Measuring Ac Or Dc Current - Fluke 17B User Manual

the dc range that either matches or is higher than the
previously noted ac range. Using this procedure minimizes
the effects of ac transients while making accurate dc
measurements.
1. Choose ac or dc by turning the rotary switch to v, V,
or M.
2. Connect the red test lead to the J terminal and the
black test lead to the COM terminal.
3. Measure the voltage by touching the probes to the
desired test points of the circuit.
4. Read the measured voltage on the display.

Measuring AC or DC Current

1. Turn the rotary switch to
2. Toggle between ac or dc current measurement by
pressing the YELLOW button.
3. Connect the red test lead to either the A, or mA i
terminal based on the current to be measured and
connect the black test lead to the COM terminal.
4. Break the circuit path to be measured. Then connect
the test leads across the break and apply power.
5. Read the measured current on the display.
