Detailed Product Overview

The CM3289 clamp meter measures AC current in three ranges up to 1000 A using True RMS measurement. This enables accurate current measurements even when the waveform deviates from a pure sine wave, as commonly found in circuits with electronic loads, frequency converters or switching power supplies. The clamp accommodates conductors up to 33 mm in diameter and features an optimized clamp design that improves access to conductors in densely wired distribution panels. It is suitable for typical installation wiring and supply conductors used in electrical installations and power distribution systems.

In addition to AC current measurement, the instrument measures voltage up to 600 V AC/DC and provides resistance measurement and continuity testing. The safety ratings are CAT IV 300 V / CAT III 600 V for current measurement and CAT III 300 V for voltage measurement.

Test Leads and Flexible Current Sensor

Voltage, resistance and continuity measurements are performed using the included L9208 test leads. The optional 9209 Test Lead Holder allows one test lead to be fixed to the rear of the instrument during measurements. The L9208 test leads are compatible with the optional HIOKI accessories L4934 for temporary hands-free connection to conductors and terminals and L4933 for measurements at closely spaced contact points.

For measurements on larger conductors, the instrument can be used with the optional CT6280 Flexible Current Sensor. This extends AC current measurements up to 4200 A. The flexible sensor loop allows measurements on large conductors, busbars and cable bundles.

Designed for Field Use

The instrument is designed for field use and provides drop protection from a height of 1 m. The operating temperature range of −25 °C to 65 °C allows use in outdoor installations and demanding environments. The CM3289 is supplied with the 9398 carrying case for transport and storage. Like all HIOKI clamp meters, the instrument is manufactured in HIOKI’s own production facilities in Japan.
