The PeakTech 1635 is an affordable and practical clamp meter for measuring small direct and alternating currents up to 2 A with a resolution of 1 mA. With clamp measurement, electrical conductors do not need to be disconnected to perform a current measurement. The device measures current indirectly through the surrounding magnetic field, meaning it measures contactlessly when the clamp jaws encircle the live conductor (single wire). Since the sum of all incoming and outgoing currents neutralizes the magnetic field, leakage current can be measured by encircling all wires of a cable. In the automotive sector, this measuring device is ideal for capturing discharge currents of the car battery with the ignition turned off, allowing for quick and reliable identification of faults. In addition to measuring small currents, the PeakTech 1635 can also measure larger direct and alternating currents up to 80 A with a resolution of 0.1 A, making it suitable for use in hobbies, crafts, and industry.
