Large LCD: LCD with large digits easy to check the number. 3. Flashlight: With a flashlight, it can work in different environments. 4.Application: Widely used in electrical appliance repair,household appliance repair,home wiring engineering and so on. 5. Advantage: Ideal for commercial settings where it can handle the demands of a long workday, from the durable exterior to the wide range of heavy-duty capabilities. NOTE: Instructions for use: 1. When measuring DC voltage DCV, AC voltage ACV, tributary current, resistance, diode, battery position, the red pen is inserted into the VmA jack, and the black pen is inserted into the COM jack. 2. When the DC current is greater than 200mA, the red pen is inserted into the 10ADC black pen and inserted into the COM jack. The function switch sets the response range. 3. When measuring the triode HFE, insert the PNP tube or NPN tube into the corresponding E, B, C jacks, and put the function switch in the HFE position. This watch has full-featured, accurate and accurate height, simple to use, small and light, and can measure DC voltage, DC current, AC voltage, resistance, diode, triode, is a professional enthusiast and family of computer enthusiasts radio enthusiasts.
