Product introduction:
This meter is used to measure the voltage of the DC power supply and has the function of high and low voltage alarm; it can be directly connected to the power supply to be measured without power supply. There are two buttons behind the meter to set the alarm voltage value; the pressure measurement range of the meter is 3.6V~ 50V, the alarm setting range is 4.5V~50V; it has high-precision pressure measurement, and the accuracy can reach 0.1V, which is comparable to the imported meter. The digital tube uses a high-brightness digital tube, and a variety of colors are available.
How to set:
1. Connect the power supply of the voltage to be measured as shown in the figure above, and distinguish the positive and negative poles; (red positive and black negative)
2. Long press the up key "+" when the screen number is flashing, press the "+" "-" key to set the upper limit voltage alarm value you want, and wait 5 seconds after setting, the system automatically saves the data.
3. Long press the adjustment key "-" when the screen number is flashing, press the "+" and "-" keys to set the lower limit voltage alarm value you want. After setting, wait 5 seconds, the system automatically saves the data.
4. Press the "+" and "-" keys at the same time for 5 seconds, when the screen displays 888, the factory restoration is complete.
