The HIOKI RM3548-50 portable resistance meter measures resistance from microohms to megaohms for maintenance of motors, transformers, connections and bonding conductors. Four-wire measurement and offset-voltage compensation support repeatable low-resistance readings.
Configuration: Z3210 is included in the Wireless Kit only. The EV Kit adds a 9465-11 pin type lead, two Z5020 magnetic straps and an EV maintenance manual.
