Green clamp meter with wide jaws and digital display

KEHIPI

KEHIPI TCM-300A Inrush Clamp Meter 6000 Counts TRMS Green

SKU CH-TKTH-QHK66

Measures AC current up to 600 A with inrush capture plus AC/DC voltage, resistance, capacitance, temperature, diode, continuity.

  • Width11.8 in
  • Measures AC current up to 600 A without breaking the circuit
  • Captures motor inrush current from 5 to 600 A for startup diagnostics
  • Auto-ranging TRMS reads AC/DC voltage, resistance, capacitance, frequency and temperature
  • Non-contact voltage alert at the clamp tip for live-wire detection
  • 6000-count display with data-hold and 11.8 in width for bench or field use

Versatile Electrical Tester

The KEHIPI TCM-300A is a 6000-count TRMS clamp meter built for electricians, technicians and serious DIYers who need one instrument for AC current, AC/DC voltage, capacitance, resistance, diode, continuity, frequency, temperature and non-contact voltage detection. Smart and manual ranging modes let you match the tool to the task, whether you are troubleshooting a motor starter or verifying a household circuit. The 11.8 in width gives a comfortable grip for extended use.

Sustained Measurement Behaviour

Inrush capture locks onto motor start-up surges from 5 to 600 A in AC mode, showing the true peak rather than a momentary spike so you can size protection correctly. True-RMS conversion remains accurate on distorted waveforms common in variable-speed drives and electronic ballasts, preventing the under-reading that averages cause. Auto-ranging settles quickly between ranges, keeping the display stable during long monitoring sessions without manual range hunting.

Pre-Purchase Checks

Verify that the conductors you intend to clamp fit within the jaw opening, as the meter only measures a single isolated wire and cannot read through a complete multi-core cable. Confirm your test leads terminate in standard banana plugs for the INPUT and COM jacks supplied with the unit. Ensure the working environment stays within the meter’s rated voltage category for the circuits you plan to probe, and that you have a suitable temperature probe if temperature logging is required.

Questions about this item

How much heat or noise does the TCM-300A generate during extended inrush current testing on 600 A circuits?

The clamp meter uses passive magnetic sensing with no active cooling, so it produces no audible noise and negligible heat even during prolonged 600 A inrush measurements.

Which test leads and power source must I already own to operate the TCM-300A for AC/DC voltage and resistance functions?

The meter includes red and black test leads that plug into the INPUT and COM jacks, and it runs on internal batteries — no external power supply is required.

Will the 11.8 in jaw opening fit around the same conductors I currently measure with my older clamp meter?

The 11.8 in jaw width determines the maximum conductor diameter; compare that dimension with your existing cables to confirm fit before purchase.
