Connect the black test probe tip and the red test probe tip in series to

the circuit whose current you want to measure.

8. Apply power to the circuit, read the current on the display.

9. Press the Hz/% Button to indicate "Hz", read the frequency on the

display.

10. Press the Hz/% Button again to indicate "%", read the % duty cycle

on the display.

11. Press the Hz/% Button to return to current measurement.

6.5. RESISTANCE MEASUREMENTS

WARNING: To avoid electric shock, disconnect power to the unit

under test and discharge all capacitors before taking any resistance

measurements. Remove the batteries and unplug the line cords.

1. Set the function switch to the Ω CAP

2. Insert the black test lead banana plug into the

negative COM jack. Insert the red test lead banana

plug into the positive Ω jack.

3. Press the MODE button to indicate "Ω" on the

display.

4. Touch the test probe tips across the circuit or part

under test. It is best to disconnect one side of the

part under test so the rest of the circuit will not

interfere with the resistance reading.

5. Read the resistance on the display.

WARNING: To avoid electric shock, never measure continuity on

circuits or wires that have voltage on them.

1. Set the function switch to the Ω CAP

2. Insert the black lead banana plug into the negative

COM jack. Insert the red test lead banana plug into

the positive Ω jack.

3. Press the MODE button to indicate "

on the display

4. Touch the test probe tips to the circuit or wire you

wish to check.

5. If the resistance is less than approximately 30Ω,

the audible signal will sound. If the circuit is open,

the display will indicate "OL".
