The FLIR CM46 clamp meter is designed for commercial and residential electricians. Featuring both AC/DC measurement, the meter is equipped with a bright backlit display for use inside electrical panels. Accu-Tip™ technology delivers amperage measurements on smaller-gauged wires more accurately — to a tenth of a digit. The meter also offers MAX/MIN/AVG recording; measures DCµA, temperature, capacitance, and frequency; and has electrical field detection to help you determine voltage presence and relative strength of the field.
