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)
FEATURES
A new sensor profile yields outstanding ease of use
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.
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.
