5.4.7 Making a DC current Measurement (AAC)

In order to carry out the measurement of current it is necessary to connect in
series the meter and the circuit under test. Make sure that the circuit is disconnected
before doing this connection.
To measure a DC current which is less than 400 mA , do the following:
1. Press the A key and DCA appears at the top of the screen. The unit on the
main reading screen is mA. mA and 20A will display on the right bottom of
screen, press F4 or F5 to switch the measurement between Ma and 20A.
400mA is acquiescently.
2. Insert the black lead into the COM banana jack input and the red lead into the
mA banana jack input.
3. Connect the red and black leads to the measured points and the DC current
values of measured points will be displayed on the screen. Look at the
display; you can see a screen that looks like the following figure 40.
