Activate continuity testing (acoustic signal ON):
Note!
☞
The two measurement cables may not come into
contact with one another when the multimeter is
switched on, or prior to measurement function
selection, as this would lead to zero point adjust-
ment.
OL is displayed if the DUT is not connected.
➭ Briefly press the ESC|FUNC multifunction key.
Activation is acknowledged with an acoustic signal.
The symbol is simultaneously displayed at the LCD.
➭ Connect the measurement cables to the DUT.
Deactivate continuity testing (acoustic signal OFF):
➭ Briefly press the ESC|FUNC multifunction key a second
time.
Deactivation is acknowledged with an acoustic signal.
The symbol disappears from the LCD.
12 Diode Testing
➭ Be certain that the device under test is voltage-free.
Extraneous voltages distort the measurement results!
➭ Set the rotary switch to“ ”.
➭ Connect the DUT as shown.
Conducting Direction and Short-Circuit
The measuring instrument displays the forward voltage in
volts (display: 4¾ places). As long as the voltage drop
does not exceed the maximum display value of 1.8 V, you
can test several elements connected in series, or reference
diodes with small reference voltages.
Reverse Direction or Interruption
The measuring instrument indicates overflow “OL”.
Note!
☞
Resistors and semiconductor paths connected in
parallel to the diode distort measurement results!
