Mastering the Art of Soldering
Please take the time and read these operating instructions before use and retain them for
future reference. Failure to follow these instructions may lead to serious injury and damage
to property.
Safety notes
1. When measuring, do not enter a limit that exceeds the range.
2. Measure a safe value, 36V DC or 25V AC, to check whether the connections are correct,
whether the insulation is good to avoid the shock.
3. When changing the function and range, the test leads should leave the test point.
4. In the resistance mode, please do not add voltage to the input.
