To turn on the instrument turn the range knob from the OFF position to
any measurement range.
Note: For best battery life ALWAYS turn the function switch to the OFF
position when the meter is not in use. These meters have an Auto OFF
that automatically shuts the meter OFF if left switched on. AVO300:15
minutes, AVO310: 30 minutes.
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.
