【KYORITSU】High Impedance Probe TNW-411・412

High Impedance Probe TNW-411・412

The TNW-411 and TNW-412 are high-impedance probes that conform to CISPR (International Special Committee on Radio Interference), EN, and Electrical Appliance and Material Safety Law regulations and are used for measuring the disturbance voltage leaking from a disturbance source onto an external connecting conductor in the frequency range 9 kHz to 30 MHz. The input resistance of the probe is 1.5 kΩ and the stray capacitance (Cp) is less than 10 μF.
Additionally, by registering the correction factors of this device into radiation receiver manufactured by Kyoritsu Electronic Industry (KNM-2401, KNM-2402, KNM-2403, and KNM-S243), automatic addition can be performed through key operations, enabling direct reading measurement of interference voltage.
