3.4.5 Power mode - Pr
LKZ-720 may operate in "Pr" mode, which is called "Power" mode. It involves the transmitter set
in "Pr" mode and connected to the closed circuit without voltage.
Fig. 11 Diagram of the power mode.
In in the circuit, the transmitter forces the current flow limited by circuit impedance. The received
signal is proportional to the current flow, which translates into a significant increase in the object de-
tection range.
This mode is particularly suitable for tracing the cable routes.
Note
Due to the high power consumption in Power mode, take into account
rapid discharge of batteries/rechargeable batteries that supply the transmit-
ter.
Note
When the impedance is too low, transmission may not possible in this
mode. Then, use the voltage-current mode (UI.
3.4.6 The mode of detecting safety devices - FUSE
This set allows the location of system safety devices. It involves the transmitter, which is connect-
ed to a live circuit - between the phase conductor L and a neutral conductor N - and which generates
current waveforms in the tested circuit.
