6. OPERATION
WARNING: 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.
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.
6.1. AUTO RANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into Auto ranging.
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 or
select diode /beeper, AC/DC Clamp
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 Auto ranging, press
and hold the RANGE key for 2 seconds.
NOTE: Manual ranging does not apply for the Frequency functions.
