2. Put the range switch to the corresponding ACV range and then put the test probes to the
source to be measured.
Figure 3. The measured voltage in this figure is 240 V AC.
Note:
1. If the range of the voltage to be measured is unknown, put the range switch to the highest
rank, then according to the value displayed, turn to the corresponding range
2. If on the display is shown "1", this means that the range is exceeded and the range switch
must be set to a higher gear
3. Do not measure a voltage over 600 Vrms, because there is a risk to damage the
instrument circuit
4. When measuring a high voltage circuit, pay attention not to touch any high voltage part of
the circuit.
