7. Read the display. If
0o
appears on the highest range,
the resistance is too large to be measured or the circuit
is an open circuit.
8. (15XP-B) The 2000 M range has a fixed 10-count
offset in the reading. For example, when measuring
1100 M, the display reads 1110. The 10 residual must
be subtracted to obtain the actual value of 1100 M
Testing for Continuity
(See Figure 6)
1. Set the Function Switch to
.
2. Connect the test leads: Red to V , Black to COM.
3. Turn off power to the circuit being measured.
4. Discharge any capacitors that may influence the
reading.
5. Connect the test probes across the resistance or the
two points of test.
6. Listen for the tone that indicates continuity.
Testing Diodes
(See Figure 7)
1. Set the Function Switch to
.
2. Connect the test leads: Red to V , Black to COM.
3. Turn off power to the circuit being measured.
4. Free at least one end of the diode from the circuit.
5. Connect the test probes across the diode.
6. Read the display. A good diode has a forward voltage
drop of about 0.6 V. An open or reverse biased diode
will read
0o
.
Measuring Capacitance
(35XP-A only) (See Figure 8)
1. Set the Function Switch to the
function.
2. Connect the test leads: Red to
, Black to COM.
