LCD indicates which mode is selected.
Apply test leads to the circuit to be tested to measure voltage.
The meter will auto-range to display the measurement in the most
appropriate range.
NOTE: If "–" appears on the LCD, this indicates negative polarity for
DC voltage.
NOTE: When in a voltage setting and the test leads are open,
readings of order mV may appear on the display. This is noise and
is normal. By touching the test leads together to close the circuit
the meter will measure zero volts.
NOTE: When voltages in excess of 25V AC or 60V DC are measured
the hazardous voltage indicator
will be present on the display.
