Professional True RMS Clamp Meter

The CEM DT-3353 is a professional True RMS 1000A AC watt clamp meter designed for electricians and technicians who need accurate power measurements on single-phase and balanced three-phase systems. It provides reliable Watt, AC current, and voltage readings regardless of waveform distortion. The large dual LCD display with backlight ensures clear visibility in varied lighting conditions. A USB interface allows data transfer for further analysis.

Capacity and Headroom

The meter measures AC voltage across 15V, 100V, 300V, and 750V ranges with a basic accuracy of ±(1.2%+5). AC current is covered in 40A, 100A, 400A, and 1000A ranges, while the 55mm jaw opening accommodates large conductors. It records true power, apparent power, and power factor, storing up to 99 data sets manually. Auto-ranging and auto power-off simplify operation, though batteries are not included due to shipping restrictions.

Upgrade Path

This clamp meter replaces basic average-responding models that cannot handle non-linear loads or provide power factor analysis. The jump is worthwhile when troubleshooting variable frequency drives, electronic ballasts, or distorted waveforms where True RMS accuracy is essential. It is not suited for users who require DC current measurement, high-voltage testing beyond 750V AC, or integrated oscilloscope functions.

Highlights

  • Accurate readings on distorted waveforms with True RMS technology
  • Measure up to 1000A AC current across four ranges
  • Large dual LCD with backlight for clear visibility
  • Store and recall up to 99 measurement sets manually
  • Detect voltage without contact using built-in NCV function

Questions about this item

Will the 55 mm jaw opening fit around the same thick cables I use with my older clamp meter?

The jaw opens to 55 mm (2.16 inches), so it will accommodate any cable that fits within that diameter.

How can I verify the True RMS readings are accurate after I set up the DT-3353?

Compare the AC voltage and current readings against a known reference source; the basic accuracy for AC voltage is ±(1.2 % + 5 digits) and for AC current it is ±(1.2 % + 5 digits) on the 40 A to 1000 A ranges.

What accessories come in the box with the DT-3353 and what must I buy separately?

The meter ships without batteries and without an English user manual; you will need to purchase batteries locally and can request the manual from customer service after purchase.
