Buyer Guidance
Choose the UNI-T UT105+ if you need automotive-specific RPM and dwell-angle measurements alongside conventional multimeter functions. For capacitance testing, pulse-width measurement, or a dedicated 12V battery-test function, compare the UT107+ before ordering.
Always use the correct input terminals and observe the meter’s specified current limits. The 20A range is limited to 10 seconds; do not exceed this duration.
