Methods for Using and Maintaining a Digital Multimeter
Note:
1. If the measured resistance value exceeds the maximum value of the selected range, it will display over range; For ranges greater than 1 megaohm, a higher range of "1" should be selected; Or higher resistance, it takes a few seconds for the reading to stabilize, which is normal.
2. When not connected properly, such as in an open circuit situation, the instrument displays "1";
Note:
1. If the measured voltage range is unknown Set the function switch to the maximum range and gradually lower it to the appropriate range.
2. If the monitor only displays "1", it indicates over range, and the function switch should be set to a higher range.
3. Do not input a voltage higher than 700V. It is possible to display higher voltage values, but there is a risk of damaging internal circuits.
4. When measuring high voltage, extra attention should be paid to avoiding electric shock.
Note:
1. If the measured voltage range is unknown Set the function switch to the maximum range and gradually lower it.
2. If the monitor only displays' 1 ', it indicates over range, and the function switch should be set to a higher range.
3. Do not measure voltages higher than 1000V. It is possible to display higher voltage values, but there is a risk of damaging internal circuits.
4. When measuring high voltage, extra attention should be paid to avoiding electric shock.
Note:
1. If the measured current range is unknown before use, set the function switch to the maximum range and gradually lower it.
2. If the monitor only displays "1", it indicates over range, and the function switch should be set to a higher range.
3. 20A range without fuse protection, measurement cannot exceed 15.
