The Testec is an active differential oscilloscope probe that enables a conventional oscilloscope to display and measure in-circuit waveforms that are referenced to high common-mode voltages. It is capable of safely measuring differential voltages up to ±1000V AC and 1400VAC/DC. It supports bandwidths up to 100MHz. Supplied with: Probe 4 x AA batteries 2 x Grabbers red & black Instruction manual Factory calibration certificate
