OPERATION

For best battery life 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 30 minutes
elapse between uses.
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
