What do you know about digital multimeters?
Digital multimeter, as the name suggests, its working principle is mainly to detect and analyze signals based on digital circuits, and then provide LCD display through analog-to-digital converters.
Although the digital multimeter is a relatively complicated electronic measurement tool, if it is operated correctly according to the manual, pays attention to the general precautions, and maintains a good use environment, the service life and accuracy of the instrument will be greatly improved and stabilized. The digital multimeter uses a liquid crystal display as a reading device, which has the characteristics of high measurement accuracy, safe and reliable use. It has many models and varieties, and the measurement is very simple.
The digital multimeter mainly includes: DC voltage, DC current, AC voltage, AC current, resistance, circuit continuity test, diode test and other common measurement functions; with the development of electronic technology, the multimeter has many application functions: data storage, data Transmission, oscilloscope, etc.: Some of them are developed into professional application fields: power meter, leakage current tester, insulation resistance tester for electric power test, infrared thermometer used in industrial and mining industries, noise meter and anemometer for environmental test Wait.
Let me introduce our DT-112 pocket digital multimeter to you.
1. Automatic range; data hold, maximum value hold, automatic shutdown and low battery indication.
2. In terms of accuracy and resolution, digital display has a good advantage, and the measured value can be displayed with three or more digits.
3. The analog pointer is slightly inferior in accuracy and resolution. Because you have to estimate the position of the pointer.
4. The bar graph shows the change and trend of the signal like an analog pointer. But it's more durable and takes less damage.
Features of DT-112 Pocket Digital Multimeter:
1. 2000-bit liquid crystal digital LCD display;
2. Relative value mode;
3. Automatic range;
4. Data hold, maximum hold, auto power off and low battery indication.
Value hold button
The value hold function can make the meter lock a current measurement value for future reference
1. Press the "HOLD" button to lock the displayed value, and the "HOLD" indicator will appear on the display.
2. Press the “HOLD” button again to return to normal operation.
Automatic shut-down
1. To save power, the display will automatically turn off after 15 minutes.
2. Press the SELECT button to open the display.
To cancel automatic shutdown, turn the function selection knob to the off position. Press and hold the SELECT button and turn the function selection knob to the desired position, release the SELECT button after 3 seconds.
