Introducing the Multipoint 
Power Recorder 

The Multipoint Power Recorder is designed for permanent or semi-

permanent installation of a Power Recorder in a non-hostile 

environment. The Multipoint provides the same quality and features of 

other Reliable Power Meters power recorders at a lower cost. 

 

 

Lethal voltages are present. In order to ensure 

safety the Multipoint Power Recorder must be 

installed in a protective enclosure that limits access 

to the electrical connections of the device and 

requires a tool or key for such access. Multipoint 

Power Recorders are not weatherproof. If you need 

a weatherproof unit, contact Reliable Power Meters 

about obtaining a Power Recorder with a Hostile 

Environment Enclosure.

 

 

The Multipoint Power Recorder actually contains two units—a Base 

Unit, and an Acquisition Unit, as shown on page 2. The base unit can be 

installed permanently—bolted to a wall, shelf, or panel—while the 

Acquisition Unit is removable to allow for repair or calibration, if 

necessary, without having to unwire anything or even turn the power off.  
Several different models of base and acquisition units are available.
