AUTO / MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into Autoranging.
This automatically selects the best range for the measurements being
made and is generally the best mode for most measurements. For
measurement situations requiring that a range be manually selected,
perform the following:
1. Press the
RANGE
key. The “
AUTO”
display indicator will turn off.
2. Press the
RANGE
key to step through the available ranges until you
select the range you want.
3. To exit the Manual Ranging mode and return to Autoranging, press
and hold the
RANGE
key for 2 seconds.
Note:
Manual ranging does not apply for the Capacitance and
Frequency functions.
MAX/MIN
Note:
When using the MAX/MIN function in Autoranging mode, the
meter will “lock” into the range that is displayed on the LCD when
MAX/MIN is activated. If a MAX/Min reading exceeds that range,
an “OL” will be displayed. Select the desired range BEFORE
entering MAX/MIN mode.
1. Press the
MAX/MIN
key to activate the MAX/MIN recording mode. The
display icon "
MAX
" will appear. The meter will display and hold the
maximum reading and will update only when a new “max” occurs.
2. Press the
MAX/MIN
key again and the display icon "
MIN
" will appear.
The meter will display and hold the minimum reading and will update
only when a new “min” occurs.
3. To exit MAX/MIN mode press and hold the
MAX/MIN
key for 2
seconds.
