Check the case before use. Do not use the meter with a damaged case. Check for cracks or lack of plastic parts. Please pay special attention to the insulation layer of the test leads and connecting wires. Do not touch the metal part of the test lead probe with your fingers when using the test lead.2. Do not operate in high temperature, humidity, rain, flammable and explosive environment and the instrument is wet.3. Never apply a voltage/current exceeding the maximum limit that the meter can withstand to the meter.
