UT677A+/UT677C Battery Internal Resistance Meter
The UT677 series of devices is designed to assess the condition of rechargeable batteries, including lead-acid and lithium types, by measuring their internal resistance and voltage. Using the four-wire (Kelvin) method, the device accurately measures internal resistance by eliminating the resistance of connections and wires. Thanks to the storage and retrieval of measurement data, information messages, automatic shutdown and strong protection against interference, the device is indispensable for servicing and operating batteries or backup power systems.
