A wide variety of tools exist which serve such functions, ranging from simple pieces of material against which sizes can be measured to complex pieces of machinery. | '''Meter''' is a device used to make measurements. A wide variety of tools exist which serve such functions, ranging from simple pieces of material against which sizes can be measured to complex pieces of machinery. Energy meter combines highly accurate industrial grade split-core CTs and precision microprocessor based metering electronics to provide exceptional metering accuracy and greatly reduce the total metering system installed cost. The accuracy of the Energy Meter is plus or minus one percent of reading from two percent (2A with a 100 A CT) to one hundred percent of the current rating of the CT. | ||
If equipped with a communications board and connected to a MODBUS control/data acquisition system, the Energy Meter reports energy and power diagnostics variables such as kWh, kW, PF, kVAR, Volts, and amperes. | |||

===Meter Display=== | |||
The meter display provides valuable installation diagnostics. If the meter is installed and the CTs and voltage leads are not properly matched, the display gives the installer feedback as to what is wrong. The PowerLogic® Energy Meter comes in two different models: Basic and Extended Range. | |||
===Basic model=== | |||
The Basic model is a display meter designed for direct monitoring of 240/120 V single phase two wire and three wire services and 208Y/120 V three phase four wire services and is ideal for stand-alone metering applications. The standard IR communications port and Palm OS organizer compatibility provides a simple way to accurately acquire and report energy information. Information stored in the organizer can be synched to a PC in text format, which can easily be imported into applications such as Microsoft Excel. | |||
===Extended Range=== | |||
The Extended Range model provides an extended input voltage range for single to three phase wye connected services (120-480 Vac, auto-ranging), a pulse output for easy integration with control systems, and a phase loss output to help protect equipment. | |||
