Tampering Protection
The 620 meter is designed with tamper protection
to avoid any misuse of the meter.
The plastic register is equipped with a tamper
indicator (blue pin) whose breakage provides
obvious evidence of any tampering attempt with a
screw clamp for example. When using a metal/glass
register, a clear glass break will then occur.
The meter is always equipped as standard with
magnetic protection to protect the magnetic
transmission against magnetic fields.
Any attempt to open the meter bonnet will cause
this plastic part to break.
