Extech’s new 380260 Autoranging Digital Megohmmeter is a 1000V digital tester with an easy-to-read large dual backlit display. The unit features insulation resistance to 2000 MΩ as well as a low resistance function with continuity. A “lock power on” function allows hands-free operation, while a data-hold capability freezes the displayed reading. Extech Instruments, Waltham, MA.
