• An ohmmeter measures resistance by the amount of current flowing through the resistor being measured.

• The maximum value of a meter scale is called the full scale value.

• The number of divisions on the meter scale depends on the range the meter is designed to measure.

• Ammeters and voltmeters are read from left to right and have a linear scale.

• Ohmmeters are read from right to left and have nonlinear scales.

• An analog ohmmeter must be calibrated before use to compensate for battery deterioration.
