First, just before you make any measurement you must know what you
are checking. If you are measuring voltage then select the AC (10V, 50V,
250V, or 1000V) or DC (0.5V, 2.5V, 10V, 50V, 250V, or 1000V) range.
If you are measuring the resistance, select the Ohms range (Rx1Ω,
Rx10Ω, Rx100 Ω, Rx1kΩ or Rx10kΩ). If you are measuring the current
then select the appropriate current range (DCmA) as shown in the photo
in the previous page.

Now that you know the very basic of a multimeter, I’ll describe how you
can use the meters (analogue and digital) to take voltage, resistance, and
current readings in the next few chapters.
