measurements being made and is generally the best mode for most
measurements. For measurement situations requiring that the range
be manually held, perform the following:
1. Press the "RANGE" button. The "AUTO" indicator will extinguish
and the currently selected range will be held.
2. Press the "RANGE" button to step through the available ranges
until you select the range you want.
3. Press and hold the "RANGE" button for 2 seconds to exit the
manual ranging mode and return to "AUTO" mode.

RANGE: Pressing the RANGE button selects the manual measuring
range in the current measuring function. If the RANGE
button is held down for 2 seconds, the device returns to

long press switches to the Peak-MAX or Peak-MIN
measurement function, which captures the highest or
lowest peak of an AC waveform (P 3445 only).
