The Ameritec Model AM48 can do a variety of measurements. With its built-in dial capability on dial-up networks it can access a distant responder or a second AM48 for centralized 2-wire testing. You can use a single unit with an Ameritec responder for centralized loop back testing. Or, use two sets for a complete end-to-end test of 4-wire data lines. In addition, the AM48 now combined with the new AM440 Remote Test Partner™ is able to further enhance your testing capabilities. A single technician can test a circuit with an AM48, AM440 and a multi-meter. The AM48 can transmit to the AM440 and measure its signal and can take noise measurements. The combination of these two measuring instruments allows for DMM testing, including resistance testing and the measurements of both voltage and capacitance.
