Quantity:

* Full HF coverage 1 to 30MHz * Low interaction with item to be measured * Accepts cables up to 12.7mm * Reads true RF current * 5 ranges from 30mA to 3A FSD * 6th range with variable sensitivity * Battery saver * Long battery life * Meter only draws 3mA * Rugged all aluminium case * Size 64 x 140 x 38mm
RF Current Meter with sense coil that simply snaps over wires and cables will accurately measre actual RF current flowing in antenna elements, radials, ground wires and on the outside of coaGreat for fast measurements on its easy-to-read meter. Select from five ranges to measure actual RF current from 30mA to 3A FSD. A sixth range has a variable sensitivity control fro quick, fast checks. At maximum sensitivity, RF currents of 1mA or less will yield a usable meter deflection. This function is especially useful for tracking RFI pickup on household wiring and cables.
