Wide test range: - Wide detection range from 0,8 V do 100 V DC makes,that the device is suitable do different tests of vehicle circuits,such as test car fuses,test cables, test battery and ACC system,so you can more easily check for problems in the vehicle. The device can automatically identify the positive and negative poles of the battery, and the “-” sign indicates the negative pole before reading. The data retention button allows you to keep the data unchanged on the screen to preserve the data. Smart Mode: In standard intelligent measurement mode, as long as the probe touches the source or resistor, ona can automatically detect the current measurement signal (solid voltage, polarity, resistance and continuity). Easy to use: - When the resistance is lower than 50Ω, the built-in buzzer can remind you of this. Or if the DC voltage is higher than 100V, “OL” will be displayed on the screen. The long spring ma negative clamp and probe cover, so you can safely operate and store it separately. Backlit LCD display and more: - Featuring a backlit LCD display and flashlight, it allows for clearer reading and precise operation in dark areas. You can briefly press the light button to turn the screen backlight on/off, and long press to turn the flashlight on/off.
