Using a digital clamp ammeter, the reading is more intuitive and the use is more convenient. The usage and precautions are basically the same as the pointer clamp ammeter. The following only introduces several common problems that may be encountered during use.
1. About range selection.
·When measuring, if the displayed number is too small, it means that the selected range is too large, you can switch to a lower range and measure again.
·If the overload symbol is displayed, it means that the selected range is too small, and it should be switched to a higher range and re-measured.
2. It is not possible to change the range during the measurement process. The wire under test should be withdrawn from the iron core jaw, or press and hold the "Function" key for 3s to turn off the digital clamp meter, and then change the range.
3. If you need to save the data, you can press the "Function" button during the measurement process, you can hear a beep sound, and the measurement data at this time will be automatically saved on the display.
4. When using a functional digital clamp meter to measure the resistance, AC voltage and DC voltage of the circuit, insert the test leads into the test lead jacks of the digital clamp meter, and set the range selection switch to "V~" (AC voltage) as required. Voltage), "V-" (DC voltage), "Ω" (resistance) and other gears, use two test pens to touch the measured object, and the LCD display will display the reading.
