ARMADA TECHNOLOGIES PRO-93 TRUE RMS 2-WIRE MILLIAMP CLAMP MULTIMETER:
2-Wire irrigation systems require a different set of tools to diagnose electrical problems. One of these is a clamp multimeter that can measure milliamps. Decoders in a 2-Wire system run on milliamp sized current. Without the capability to measure whether or not the right amount of current is being used, your flying blind.
The Armada Pro93 True RMS milliamp clamp multimeter is perfect for the job. By utilizing the Pro93's sensitive AC clamp, which appear as a loop at the top of the meter, a technician can determine the general location of where a ground voltage leak is occurring in a 2-Wire system. The Pro93 measures AC amp current leakage down to 10 microamps simply by using the integrated clamp over one conductor or the 2-Wire cable in question. This is done at various points in the system, usually right at the decoder. Any unusual drop in the milliamp current indicates a problem.
The Pro93 utilizes True RMS technology. True RMS stands for Root Mean Squared, an obscure term if you are not an electrical engineer. In practice, it means that the Pro93 uses a more accurate measuring system than conventional clamp multimeters.
In addition to milliamp readings, VAC, VDC, Ohms, and HZ measurements are available. All utilize a built-in auto ranging function for easy use. Included with the Pro93 are 2 AAA batteries and a soft shell carrying case. The Pro93 makes diagnosing cable faults in 2-Wire systems simple and easy to perform.
