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. True-rms Digital Multimeters Making Measurements 27
