Ac Current Measurements - Craftsman 82003 Owner's Manual

AC CURRENT (Frequency, Duty Cycle) MEASUREMENTS
CAUTION: Do not make current measurements on the 20A
scale 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 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 mA
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 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.
