More About this Item

This 4.5-digit meter is ideally suited for difficult tests in which a high level of accuracy is a necessity. Your choice of measurement method is selected with switches. Standard “DC” resistance checks can be made with the probes set to either polarity. The special “AC” resistance calculation uses a 40 Hz square wave for the test voltage. Low test voltages of the meter (100 µV max.) greatly reduce the chance that oxidation, corrosion, and contamination will be “punched through”, resulting in false readings. Used in production situations, the meter’s audible tone can be used to indicate resistance values below any selected reading. With a resolution of 1 µW, this meter has the performance necessary for the most demanding jobs.
