5.10. Anti-tamper Features
5.10.1. General
The Sabre meter is mechanically sealed against tampering through the use of a
factory-sealed screw plugs on the rear panels and a utility-sealed wire seal on the front
of the meter.
The use of these mechanical seals ensures that there are visible signs of tampering if
unauthorised entry to the system is attempted.
Figure 7: Factory sealed screw plugs
In addition to the factory-sealed screw plugs on the rear panels, there is a facility for two
utility wire seals on the front of the meter. The use of these utility seals also ensures that
there are visible signs of tampering.
Once the meter has been securely fitted to the common base and secured with the
screws supplied, the anti-tamper seals are clipped in place and utility seals are fitted into
the holes as shown below.
