Kewtech KTD40 Digital Loop / PSC Tester 9906G

Uses the very latest in electronic design to produce a compact and feature packed test instrument. Tests for low and high current loop impedance. High current test reads true loop impedance, including the supply transformer reactance. Checks for 18 socket wiring conditions, including the very hazardous condition of a line / neutral reversal at the supply. Fully protected against accidental phase to phase connection. Instant readout of PFC/PSC available by means of a secondary button. Mains te
