Suppose your condition is in AC 100V and you want to convert the voltage to the 220V.
【Step 1】Verify that the meter is disconnected as shown as the Figure 2-1.
【Step 2】Open the voltage setting selector cap as shown as the Figure 2-2. (You might need a pair of tweezers to do so)
【Step 3】Remove the red voltage setting selector from the right middle seam as shown as the
Figure 2-3. (You might need a pair of tweezers to do so)
【Step 4】Turn it over to 220V position as shown as the Figure 2-4.
【Step 5】Insert the voltage setting selector back into the socket and close the cap as shown as the Figure 2-5.
