Autoraging/Manual Ranging Selection; Data Hold - Craftsman 82139 Owner's Manual

I ARNING: Risk of electrocution. High-voltage circuits, both AC and DC,
are very dangerous and should be measured with great care.
1. ALWAYS turn the function switch to the OFF position when the meter is
not in use. This meter has Auto OFF that automatically shuts the meter
OFF if 15 minutes elapse between uses.
2. If "OL" appears in the display during a measurement, the value exceeds
the range you have selected. Change to a higher range.
NOTE: On some low AC and DC voltage ranges, with the test leads not
connected to a device, the display may show a random, changing
reading. This is normal and is caused by the high-input sensitivity.
The reading will stabilize and give a proper measurement when
connected to a circuit.
AUTORANGING / MANUALRANGING 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 button. The "AUTO" display indicator will turn off.
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
ManualRanging mode and return to AutoRanging.
DATA HOLD
The Data Hold function allows the meter to "freeze" a measurement for
later reference.
1. Press the DATA HOLD button to "freeze" the reading on the indicator.
The indicator "HOLD" will appear in the display.
2. Press the DATA HOLD button to return to normal operation.
NOTE: The DATA HOLD function works in the FREQUENCY mode only
when a signal is present.
