DC Voltage Measurements

Warning:
Observe all safety precautions when working on live
voltages.
1. For DC measurements, touch the red test probe to the positive side of
the circuit and the black test probe to the negative side of the circuit.
2. When measuring DC voltage, only one voltage indicator will be
illuminated. If the red test probe is touching the positive side of the
circuit and the black test probe is touching the negative side of the
circuit, then the "+ "or positive DC voltage indicator will be illuminated.
If the red test probe is touching the negative side of the circuit and the
black test probe is touching the positive side of the circuit, then the "–
"or negative DC voltage indicator will be illuminated.
3. The top of the tester is marked AC on the left and DC on the right.
When measuring DC voltage, use the DC voltage scale on the right side
increments.
4. The approximate DC voltage is the number on the DC voltage scale
that corresponds to the top-most LED that is illuminated.
5. In the figure below, the "+" or positive voltage indicator is illuminated
whereas the "- "or negative voltage indicator is not illuminated. This
signifies that the voltage tester is measuring DC voltage. In addition,
