Greenlee DML-430A Information The Greenlee DML-430A is a digital multimeter (DMM) that features a variety of measurement capabilities, including AC and DC voltage, AC and DC current, frequency, resistance, capacitance, and duty cycle of logic level signals. It also checks diodes and verifies continuity. The DML-430A meter features true RMS AC measurements, a relative zero mode, data hold mode, and an intelligent automatic power off. An optional optically isolated computer interface with software facilitates the recording of readings from the meter to a computer.
