Hioki 3288-20 Digital Clamp Meter

Hioki 3288-20 Digital Clamp Meter . The Hioki 3288-20 digital clamp-meter is a true RMS sensing, manual- and auto-ranging multimeter for measuring current, voltage, and resistance in electrical testing applications. It has a clamp that measures AC (alternating current) and DC (direct current) to 1,000A (amperes). The clamp has two jaws that can close around an electrical conductor up to 35mm (1.38 inches) in diameter to measure current without touching or interrupting the circuit. Each jaw can be opened can closed independently of the other and is 10mm (0.39 inches) thick to fit between narrowly spaced conductors. A set of test leads is included for measuring AC and DC voltage to 600V, and resistance to 42M? (megohms). The meter has a rotary switch to select the property to measure, and a 4,199-count LCD. To aid documentation of readings and capture readings in tight spaces, the data hold function keeps the most recent reading on the display after disconnecting from the circuit. A continuity buzzer confirms that the circuit conducts electricity. The unit operates on a single CR2032 battery, and turns off automatically after 10 minutes of non-use to conserve battery life. It has a low-battery indicator that signals when the battery needs to be replaced
