warning/fault code number is given with a brief description of the
fault, and a contact name/telephone number to enable the user to further assistance
if required. Details of the warning and fault codes are given in Appendix A.
