The TITAN TN830L is a compact digital multimeter built for everyday diagnostic work on the repair bench. It reads DC and AC voltage, DC current, resistance, and temperature using a K-type thermocouple probe, with a 3.5-digit LCD that keeps values easy to read under workshop lighting. Technicians use it to check board voltage points, trace shorts with the continuity/diode test function, and confirm charging IC output before committing to a jumper or IC change. Runs on a single 9V battery, is small enough to keep in a tool pouch, and covers the basic electrical checks needed for dead phone and charging issue diagnosis. A dependable entry-level meter for GSM shops in Lahore, Karachi, and Islamabad.
