The DVM should be able to read Volts and milliAmps DC. Besides the usual sources, a suitable DVM can be found in the hardware stores, auto parts stores, and department stores.
One should also know how to use the DVM. It is possible to damage the loop, the DVM, or yourself by using it improperly. Voltage is measured by attaching the DVM leads across the device, essentially attaching the DVM in parallel with the device. Current is measured by attaching the DVM in series with the circuit. The loop wire must be disconnected, and the DVM attached into the circuit to cause all the current to run through the DVM.
A malfunctioning 4/20mA loop can be caused by many things. The first thing to do is determine where the problem is. Problems can be caused by power, wiring, or loop device issues. If the loop does not appear to function in any manner then one should first check the power and wiring. If it appears that the loop is functioning in some manner then the nature of the malfunction becomes important.
