AC Current (Frequency, Duty Cycle) Measurement
CAUTION: Do not make 20A 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 4000μA AC, set the function switch
to the yellow μA position and insert the red test lead banana plug
into the μA/mA jack
3.
For current measurements up to 400mA AC, set the function switch
to the yellow mA position and insert the red test lead banana plug
into the μA/mA jack
4.
For current measurements up to 20A AC, set the function switch to
the yellow 10A/HZ/% position and 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
Touch the red test probe tip to the "hot" side of the circuit
8.
Apply power to the circuit
9.
Read the current in the display
10. Press and hold the MODE button to indicate "Hz"
11. Read the frequency in the display
12. Momentarily press the MODE button again to indicate "%"
13. Read the % duty cycle in the display
14. Press and hold the MODE button to return to current measurement
