have selected, change to a higher range. On some low DC and AC 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 the circuit.

  7.  Always turn the function switch to the OFF position when the meter is not in use. The 

meter will automatically shut OFF if not used for 15 minutes.

Rotary Function Switch

The Rotary Function switch permits the user to select a measurement function by position-
