Quantity: One Specifications: Measures AC and DC voltage, DC current, resistance, AF level, transistor parameters, load current, load voltage, capacitance, inductance. Excellent resolution factor of 2mV DC and resistance measurements extended from 0.2 to 20M. Series capacitor terminal (OUTPUT) blocks DC to measure only AC components. A large meter with 80mm pulse length, full sensitivity of 44uA. Fuse and diode protection. hFE 1000 measurement with optional TR connector. DC Voltage: 100m/500m/2.5/10/50/250V/1000V 4% f.s. AC Voltage: 10/50/250V/1000V 5% f.s. DCA: 100u/2.5m/25m/250mA 4%f.s. OHM: 2K/20K/200K/2M/20M 4% arc. Dcibel: -10~+62dB L1: 150u/1.5m/15m/150mA HFE: 0~1000 (with TR connector) Power Supply: R6 (1.5V)*2, 622F 9V*1 (not included). This is a slim instrument with the latest internal magnetic measuring structure. It features high sensitivity, light weight, compact structure, and good diamagnetic performance. The entire circuit is protected by fuses, and the measuring mechanism is also equipped with a silicon diode protector to safeguard the circuit and moving parts from damage during overload. The dial has a wide field of view and is equipped with a mirror to reduce parallax, ensuring clear and accurate readings. Circuit board components are gold-plated PCBs with clear lines and good contact performance. The boards are assembled in an easy-to-maintain card structure. Good quality product.
