3.5 IDENTIFICATION OF THE MAINS VOLTAGE AND SEARCH FOR
BREAKS IN THE CIRCUIT
This application does not need the transmitter (unless you want to use its
voltmeter function to measure the voltage in the circuit precisely.).
Preconditions:
The circuit must be connected to mains and live.
The measurement must be made as shown in Fig. 25;
Set the receiver to the "Identification of mains voltage" mode (designated
"UAC mode").
Fig.25
Remarks:
The AC signals detected by the receiver in UAC mode indicate only whether
the circuit is live; for a precise measurement of the voltage, use the voltmeter
function of the transmitter.
During the search for the ends of several supply lines, the lines must be
connected separately, one by one.
The number of bars indicating the strength of the received signal and the
frequency of the audible signal emitted depend on the voltage in the circuit to
be detected and on the distance from this circuit. The higher the voltage and
the shorter the distance from the circuit, the more bars are displayed and the
higher the frequency of the audible signal.
