Reminder: The cable pen is purchased separately, and the delivery does not include the multimeter equipment. Each device includes a multimeter and a cable pen. Product description: The FS8233 smart multimeter has the size of a palm, a large 4.7-inch LCD display, auto range, true effective value, overload protection, shockproof silicone sleeve and audible NCV alarm. It is very portable and suitable for the maintenance of automobiles, electronic products, household appliances, HVAC, etc. Feature: Multimeter: Measure AC/DC current, AC/DC voltage, non-contact AC voltage (NCV) detection, live/neutral detection, resistance, diode, capacitance, temperature and frequency. Loud beeping sound: Once AC voltage is detected, the NCV sensor and the charged/neutral line detector will emit audible and visual alarms. Easy to read: The 4.7-inch LCD display with backlight allows you to view the readings clearly even in dim light. Easy to use: Provide you with automatic range and manual range modes, bringing an extremely simple experience. Safe and reliable: With overload protection and 1000V, 10A test line, it is safe and reliable to use. Durable: Anti-vibration and non-slip silicone sheath can effectively protect the equipment from damage. Ultra-portable: With dimensions of 5.6 x 3 x 0.9 inches, the palm-sized multimeter is small enough to be held in your hand or put in your pocket, making it easy to carry around. Auto power off: It will automatically power off if there is no operation within 15 minutes, which helps to save battery power. More functions: with data retention, flashlight, Celsius/Fahrenheit and other functions. notes: *For safety, please read the user manual carefully before use. *Batteries not included.
