The draper dmm301 is an automotive digital multimeter designed for professional diagnostics and electrical testing on vehicle systems. This versatile instrument combines standard electrical testing capabilities with specialist automotive functions, making it ideal for mechanics, auto electricians and mobile diagnostics technicians working on modern vehicles. Offering both auto and manual ranging modes, this multimeter handles a comprehensive range of electrical measurements including ac and dc voltage up to 600v, current testing up to 10a, resistance measurement up to 60mo, and capacitance testing. The integrated temperature probe extends measurement capability from -20 c to 1000 c, whilst the backlit lcd screen ensures clear readings in dimly lit workshop environments or under vehicle bonnets. What distinguishes this model for automotive applications is its specialist diagnostic functions. The dwell function accommodates 4, 6 and 8-cylinder engine configurations for ignition timing analysis, whilst the tachometer tach measures engine rpm across a wide range. The included inductive clamp enables non-contact current measurement, and the duty ratio function assists with testing pulse-width modulated circuits common in modern vehicle electronics. Practical features such as data hold, max value capture, continuity buzzer and automatic power-off enhance usability during diagnostic work. Features and benefits: auto and manual ranging for flexible measurement across multiple ele...
