2.3 Diode test ( ) measurements
1.
Press the function key to select function.
2.
Connect the test lead to the and COM input terminals
of the instrument.
3. Connect the test lead to the semiconductor junction (diode or
transistor) as shown in Fig.2-1,and read the displayed value.

2.3.1 dBm measurements
This function converts a voltage measurement into dBm. The
function can be selected only when a voltage function (volts ac,
volts dc, or volts ac+dc) is selected. Press [SHIFT] key, then press
[dBm] key, the secondary display shows the dBm value that
reposed on the voltage value showed in the primary display.
For example, if press [SHIFT] key, then [dBm] is pressed when
measuring voltage in the max mode, the maximum value is con-
verted to dBm. To release the dBm function, Press [SHIFT] key,
then press [dBm] again. The dBm mode and AC+Hz mode are not
selected concurrently.
The standard reference impedance of the instrument is 600 Ω .
