Description
The TES-3900 and TES-3901 Clamp Meter are professional-grade instruments built for technicians who require fast, stable, and reliable electrical measurements. Both models support high AC current measurement up to 999.9A, along with voltage, resistance, frequency, and continuity testing. The integrated LoZ voltage function effectively removes ghost voltages, ensuring more trustworthy readings during troubleshooting.
The TES-3901 True RMS model adds advanced capabilities for demanding environments. It provides True RMS measurement in AC and AC+DC modes, making it ideal for variable frequency drives and non-linear loads. Additional functions such as µA measurement for HVAC flame sensors, mV range for accessory interfacing, Crest Factor and Harmonic Ratio analysis, and a backlight LCD enhance usability in the field. With built-in Max/Min recording, memory recall, and motor inrush capture, both models deliver the performance required by electrical engineers, maintenance teams, and HVAC professionals.
