(shut-off capacity 10 kA) Protectiondevice Current limiting resistor (5 Ω) COM G Dust-proof and water-proof construction (IP54) G Polarized terminal design prevents incorrect insertion of test leads G Internal current-limiting resistor and fuse protect against operating errors and catastrophic failures protect against short-circuit conditions in the unlikely event of catastrophic failure of the tester circuit: short-circuit current is limited until interruption by the fuse, rated for up to 10 kA. G Safe and simple AC load current measurement by optional CLAMP-ON PROBE G Option Set the clamp range to match the range of the 3255-50 9010, 9018 In addition to internal circuitry to protect against connection errors during use, the current-limiting resistor and fast-blow fuse 325550E2-3XB-05U Printed in JapanAll information correct as of Oct 3, 2003.
