Logger Power Supply
The Logger does not include a power switch, but turns on automatically
whenever its power supply leads are connected to a voltage in its allowed
range. You can plug the Logger’s power supply leads into a standard wall
outlet (using the included adapter cord), or you can connect them directly to
the power network under test (in parallel with the test leads) if there is no
convenient wall outlet (only if the voltage at the test leads is below 660V
RMS.)
Logging Functions
The Logger monitors power quality and locates disturbances in low and
medium voltage distribution networks. It measures up to 3 voltages and
4 currents. Logged values are saved in your choice of sequential averaging
periods. You graphically or numerically evaluated measured values with PQ
Log.
The Logger has two types of logging functions: logging function A
(Advanced) and logging function P (Power). Function A is the full set of
parameters, and function P provides logging capability optimized for load
studies and basic power logging. Function P contains every parameter in
Function A except voltage and current harmonics and interharmonics.
Logging function P allows longer logging periods because it does not save
harmonics values.
