HIOKI 3288-20 True RMS AC/DC Clamp Meter | Solar & Industrial

The HIOKI 3288-20 AC/DC clamp meter combines True RMS current measurement on both AC and DC circuits in a single, portable instrument. DC current measurement to 500 A makes it particularly valuable for solar PV installations, battery systems, and DC distribution — applications where standard AC-only clamp meters fall short.

The inrush current capture function records the high transient currents drawn by motors and transformers at start-up — data that is critical for setting protective relay trip curves and verifying correct motor starter operation. True RMS measurement ensures accuracy on the distorted waveforms produced by inverters, variable speed drives, and other non-linear loads encountered in modern industrial electrical systems.

Key Features of the HIOKI 3288-20

• DC measurement capability makes it suitable for solar PV and battery storage applications
• True RMS engine gives accurate readings on distorted waveforms from inverters and VSDs
• Inrush capture records motor start-up peaks for protective relay setting and verification
• Covers both AC and DC circuits — reduces the number of instruments needed on site
• Backlit display aids readability in dimly lit switchboard and plant environments
