Clamp Meter Unit 600 A TrueRMS Model UT216B, digital current/voltage tester

Unit UT216B is a 600 A TrueRMS clamp meter designed for electricians and technicians who need reliable AC/DC current measurement and basic electrical diagnostics in a portable digital instrument. The clamp provides non-contact measurement of conductor current up to 600 A, while the meter also supports voltage, resistance and continuity checks. The compact handheld housing and clear digital display allow quick readings during troubleshooting, maintenance and field diagnostics.

Advantages

The clamp meter uses TrueRMS acquisition to provide accurate readings on non-sinusoidal waveforms and distorted loads. A 600 A clamp range enables measurement of high current circuits without breaking the conductor. The instrument combines current measurement with voltage, resistance and continuity functions in one device, reducing the need to carry multiple tools. Ergonomic design and a digital display improve usability in confined spaces and on-site work.

Suitable for

• Measuring AC and DC current in residential and light commercial installations
• Troubleshooting electrical circuits and verifying current draw
• Checking line and load voltage and basic resistance measurements
• Routine maintenance and field diagnostics of motors, panels and control circuits

Key specifications

• TrueRMS measurement for accurate AC readings on non-sinusoidal waveforms
• Clamp current range up to 600 A for AC and DC
• Voltage measurement capability for AC and DC circuits
• Resistance measurement and continuity check with audible indication
• Digital display for numerical readout and measurement mode indication
• Handheld, portable form factor suitable for field use

How to use

Place the clamp around a single conductor to measure current; ensure the conductor is centered in the jaw for best accuracy and avoid clamping around multiple conductors simultaneously. Select the appropriate measurement mode on the meter (AC/DC current, voltage, resistance or continuity) and observe the digital readout. For resistance and continuity checks, disconnect power from the circuit before testing. Follow standard safety procedures for working on live equipment and wear appropriate personal protective equipment when required.

Usage recommendations

Store the meter in a dry, temperature-stable environment and inspect the clamp jaws and test leads regularly for damage. Calibrate according to local regulations or the manufacturer’s schedule to maintain measurement accuracy. Use the TrueRMS function when measuring circuits with variable frequency drives, non-linear loads or distorted waveforms to obtain reliable current values.
