AC CLAMP METER

CM3289

Quickly clamp wires in even more confined spaces!

Hioki clamp meters are best-in-class measuring devices incorporating Hioki’ s expertise in current sensing technology. The CM3289 is a True RMS rectifying 1000A AC clamp meter that features a broad operating temperature range of -25° C to 65° C, thin and compact clamp core and optional flexible current sensor that you can attach to let you get into the tightest spots. CAT IV 300 V (Current) CAT III 600 V (Current) CAT III 300 V (Voltage) CAT II 600 V (Voltage) Key Features • New redesigned sensor for even easier clamping (CM3289) • Expanded -25 °C to 65 °C operating temperature range • Model CM3289: Measure even harmonic waveform components using the True RMS method • Model 3280-10F: Measure the fundamental waveform component using the average rectified method • Connect the CT6280 flexible sensor to measure up to 4199 A in thick or paired wires

Video introducing the AC Clamp Meter CM3289

The popular 3280-20F AC Clamp Meter has be redesigned with a thinner sensor to help you get into the tightest spaces. Watch this video to learn more.


Quickly clamp wires in even more confined spaces!

A new sensor profile yields outstanding ease of use


True RMS model capable of accurately measuring even distorted waveforms

The waveform including harmonic components is calculated according to an RMS calculation formula and displayed. True RMS measurement yields accurate display values even when measuring a distorted waveform, for example from an inverter-equipped device or switching power supply.


A pocket clamp meter that can use flexible sensors

When connected to an optional flexible current sensor*, the CM3289 can be used to measure the current flowing in pairs of wires or in tangled or complexly routed wires around which it was not possible to apply a clamp-on sensor in the past. *AC FLEXIBLE CURRENT SENSOR CT6280 (4200 A AC, Φ130 mm)


Essential for electrical work: A thin card tester that fits in the pocket with all the capabilities of a clamp meter

The CM3289 delivers all the functionality of a clamp meter and card tester in the form factor of the latter. In addition to current measurement, this single instrument delivers voltage measurement, continuity check, and resistance measurement functionality.


Rugged, portable design that’s drop-resistant

Despite its thin, compact design, the CM3289 has an operating temperature range of -25°C to 65°C and can withstand being dropped from a height of 1 m onto concrete. It’s engineered for use in tough environments.
