The Multi Tester, a classic auto-ranging digital multimeter, is one of Mastfuyi's offerings. It boasts high performance, high reliability, and a compact handheld design with 3 1/2 digits. This versatile instrument can measure a range of functions, including AC and DC voltage, AC and DC current, resistance, frequency, diode, and continuity test.

The Auto Range & LCD Display feature of the Multi Tester provides automatic range selection, 2/3 readings per second, and 2,000 active counts. The backlit LCD display ensures easy viewing in dimly lit areas, and the large screen enables quick reading.

The Continuity test & Over-Range Indication function is another notable feature. If the measured line resistance is less than 100Ω, the multimeter's buzzer will sound to alert the user. Additionally, if the positive and negative poles are reversed when measuring a diode, the display will show "OL," and if the measured current is out of range, the dial will display "OL."

The Overload & Case Protection of the Multi Tester is designed for safety. Two fuses on the internal circuit board (F250mA/250V and F10A/250V) and two PTC thermistors protect the circuit to prevent damage from incorrect measurements. Furthermore, the two-part injection molding plus rubber sleeve provides protection against electric shock during use.

The NCV (Non-Contact Voltage) feature allows users to detect the presence of AC voltage by simply placing the top of the multimeter near a conductor. If the AC voltage is greater than 90V (RMS), the meter's background light will flash, accompanied by a buzzer sound.

The Data Hold function enables users to fix the measurement reading when it is unstable, facilitating easy reading and recording. The Automatic shutdown feature turns off the multimeter after 15 minutes of inactivity, conserving the power for the next use.

The Backlight function is also included, allowing users to turn on the backlight for 15 seconds by pressing the BACKLIGHT button for 2 seconds, making it easier to read in the dark.

The Multi Tester package includes a classic digital multimeter, a 9V battery, a user manual, and two test leads. Mastfuyi offers a 48-month unconditional warranty and lifetime after-sales service, ensuring customer satisfaction.
