Autoranging/manual range selection

When the meter is first turned on, it automatically goes into au-
toranging. This automatically selects the best range for the meas-
urements 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 turn
off,

Press the RANGE key to step through the available ranges
until you select the range you want,

Press and hold the RANGE button for 2 seconds to exit the
ManualRanging mode and return to AutoRanging.
7.2

Relative mode

The relative measurement feature allows you to make meas-
urements relative to a stored reference value. A reference voltage,
current, etc. can be stored and measurements made in comparison
to that value. The displayed value is the difference between the ref-
erence value and the measured value.
In order to realise relative measurement it is necessary to real-
ise the following actions:

Perform the measurement as described in the operating
instructions,

Press the REL button to store the reading in the display and
the "REL" indicator will appear on the display,

The display will now indicate the difference between the stored
value and the measured value,

Press the REL button to return to normal operation.
