Product Number: TA203
Diagnosing modern vehicle electrical systems demands a multimeter that goes well beyond basic voltage readings. The Sealey TA203 is a 15-function digital automotive multimeter built for workshop use, featuring an extra-large, high-contrast LCD with a 36mm digital read-out, bar graph display, and backlight for clear readings in all conditions. A dedicated millisecond pulse-width function enables accurate measurement of fuel injection systems, while the bar graph is essential for correctly testing lambda sensors two capabilities that set this metre apart from general-purpose units. It handles AC and DC voltage up to 1000V and 750V respectively, AC and DC current up to 20A, resistance, capacitance, frequency, duty cycle, period, dwell angle across 1 to 12 cylinders, and engine RPM for both 2-stroke and 4-stroke engines including DIS systems. Auto-ranging, data-hold, and auto-power-off keep operation efficient. The durable case includes probe storage, an integral stand, and is built for the toughest workshop conditions. Supplied with an inductive coupler with adjustable sensitivity, test leads with probe and clip, thermocouple, USB interface cable, and Windows ME/XP/Vista compatible software for downloading data to PC.
