5-5. AC Current (Frequency, Duty Cycle) Measurements

CAUTION : Do not make 10A current measurements for longer than 30 seconds.
Exceeding 30 seconds may cause damage to the meter and/or the test leads.
1. Insert the black test lead banana plug into the
negative COM jack.
2. For current measurements up to 6000µA AC, set the
function switch to the
the red test lead banana plug into the µA/mA jack.
3. For current measurements up to 600mA AC, set
the function switch to the
insert the red test lead banana plug into the µA/mA
jack.
4. For current measurements up to 10A AC, set the
function switch to the
insert the red test lead banana plug into the 10A
jack.
5. Press the MODE button to indicate "AC" on the
display.
6. 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 neutral side of
the circuit.
8. Touch the red test probe tip to the "hot" side of the
circuit.
9. Apply power to the circuit.
10. Read the current in the display.
11. Press the Hz/% button to indicate "Hz".
12. Read the frequency in the display.
13. Press the Hz/% button again to indicate "%".
14. Read the % duty cycle in the display.
Press the Hz/% button to return to current measurement.
