4.
Connect the test leads in series with the load under measurement.
5.
Apply power to the circuit.
6.
Read the current in display.
5.8. Resistance Measurement
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
Pres the MODE-button to indicate on the display.
2.
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.
Note:
1.
If the resistance value being measured exceeds the maximum
voltage of the range selected, an over-range indication will
be displayed ("OL"). Select a higher range. For resistance approx.
MΩ and above, the meter may take a few seconds to stabilize. This
is normal for high resistance readings.
2.
When the input is not connected, i. e. at open circuit, the figure "OL"
will be displayed for the overrange condition.
3.
When checking in-circuit resistance, be sure the circuit under test
has all power removed and that all capacitors are fully discharged.
5.9. Continuity Check
WARNING! To avoid electric shock, never measure continuity on
circuits or wires that have voltage on them.
1.
Set the function switch to the
2.
Press the MODE-button to indicate
3.
Touch the test probe tips to the circuit or wire you wish to check.
If the resistance is less than approx 150 , the audible signal will sound.
4.
If the circuit is open, the display will indicate "OL".
