AUTO-MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into the
Auto Range mode. 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:
Press the RANGE key. The AUTO display indicator will
Press RANGE to step through the available ranges until
the desired range is selected.
To exit the Manual Ranging mode and return to Auto
Range, press and hold the RANGE key for 2 seconds.
When in the autoranging mode the meter will up-range
to the next higher range when the measured value is
above 90% of full scale. This guard band prevents
autorange oscillation. If maximum counts are required
in this band, use manual ranging.
Note: Manual range does not apply to Capacitance,
Frequency or Temperature modes.
The relative measurement feature allows you to make
measurements relative to a stored reference value. A reference
voltage, current, etc. can be stored so that subsequent
measurements can be made in comparison to that value. The
displayed value is the difference between the reference value
and the measured value.
Perform the measurement as described in the operating
Press the REL button to store the reading (the REL
indicator will appear on the display).
The display will now indicate the difference between
stored value and subsequent measurements.
Press the REL button to exit the relative mode.
Note: The Relative mode is not available when measuring
Frequency or Duty Cycle.
