3. Frequency
measurement
1. Set the switch to
.
2. Connect the black lead to the “COM” terminal and the red lead to “
+
”.
3. Place the test probes on the terminals of the circuit to be measured.
*
Connect the instrument as for a voltage measurement
4.
Read the measurement value indicated on the display unit.
5. Press
to obtain the period of the signal 1/F (ms).
4. Resistance
measurement
1. Set the switch to
.
2. Connect the black lead to the “COM” terminal and the red lead to “
+
”.
3. Place the test probes on the terminals of the component.
Remark: Resistance measurements must be made with power off.
However, while the presence of a voltage will prevent or throw
off the measurement, it will not damage the instrument.
4. Read the measurement value indicated on the display unit.
5. “
O.L
” is displayed, if the circuit is open.
5. Audible
continuity
measurement
1. Set the switch to
