Using Auto Volts Selection (114 & 117 only)
With the function switch in the x position, the Meter
automatically selects a dc or ac voltage measurement
based on the input applied between the V or + and COM
jacks.
This function also sets the Meter’s input impedance to
approximately 3 kΩ to reduce the possibility of false
readings due to ghost voltages.
