. A beeper alert is
generated at <5% of a selected range in Manual Range
mode. The beeper alert is turned on with ALERT ))).
Diode test mode. A diode connected to the red
and black 4-mm banana jack inputs is tested. The
measurement current through the diode is 0.5 mA. The red
banana jack is the high input, and the black banana jack
(COM) is the low.
The result is displayed as the forward or reverse voltage of
the diode. A beeper alert is generated at forward voltage.
The beeper alert is turned on with ALERT ))).
The time base is fixed at 5 ms/DIV and the attenuator at 3V.
NOTE
In the diode and resistance modes, the black COMmon
banana jack is not connected internally to the common of
BNC INPUTS A and B.
