LCD indicates which mode is selected.
2. 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, the test leads are being applied
to the circuit in reverse polarity. Swap the position of the leads to
correct this.
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: The Hazardous Voltage indicator appears for voltages >30V.
