25 Triplett Model 9045
7.2.6.1 Connect the black test lead to the COM jack, and the red test lead to the
jack.
7.2.6.2 Set the FUNCTION switch to the position. Press the SELECT
button, repeatedly if necessary, to select the Continuity Beeper mode. The
annunciator will turn on when the Continuity Beeper mode is selected.
The LCD display will indicate overrange (i.e. “OL”).
7.2.6.3 Connect the test leads to the device or circuit being tested. If the continu-
ity of the tested circuit is less than about 120 Ohms, the beeper will sound
and the approximate resistance will be displayed on the LCD.
7.2.7 Diode Test
WARNING!!!
Do not apply voltage or current to the meter when the
FUNCTION switch is set to
7.2.7.1 Connect the black test lead to the COM jack, and the red test lead to the
jack.
7.2.7.2 Set the FUNCTION switch to the position. Press the SELECT button,
repeatedly if necessary, to select the Diode Test mode. The
annuncia-
tor will turn on when the Diode Test mode is selected.
The LCD display will indicate overrange (i.e. “OL”).
7.2.7.3 Connect the test leads to the device or circuit being tested, observing the
appropriate polarity. To test a simple diode, connect the red test probe to
the Anode of the diode and the black test lead to the Cathode (“banded”
end) of the diode. The LCD will indicate the voltage drop of the diode.
Reverse the connections of the test probes to the diode. The LCD should
indicate overrange (“OL”). If the display reads “0.000 v” when the leads are
connected in either direction to a standard silicon diode, the diode is
probably shorted.
Note: The reading displayed on the LCD is an accurate indication of the voltage
drop of the device or circuit being measured.
