DC current measurement / A=
Set the appropriate range using the selector switch. Connect the black test lead to the
"COM" jack and the red test lead to the "mA" or "10 A" jack. Connect the test leads with
the test object and read off the measurement result from the display. The current direc-
tion is indicated by the sign.
You must use the "10 A" jack when measuring currents above 600 mA!
