2.10 Anti-tampering features
The following anti-tampering features are available for ZMD400xT meters:
DC magnet detection for the detection of strong magnetic fields close to
the meter. This feature is installed during the manufacturing process.
Terminal cover detection for the detection of situations when the
terminal cover has been opened. This feature can be integrated into the
meter, and is available if the DC magnet detection option is selected
and must be integrated during manufacturing process.
2.10.1 DC magnet detection
ZxD410xT, ZxD405xT and ZxD402CT meters can be ordered with a feature
which detects strong DC magnetic fields. When a magnetic field is present,
event 134 is set; when the magnetic field disappears, event 188 is set.
These events can e.g. be entered into the event log with date and time. The
meter’s type designation informs you whether this feature has been
implemented (see 2.4
With DC magnet detection, it is possible to order the integrated terminal
cover detection option.
