Uei Test Instruments TCM Trade Clamp Meter 400A

Product Description

The UEI TEST INSTRUMENTS TCM is a 400-amp entry-level clamp meter built for HVAC/R and general electrical service work. It handles standard diagnostic functions including resistance, capacitance, DC microamps, and temperature measurement, making it a capable everyday tool for field techs. Safety-rated at CAT IV 300 volts and CAT III 600 volts, and ETL-certified to IEC 61010-1 (3rd edition), the TCM meets the protection requirements expected on commercial and residential job sites. The kit ships with standard test leads, threaded alligator clips for hands-free testing, and a zippered carrying pouch.

The TCM is suited for HVAC/R technicians, electricians, and electrical service professionals working on residential and light commercial systems. Its 400-amp AC current range covers the load measurements most commonly encountered in HVAC compressor, motor, and circuit diagnostics. The included alligator clips allow hands-free measurements during live-circuit monitoring, a practical advantage when working alone in tight equipment spaces. This is a 2026 Commemorative USA 250 Year Anniversary Edition replacing the discontinued DL569.

Installation Notes

The TCM is a handheld test instrument and does not require installation. De-energize circuits before connecting test leads or alligator clips where safe and practical, and follow local electrical safety codes when working on live circuits. HVAC/R technicians should verify the meter range is appropriate for the circuit under test before taking measurements. Keep the meter and leads clear of conductors rated beyond the CAT IV 300V / CAT III 600V limits of this instrument.
