Current measurements
Set up your multimeter as shown in the figure below to per-
form current measurements. Press   to switch between 
AC, DC, AC+DC, or % scale current measurements. When mea-
suring DC current from a mixed signal in DC measurement 
mode, ensure that the Filter (
) is enabled.
Always use the proper function, range, and terminals for 
current measurements. Set the positive input terminal to 
the   terminal for currents below 440 mA, and the 
 terminal for currents above 440 mA.
