PRODUCT INTRODUCTION
MEWOI7470 clamp multimeter is a new generation of practical electrician measuring instrument with excellent performance carefully developed by our company. It is a three-and-a-half-digit portable digital clamp meter that can measure the maximum AC and DC 2000V voltage and AC 2000A current. Its circuit design of the whole machine is based on a new type of special MCU, and it has overload protection for all functions to protect the instrument from being burned out. The meter adopts button-type function switching, which has the characteristics of high reliability, high safety, and automatic range. With large-screen digital, data hold, undervoltage prompt, automatic shutdown function, true effective value measurement can accurately measure variable frequency voltage, non-sine wave voltage, surge current can measure the effective value of surge current with a period of 80mS, suitable for measuring large motors , Compressor starting current. It can measure AC current, AC /DC voltage, resistance, capacitance, continuity test, diode forward voltage drop, LED operating voltage, and other parameters. The instrument is compact in structure, easy to operate and portable, and is an ideal tool for electrical measurement. It is especially suitable for the occasion of measuring large current and starting current. |
