Safety Information
Classification
The RM3 Series Backreflection Meter consists of an exposed metal chassis that is connected
directly to earth via a power cord and, therefore, is classified as a Class 1 instrument.
Disconnecting from Line Power
Some of the circuits are powered whenever the unit is connected to the AC power source (line
power). To ensure that the unit is not connected to the line power, disconnect the power cord
from either the power inlet on the unit’s rear panel or from the AC line-power source
(receptacle). The power cord must always be accessible from one of these points. If the unit is
installed in a cabinet, the operator must be able to disconnect the unit from the line power by
the system’s line-power switch.
Line Power Requirements
The Backreflection Meter operates from any single-phase AC power source that supplies
between 100 and 240 V at a frequency range of 50 to 60 Hz. The maximum power consumption
of the Backreflection Meter is 30 VA. The unit can also be operated using its internal 6V DC
rechargeable battery.
Fuse Type
The fuse type used by the unit is (5 x 20) mm, F1A/250 V.
