Clamp Multimeter Unit UT213C 400A — AC/DC Current Measurement, Digital Display

Clamp multimeter Unit UT213C 400A is a handheld electrical tester designed for non-contact current measurement and basic circuit diagnostics. The unit supports AC and DC current measurement up to 400 A via a clamp jaw and provides a digital display for reading voltage, resistance, continuity and diode test results. Compact housing and one-handed operation make it suitable for field service, HVAC checks and maintenance tasks where quick and safe current measurements are required.

Advantages

The clamp multimeter offers combined clamp and multimeter functions in a single handheld instrument, enabling fast switching between current measurement and other electrical tests. Its clamp design permits non-intrusive measurement of conductors without disconnecting circuits, reducing downtime and improving safety. A clear digital display presents readings for voltage, resistance and continuity, and the device includes diode test capability for component verification. The compact form factor and ergonomic jaw enhance usability in tight spaces.

Suitable for

• Measuring AC and DC current in electrical installations and machinery
• Voltage checks on circuits and equipment
• Resistance measurement and continuity testing for troubleshooting
• Diode testing during component diagnostics
• Field service technicians, electricians and HVAC maintenance

Key specifications

• Current measurement: AC and DC up to 400 A via clamp jaw
• Display: digital readout for numerical values
• Functions: voltage measurement, resistance measurement, continuity check, diode test
• Form factor: compact handheld design with ergonomic clamp
• Operation: one-handed clamp measurement for live conductors without direct contact

How to use

To measure current, open the clamp jaw and place it around a single conductor, then close the jaw and read the current value on the digital display. Select the appropriate function on the rotary switch or mode selector for voltage, resistance, continuity or diode testing. For voltage and resistance measurements, use the meter leads as indicated in the device manual and observe correct polarity when required. Ensure the device is set to the correct measurement range if manual range selection is needed and follow safe working practices when measuring live circuits.

Usage recommendations

Verify the meter function and condition before use and replace batteries as recommended by the manufacturer. When measuring current, clamp only one conductor at a time to ensure accurate readings. Observe all applicable safety standards and wear appropriate personal protective equipment when working on live electrical systems. Store the instrument in a dry, dust-free place and avoid exposure to extreme temperatures to maintain measurement accuracy.
