The Kyoritsu 2040 digital clamp-meter is an average-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 600A (amperes). The clamp has two jaws that can close around an electrical conductor up to 33mm (1.3 inches) in diameter to measure current without touching or interrupting the circuit. A set of test leads is included for measuring AC and DC (direct current) voltage to 600V, frequency to 10kHz (kilohertz), and resistance to 60MΩ (megohms). Frequency can also be measured with the clamp. The meter has a rotary switch to select the property to measure, and a 6,039-count LCD that shows the reading numerically and in a 60-segment bar graph.The meter's relative function allows a measurement to be set as a reference value and displays subsequent measurements as a negative or positive deviation from that value. The minimum/maximum function tracks the lowest and highest readings for a property for as long as the function is engaged. To capture readings in tight spaces and aid documentation of readings, the data hold function keeps the most recent reading on the display after disconnecting from the circuit. A noncontact voltage (NCV) detector in the jaws senses voltage without making contact with the circuit and triggers a red LED when voltage exceeds 100V. 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 two 1.5V AAA batteries, and turns off automatically after 15 minutes of non-use to conserve battery life. It has a low-battery indicator that signals when the battery needs to be replaced.This average-sensing, also called average responding or mean value, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It is auto-ranging, so it automatically...
