The ALTA Wireless Resistive Bridge Meter uses two wires, red(1) and black(4), to excite a resistor bridge, thus providing a reference voltage for the measurement. Two additional wires, white(2) and yellow(3), measure the differential voltage across this bridge in mV/V. This meter contains a Programmable Gain Amplifier (PGA) and can be set to values between 1X and 128X, essentially increasing the measurement's resolution and reducing measurement error. The 50 and 60 Hz filters are also programmable.

Thresholds can be set so that when the output gets above or below a user-defined threshold, a wireless communication is immediately sent to the gateway. The gateway will immediately attempt to securely send the message to iMonnit or other approved data services.
