3. Press SELECT to toggle between AC/DC;
4. Break the circuit path to be measured. Then connect the test leads across the break and apply power;
5. Read the measured current on the display.

Caution:

• Do not measure current that exceeds the MAX Value as indicated in the Specifications;
• Use the 20A Terminal and the Current-A Mode when you are measuring an unknown current. Then switch to the mA/μA Terminal and the smaller Current Mode if necessary.

Measure Resistance
