Making Measurements

only when both the ac and dc signals drop below 10% of the

present range. For AC+DC, ranging is controlled by the

underlying values of the ac and dc signals and not by the sum of

the AC+DC calculation.

To exit the AC+DC mode, press the softkey labeled Menu and

select the default mode for the selected function. For dc volts

and dc millivolts functions, move the menu selector to VDC and

press the softkey labeled VDC. For the current functions, move

the menu selector to the AC,DC menu item and press either the

AC or DC softkey.
