The Reed C-212 digital clamp-meter is a true RMS sensing, manual- and auto-ranging multimeter for measuring current, voltage, 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 40mm (1.57 inches) in diameter to measure current without touching or interrupting the circuit. A set of test leads is included for measuring AC voltage to 750(V, DC voltage to 1,000V, voltage frequency to 10kHz (kilohertz), and resistance to 4,000Ω (ohms). Frequency of the current can be measured with the clamp. The meter has a rotary switch to select the property to measure, and a 3,999-count LCD that shows readings numerically and in a 42-segment bar graph. Its relative function allows a measurement to be set as a reference value, and it displays the subsequent measurements as positive or negative deviations from that value. The peak hold function records the maximum and minimum readings for voltage and current during a 1ms (millisecond) sampling time. The maximum/minimum function tracks the highest and lowest readings for a property for as long as 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, 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 30 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 waveform. It has two ranging modes: manual, which allows the user to select the operating range, and auto, which automatically selects th...
