The Fnirsi S1 digital multimeter measures AC and DC voltage, resistance, capacitance, frequency, and temperature. True RMS supports accurate measurements, while the LCD displays up to 10,000 counts and offers resolution from 0.001 V to 1 V.
It includes non-contact voltage detection (NCV), continuity testing with a buzzer, diode testing, and live wire detection. It measures automatically and features a flashlight and data hold. The rechargeable lithium-ion battery charges via USB-C.
