Product Description

The Reed ST-3347 digital clamp-meter with temperature probe is a true RMS sensing, auto-ranging multimeter for measuring current, voltage, capacitance, frequency, 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 30mm (1.2 inches) in diameter to measure current without touching or interrupting the circuit. A set of test leads is included for measuring AC and DC voltage to 600V, capacitance to 40μF (microfarads), frequency to 10MHz (megahertz), and resistance to 40MΩ (megohms). The meter comes with a K-type thermocouple probe that measures temperatures up to 1,000 degrees C (1,832 degrees F). It has a rotary switch to select the property to measure and a 4,000-count LCD that shows readings numerically and in a 40-segment bar graph. The peak hold function records the maximum and minimum readings for voltage and current. 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, and a diode check detects whether a circuit's diodes are working properly. The unit operates on a single 9V battery, and turns off automatically after 20 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 IEC (International Electrotechnical Commission) safety standard 61010-1 and is rated for CAT (category) III installations to 600V, which covers equipment in fixed installations, such as switches in the fixed installation and some industrial equipment that is permanently connected to the fixed installation. It comes with a soft carrying case.

Clamp-meters, also called clamp-on meters, have two jaws that fit around a conductor to measure electrical current without cutting through wires, or touching or interrupting the electrical circuit. Available in handheld or benchtop models, clamp-meters diagnose problems in electrical equipment, wiring, and power supplies. All clamp-meters test for current. Some come with test leads and inputs for measuring voltage, capacitance, and resistance. They display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltage. Safety ratings are based on International Electrotechnical Commission (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.

Reed Instruments manufactures test and measurement equipment such as pressure gauges, electrical testers, temperature and humidity instrumentation, and inspection instruments. The company, founded in 2004, is headquartered in Wilmington, NC.
