UNI-T UT677C is the model of the UNI-T UT677 series that can measure battery voltage up to 120 V; it assesses the condition of rechargeable batteries such as lead-acid and lithium types by measuring their internal resistance and voltage. Internal resistance is measured in 4 ranges from 0.000 mΩ to 3 Ω with the 1 kHz AC four-terminal method, with a best resolution of 1 µΩ. The voltage ranges are 0.000–±7 V (1 mV), 7–100.00 V (10 mV) and 100–120.00 V (100 mV), with an accuracy of ±0.2% fs ±10 dgt. The response time is 200 ms and the test time is 2 s; PASS/WARNING/FAIL thresholds can be preset, 500 sets of data are stored, and PC software and a Bluetooth app are supported. It has a 3.5″ colour screen and a 2600 mAh lithium battery, and weighs 674 g including the battery. The UT677 series is used in battery production, installation and maintenance; the UT677C measures battery voltage up to 120 V.
