DC CURRENT MEASUREMENT
7. Insert the black test lead banana plug into the negative (COM) jack.
8. For current measurements up to 4000uA DC, set the function switch to the uA position and
insert the red test lead banana plug into the (uA) jack.
9. For current measurements up to 400mA DC, set the function switch to the mA range and
insert the red test lead banana plug into the (mA) jack.
10. For current measurements up to 10A DC, set the function switch to the A position and
insert the red test lead banana plug into the 10A jack.
11. Press
the AC/DC button until “
DC
”
appears in the display.
12. Remove power from the circuit under test, then open up the circuit at the point where you
wish to measure current.
7. Touch the black test probe tip to the negative side of the circuit. Touch the red test probe
tip to the positive side of the circuit.
8. Apply power to the circuit.
9. Read the current in the display. The display will indicate the proper decimal point,
value and symbol.
AC CURRENT MEASUREMENT

11. For current measurements up to 10A, set the function switch to the A position and insert
the red test lead plug into the (10A) jack.
12. For current measurements up to 400mA, set the function switch to the mA range and
insert the red test lead banana plug into the (mA) jack.
13. For current measurements up to 10A AC, set the function switch to the A position and
insert the red test lead banana plug into the 10A jack.
14. Press the MODE button. The measurement mode will change between AC or DC as
required.
15. Remove power from the circuit under test, then open up the circuit at the point where you
wish to measure current.
16. Touch the black test probe tip to the negative side of the circuit. And touch the red test
probe tip to the positive side of the circuit.
