Detailed Product Overview

The 3288-20 clamp meter measures AC and DC current with True RMS evaluation up to 1000 A. With current ranges of 100 A and 1000 A, the instrument covers typical load currents in electrical installations as well as higher currents in machines and equipment. True RMS evaluation enables accurate current measurement even with non-sinusoidal waveforms such as those produced by inverters, switching power supplies and electronic loads.

Current is measured using the clamp, allowing measurements on conductors without opening the circuit. The clamp accommodates insulated conductors up to 35 mm in diameter.

Additional measurement functions

In addition to current measurement, the instrument supports voltage measurements up to 600 V AC/DC as well as resistance measurement and continuity testing using test leads. A zero adjustment function is available for DC current measurement to compensate sensor offset before measurement. The instrument supports automatic and manual range selection.

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 attached to the rear of the instrument, enabling one handed operation while both probe tips are placed on the measurement points.

Safety and application range

The safety category depends on the measurement method. Current measurement using the clamp is rated for CAT III 600 V. Voltage and resistance measurements using test leads are rated for CAT III 300 V or CAT II 600 V.

This makes the instrument suitable for current measurements in electrical installations within buildings, for example in distribution panels, machine circuits or industrial power circuits. Like all HIOKI clamp meters, clamp multimeters and current probes, the 3288-20 is manufactured in HIOKI’s own production facilities in Japan
