5.4 Resistance Measurements
Warning
: Do not perform diode, resistance or continuity tests before removing power
from capacitors and other devices under test during a measurement. Injury to persons
can occur.
1.
Refer to Fig. 5-2. Set the function switch to the
position.
2.
Use
to step to the
Ω
display if necessary.
3.
Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive
Ω
terminal.
4.
Touch the tips of the probe across the circuit or component under test.
5.
Read the resistance value on the display.
5.5 Continuity Test
Warning
: Do not perform diode, resistance or continuity tests before removing the
power from capacitors and other devices under test during a measurement. Injury to
persons can occur.
1.
Refer to Fig. 5-2. Set the function switch to the
position.
2.
Use the
button to select continuity. The
indicator will appear.
3.
Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive terminal.
4.
Touch the tips of the probe across the circuit or component under test.
5.
If the resistance is <
20Ω the meter beeps. I
f the resistance is >
200Ω the meter
will not beep. If the resistance is
> 20Ω but
<
200Ω
the beeping will stop at an
unspecified point.
