Chapter 1 General Information
The PowerSmart+ Advanced Power Quality Meter is a compact, multi-
function, three-phase AC power-meter and power quality analyzer specially
designed to meet the requirements of users ranging from electrical panel
builders to substation operators.
Bright 3-row LED display provides easy local meter readings. The display
module is freely detachable and can be located at a distance of up to 1000
meters from the device.
