MAKINGMULTIMETERMEASUREMENTS
Press the DMM/OSC key; the oscilloscope will switch to the multimeter mode. The
meter will prompt the user to correctly insert the test leads. Use the A, V, and R keys
to select the desired multimeter function.
MEASURING RESISTANCE
To measure resistance, first remove power from the component or circuit under test
and then follow these steps:
1. Insert the black lead into the COM banana jack input and the red lead into
the V/Ω/C banana jack input
2. Press the R key. An ‘R’ appears at the top of the screen
3. Connect the red and black test leads to the resistor or circuit under test. The
resistance value will appear on the screen (unit of measure: Ohms)
Refer to the example diagram below in Figure 2.
Figure 2: Resistance Measurement
MEASURING DIODE VOLTAGE
To make a measurement on the diode, do the following:
1. Insert the black lead into the COM banana jack input and the red lead into
the V/Ω/C banana jack input
2. Press the R key. An ‘R’ appears at the top of the screen
3. Press the SET key repeatedly until the diode symbol is displayed
4. Connect the red and black leads to the diode and read the displayed voltage
(V)
