Non-Contact Voltage Detection
Figure 6.7
Non-Contact Voltage Detection
1. The circuit under test must be live and connected to the mains.
2. Set the Receiver to the
U
AC
mode.
3. Hold the tip of the Receiver close to the source of AC voltage to test.
4. The mains AC voltage detected by the Receiver in the
U
AC
mode only indi-
cates whether or not the circuit is live.
5. While searching for the ends of the supply lines, the lines must be con-
nected separately, one by one.
6. The number of bars on the bar graph and the frequency of the audible
tone increases as the strength of the detected signal increases. The clos-
er the sensor is to the source of voltage, the stronger the signal detection.
