Autorange and
Manual Ranging

Hold

Note
In addition to the functions selected by the FUNCTION keys, the multimeter
can perform direct-sampled or sub-sampled digitizing, ratio measurements,
and AC or AC+DC voltage measurements using the synchronous or random
measurement methods. These functions can be selected from the front panel
by accessing the appropriate command(s) using the alphabetic menu keys
(these keys are discussed later in this section under "Using the MENU
Keys"). For more information on any measurement function or method, refer
to Chapter 1.
In the power-on state, the multimeter automatically selects the appropriate
measurement range. This is called autorange. In many cases, you will
probably want to continue using autorange. However, you have two other
ranging choices: hold and manual ranging.
This choice allows you to shut off autoranging. To do this, let autorange
choose a range and then press:
Hold
When you press the blue shift key, the display's SHIFT annunicator
illuminates. The shifted keyboard functions are printed in blue above the
keys.
