Remind:

Use the right input jack, function and range.

Do not take measurements that exceed the protection limit values indicated in the specifications

Do not touch the metal tips of the test leads when the meter is connected to the circuit to be measured.

Keep your fingers behind the probe barriers when taking a measurement with an effective voltage above 60V DC or 30V rms AC.

Do not take voltage measurement if the value between the terminals and earth ground exceeds 1000V.

Select the highest range if the value scale to be measured in the manual range is unknown.

Do not measure the resistance，capacitance, diode or continuity of live circuits.

Do not take capacitance measurements until the capacitor to be measured has been fully discharged.
