This tester is a battery-powered, easy-to-operate, and safe handheld analog instrument. It offers high sensitivity of 10kohm/V on DC voltage ranges and 4.5kohm/V on AC voltage ranges. It provides accurate and reliable measurements for current, resistance, continuity, transistor, diode, and capacitance testing. It includes reliable overload protection through fuse and diodes. It is a practical instrument for use in garages, workshops, schools, and homes. Model: 5818 DC Voltage: 0.5/2.5/10/50/250/500/1000V 2.5% F.s. AC Voltage: 10/50/250/500/1000V 5.0% F.s.
