The Hioki 3282 digital clamp-meter is a true RMS sensing, auto-ranging multimeter for measuring current, voltage, frequency, and resistance in electrical testing applications. It has a clamp that measures AC (alternating current) to 1,000A (amperes). The clamp has two jaws that can close around an electrical conductor up to 46mm (1.81 inches) in diameter to measure current without touching or interrupting the circuit. A set of test leads is included for measuring AC voltage to 600V, frequency to 1,000Hz (hertz), and resistance to 10k? (kilohms). The meter has a rotary switch to select the property to measure, and a 3,000-count LCD that shows the reading numerically and in a 35-segment bar graph. The crest factor function uses a 1.00 to 5.00 scale to measure the quality of an AC signal and its ability to generate a particular voltage or current. The record function displays the maximum, minimum, and average readings for a property after the function is engaged. 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 9V 6F22 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.
This true RMS (root mean square) sensing meter provides accurate readings when measuring linear or non-linear loads, regardless of the waveform. It is auto-ranging, so it automatically selects the appropriate operating range for the property being measured. Accuracy and resolution specifications vary according to the range being measured. The meter meets EN (European Standard) safety standard 61010, and is rated for CAT (category) IV installations up to 600V, which covers equipment at the origin of the installation, such as electricity meters and primary over-current protection equipment. It has CE (European Conformity) marking. The unit comes with a carrying case.
