How are the various quantities measured? (continued)
6. Diode test
1. Set the switch to
.
2. Press
twice; the “
” symbol is displayed.
3. Connect the black lead to the “COM” terminal and the red lead to “
+
”.
4. Place the test probes on the terminals of the component:
5. Read the measured threshold voltage of the junction indicated
on the display unit.
6. “
O.L
” is displayed, if the circuit is open or the threshold of the diode >3V.
7. Capacitance
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:
4. Read the measurement value indicated on the display unit.
“
O.L
” is displayed, if the value to be measured exceeds the capacitance of
the range.
“
O.L
” is displayed, if the capacitor is short-circuited.

For high values, the measurement cycle includes the display of "run" with
a "chaser" decimal point. This means that acquisition is in progress; wait
for the display of the digital result.
"Run" is displayed immediately, if the previous measurement
was in a small range.

The prior discharge of very high capacitances helps shorten the
measurement time.
