3.3 Method to increase the effective radius of detecting charged 

      circuits

When the transmitter is directly connected to the phase line and neutral line, the signals 
are conducted on two parallel circuits (as shown in Fig.3-3-1), so the twisting of circuits 
may sometimes cause signals to counteract each other, leading to an effective radius of 
0.5m at most . In order to eliminate this effect ,  the connection must be as shown in 
Fig.3-3-2, where the loop line uses a separate cable to increase the effective radius to 
over 2.5m, and loop lines with longer distances can be provided by the cable reel 
(see Fig.3-3-2).

When connecting charged circuits 
to the transmitter, please do abide 
by the safety instructions.

Pay attention to the distance 
between the transmitter and the 
circuit to be detected, in order to 
clearly determine the circuit 
through signals.

1. In the process of detecting the circuit, the stronger the signal displayed on the 
    digital tube of the detector, the closer the cable detected by the detector.
2. Adjust the transmitting power of the transmitter to adapt to different radiuses of 
    detection. 
3. Select the manual mode on the receiverand select suitable receiving sensitivity 
    to precisely locate the circuit. 

3.4 Identify voltage in the grid and search for breakages in the 

      circuit

Preconditions:

The circuit must be charged with AC voltage;

※

 The measurement must be conducted according to Fig.3-4;

※

 Set the transmitter to "Grid Voltage Identification" mode (namely the UAC mode). 

※

1.The AC signals detected by the transmitter in UAC mode only show that whether 
   the circuit is charged, and the precise measurement of voltage should be done 
   through the voltmeter function of the transmitter.
2.When searching for the ends of multiple power lines, it is necessary to connect 
   each line to the phase line separately. 

1.This application does not need the transmitter. (Unless you want to use the 
   voltmeter function of the transmitter to precisely measure the voltage in the 
   circuit)
2.The signal strength columns displayed on the transmitter and the signal tone 
   frequency are related to the voltage in the circuit to be detected and the distance 
   to the circuit. The higher the voltage and the shorter the distance to the circuit, the 
   more the columns displayed and the higher the signal tone frequency.
