current Probe (AC/DC) Technical Specifications Doble’s Current Probe (Part number 401-0055) is a tool that aids in the measurement of current signals when using the Recording feature of Doble’s Transwin program. This probe converts the current in the conductor that it encircles into an equivalent voltage signal. This equivalent voltage signal when applied to the logic input of the F6150 instrument gets translated into appropriate amperes by the Transwin program.
