Figure 2-1. Measuring DC Volts
WARNING
To avoid possible electric shock, multimeter damage and/or
equipment damage, do not attempt to do any voltage measurements if
the voltage is above 1000V DC / 750V AC RMS. 1000V DC / 750V AC
RMS are the maximum voltages that this multimeter is designed to
measure.

input terminals
respectively.
2. Select the desired DC voltage range, or set to auto range.
3. When the magnitude of the voltage to be measured is unknown, always start
with the highest range.
4. Connect the test leads in parallel with the circuit to be measured. Be careful
not to touch any live conductors with your hands. Note the reading.
5. For DC voltage readings, the red lead should be connected to the positive side
of the circuit, the black lead to the negative side. A minus sign on the left-hand
side of the LCD will appear if the leads are connected the other way around.
6. When all measurements have been completed, disconnect the test leads from
the circuit under test. Remove the test leads from the multimeter.
