Resistance Measurements - PeakTech 3355 Manual De Instrucciones

4. For current measurements up to 10 A DC, set the function
switch to the 10 A position and insert the red test lead banana
plug into the 10 A jack.
5. Press the "MODE" button until "AC" appears in the display.
6. Remove power from the circuit under test and open the circuit
at the point where you wish to measure current.
7. Touch the black test probe tip to the negative side of the circuit
and touch the red test probe tip to the positive side of the
circuit.
8. Apply power to the circuit.
9. Read the current in the display. The display will indicate the
proper decimal point, value and symbol.

5.7. Resistance measurements

Warning:
To avoid electric shock, disconnect power to the unit under test and
discharge all
measurements. Remove the batteries and unplug the line cords.
1. Set the function switch to the "OHM" position.
2. Insert the black test lead banana jack into the negative
jack and the red test lead banana plug into the positive Ω jack.
3. 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.
4. Read the resistance in the display. The display will indicate the
proper decimal point, value and symbol.
