Making Multimeter Measurements
Measuring AC or DC Current
To measure a AC or DC current which is
less than 400 mA
, do the following:
(1)
Push
DMM
button on the front panel. Select
Current
in the bottom menu, select it
again to switch between
ACA
(AC current ) or
DCA
(DC current).
(2)
Select
Configure
in the bottom menu, select
Current
as
mA
in the right menu.
(3)
Connect the black test lead to the
COM
terminal
on the back of the oscilloscope.
Connect the red test lead to the
mA
terminal.
(4)
Turn off the power of the measured circuit. Discharge all high- voltage capacitors.
(5)
Disconnect the circuit path to be tested. Connect the black test lead to one side of the
circuit (with a lower voltage); connect the red test lead to the other side (with a higher
voltage). Reversing the leads will produce a negative reading, but will not damage the
multimeter.
(6)
Turn on the power of the measured circuit, and read the display.
(7)
Turn off the power of the measured circuit and discharge all high-voltage capacitors.
Remove the test leads and restore the circuit to the original condition.
To measure a AC or DC current which is
400 mA to 10 A
, do the following:
(1)
Push
DMM
button on the front panel. Select
Current
in the bottom menu, select it
again to switch between
ACA
(AC current ) or
DCA
(DC current).
(2)
Select
Configure
in the bottom menu, select
Current
as
10A
in the right menu.
(3)
Connect the black test lead to the
COM
terminal
on the back of the oscilloscope.
Connect the red test lead to the
10A
terminal.
(4)
Turn off the power of the measured circuit. Discharge all high- voltage capacitors.
(5)

Measuring AC or DC Voltage
(1)
Push
DMM
button on the front panel. Select
Current
in the bottom menu, select it
again to switch between
ACA
(AC current ) or
DCA
(DC current).
(2)
Connect the black test lead to the
COM
terminal on the back of the oscilloscope and
the red test lead to the
V/Ω/C
terminal.
