The Kyoritsu KEW 2117R is a True RMS digital AC clamp meter designed for industrial and electrical maintenance applications. It features auto-ranging measurement of AC current up to 1000A, AC/DC voltage up to 600V, and resistance up to 600 kΩ. The large conductor jaw accommodates cables up to 33 mm diameter. An ergonomic over-molded body allows comfortable one-hand operation, while safety features include CAT IV 300V / CAT III 600V ratings per IEC 61010-1. Additional functions include non-contact voltage (NCV) LED detection, data hold, auto power off (10 minutes), and audible continuity buzzer. Powered by two AAA batteries with approximately 170 hours of battery life. Supplied with 7066A test leads, carrying case, batteries, and instruction manual. Made in Japan. Typical applications include electrical panel troubleshooting, motor current measurement, HVAC maintenance, and power quality surveys.
Q: What is the maximum AC current this clamp meter can measure?
The KEW 2117R measures AC current up to 1000A in auto-ranging mode, with True RMS technology for accurate readings on non-sinusoidal waveforms.
Q: What is the jaw opening size?
The clamp jaw accommodates conductors up to 33 mm in diameter, suitable for most industrial power cables.
Q: Is this clamp meter True RMS?
Yes, True RMS measurement ensures accurate readings even on distorted or non-sinusoidal waveforms common in industrial environments with VFDs and switching power supplies.
Q: What safety category does it comply with?
The KEW 2117R is rated CAT IV 300V and CAT III 600V per IEC 61010-1, making it safe for measurements at the service entrance and distribution panels.
Q: How long do the batteries last?
Battery life is approximately 170 hours of continuous operation with the NCV LED off, powered by two standard AAA batteries.
Q: Does the meter have an auto power-off feature?
Yes, it automatically powers off after approximately 10 minutes of inactivity to conserve battery life.
Q: What accessories are included?
The meter comes with 7066A test leads, a 9079 carrying case, two AAA batteries, and an instruction manual.
Q: What is the accuracy of the AC current measurement?
AC current accuracy is ±1.5% of reading ±4 digits for 45-65 Hz measurements, and ±2.0% ±5 digits for 40 Hz to 1 kHz bandwidth.
