CEM DT-397 clamp meter for electrician

CEM DT-397 clamp meter for electrician,
AC/DC 600A True RMS, with NCV

Category: Clamp Meters

For electricians, DT-397 clamp meter is an important alternative to a standard multimeter when working on live, high-current electrical systems.

Such as offices, retail stores, warehouses, and HVAC systems, electricians often work with:

High-voltage systems, such as 277/480V lighting and 208/120V electrical panels
Large motor-driven equipment like fans, pumps, and compressors
Multiple parallel power feeders
Crowded electrical panels with limited working space

A clamp meter allows electricians to safely measure:

AC/DC current without shutting down equipment
Voltage using test leads on most models
Resistance and circuit continuity
Frequency, capacitance, and temperature on advanced models

In order to meet the requirements for electrician, this clamp meter covers many useful features, like True RMS,

safety rating CAT III 1000V / CAT IV 600V, 600A AC current capacity , Voltage up to 1000V, Inrush current, Low-pass filter.

Safety:
IEC61010-1 CAT III 1000V / CAT IV 600V
UL, CSA, and TÜV listed for maximum safety and global compliance

Applications:
-- Load balancing – Clamp each phase leg of a 3-phase panel to see imbalances.
-- Motor troubleshooting – Measure running vs. nameplate FLA; check inrush on startup.
-- Paralleled conductors – Verify equal current sharing.
-- HVAC/R – Compressor current, heater amps, blower motor load.
-- Identifying live circuits – Quick check of multiple conduits or feeders.
-- Leakage current – Clamp around both hot and neutral together; any reading indicates ground fault.

Features

tool application	electrician work, e.g. VFDs, heavy motor loads, or general distribution work
safety	Auto discharge of voltage test signal; IEC/EN 61010: CAT III 1000V / CAT IV 600V, safety at main panels and feeders

current Range	AC / DC up to 600A plenty for most commercial feeders (100A–400A common)
Voltage Range	up to 1000V
Jaw Opening	Φ 34 mm Thin, small jaws, Fits around tightly packed conductors in panels

functions	Measurement of AC/DC voltage, current, resistance, capacitance, frequency, temperature, duty cycle, and continuity, etc.
True RMS	Industrial systems often use non-linear loads (VFDs, inverters, motors). True RMS ensures accurate readings even with distorted waveforms
Low-pass filter	Removes noise from VFDs (even if not common in pure distro, still useful when mixed loads exist)
Inrush current	It captures that micro-second spike in current to determine if a motor is mechanically stuck or if the start capacitor is failing.
IR Temperature	embeded Non-contact infrared thermometer – Measures surface temperature from a distance

Ease of use	Modern design, Easy-to-Use
Backlight for LCD, Flashlight	dim electrical rooms, Illuminates dark panel interiors
certification	CE, TüV certification
