Unlike the EZ Cube that auto-ranges for voltage and allows the user to specify the maximum current on its control panel, the EZMeter must be ordered specifically for the type of electrical system where it will be used. Hover the mouse on Applications in the main menu and choose the type of location. You will be presented a description of the most common meters for that use.
Beside the standard meters that can be purchased online, there are hundreds of possible combinations for different voltages, current capacities, 2-wire, 3-wire, 4-wire, single or three phase, wye or delta. There are also many options for automatic meter reading, pulse or serial output, Modbus or Plus protocol, different pulse lengths, baud rates and parity. See the menu on the left for specific details. The Specifications & Part Numbers link will allow you to choose all the parameters then give you a part number. You can also download a pdf with specifications for that particular meter.
