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.
A new sensor profile yields outstanding ease of use.
True RMS measurement yields accurate display values even when measuring a distorted waveform, for example from an inverter-equipped device or switching power supply.
The waveform including harmonic components is calculated according to an RMS calculation formula and displayed.
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)
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.
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.
Regular maintenance and management are essential in order to keep electrical equipment in buildings and manufacturing plants working properly, and current and voltage measurement comprises an important part of that process. Hioki has long supplied customers with measuring instruments and clamp meters that are used in the field to perform such maintenance and management. In recent years, the decreasing size of distribution panels and other changes have led to increased wire density, placing in cables in such close proximity that older sensor designs are too large to fit between cables so that they can be applied to the cable being measured. The newly launched CM3289 features a lower-profile sensor with pointed jaws so that it can be more easily inserted between wires in confined spaces. Whereas the 3280-20F’s sensor measured 82 mm across in the open position, the CM3289’s sensor measures just 71 mm, a reduction of 11 mm.
