Features: Functions: This Mini-size digital instrument realizes AC/DC voltage AC current Resistance Audible Continuity Diode Temperature Measurements. Electricity Tester: It is an automatic which varies with AC current meter function. When AC current is measured it can only measure the null line or live line and it is only the line of a core. The power supply line of common electrical appliances in the home can not be measured because it contains many core wires. LED Light: Detect contactless as well as Capacitance Hz etc. The multimeter has a flashlight function which is convenient to find the line in the dim environment and can also be used as an emergency flashlight. Practical: Multifunctional meter can be used to measure AC current AC/DC voltage resistance capacitance frequency diode on-off bell live detection.
