3. Reverse the probe tip and common clip connections and
note that the numerical reading remains approximately the
same but the opposite polarity sign is displayed. Disconnect
the de source.
4. Depress the RMS pushbutton, set the INPUT COUPLING
switch to AC, select a VOL TS-mA/D IV range (blue scale)
compatible with the amplitude of the ac voltage source to be
measured, and connect the ac voltage source between the
probe tip and probe common clip. The display represents
the value of the ac voltage source. Set the RMS pushbutton
to the out position and note that the average de value of the
ac signal is zero verifying that the ac filter is operational. Dis
connect the ac signal.
Current Measurement Display
5. Depress the mA pushbutton, set the RMS pushbutton to
the out position, and select a VOL TS-mA/D IV range (blue
scale) compatible with the amplitude of the current genera
ted by the de voltage source and a series current limiting
resistor. Connect the de voltage source in series with the
current limiting resistor, and connect this combination be
tween the mA-.Q jack and the COMMON jack with test
leads. The display represents the value of the de current.
Disconnect the de source and resistor.
6. Depress the RMS pushbutton and select a VOL TS-mA/
DIV range (blue scale) compatible with the amplitude of the
current generated by the ac voltage source and a series cur
rent limiting resistor. Connect the ac voltage source in series
with the current limiting resistor, and connect this combina
tion between the mA-.Q jack and the COMMON jack with
test leads. The display represents the value of the ac current.
Disconnect the ac source and resistor.
Resistance Measurement Display
7. Depress then pushbutton and set the RMS pushbutton
to the out position. Select a VOL TS-mA/DIV range compa
tible with the value of the resistor to be measured and con
nect the resistor between the mA-r2 jack and COMMON jack
with test leads. The display represents the value of the re
sistor.
Overrange Display
8. Disconnect the resistor and the display shows an overrange
condition.
