4-5.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
µA AC/DC
position
and insert 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
mA AC/DC
position
and 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
10A AC/DC
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 the
Hz/%
button to indicate “
Hz
”.
11. Read the frequency in the display.
12. Press the
Hz/%
button again to indicate
“
%
”.
13. Read the % duty cycle in the display.
14. Press the
Hz/%
button to return to
current measurement.
