OTC 3505A 100 Series Autoranging Automotive Multimeter, 12-Function Vehicle Diagnostic Meter
- The OTC 3505A is a 100 Series autoranging automotive multimeter designed for diagnosing vehicle electrical systems. It combines standard multimeter functions with engine control tests and includes leads, clamp, and temperature probe.
- Features:
- Auto and manual ranging modes across voltage, current, resistance, and frequency
- Capacitance, continuity, diode, and resistance tests for component-level diagnostics
- Vehicle-specific tests: RPM clamp, dwell angle, O? cross count, injector pulse width, and duty cycle
- Data hold, min/max recording, relative mode to subtract lead resistance, fused 10 A DC current input
