Testermeter-PT740-1A (150kHz,400A) Current probe
INTRODUCTION
Testermeter-PT740-1A - Quick, safe and simple AC/DC current measurement. - Adopts the Hall effect principle to measure 1400A DC and 1400A AC peak; It is suitable for power measurement and can measure RMS value in the case of DC interference.- Standard BNC interface, can be customized multimeter dedicated interface. - There are two power supply modes: battery powered by microcomputer control after 10 minutes of automatic shutdown, adaptor power supply without automatic shutdown function. | ||
