2 How to Use the Locator
2.1 General Information
Operating modes • Passive modes: Power and Radio
• Active modes: 8 kHz, 33 kHz, additionally 512 Hz and 640 Hz on xf models
• Auto mode: Combined Power and Radio modes
Electromagnetic signals An electromagnetic signal radiates from buried conductive services as an electrical current
flows through them. The Locator processes these signals and displays their presence.
Passive signals Some signals are already present on buried services and can be readily detected by the
Locator. We call these passive signals. These signals are generated by power distribution
systems and radio transmitters.
Active tracing Some conductive services do not emit passive signals. These services may be traced by
applying a signal to the service by using a transmitter.
Depth indication
(i550, i650, i750, i550xf,
i650xf, i750xf)
Depth indication is only available with the i550, i650, i750, i550xf, i650xf, i750xf locators
when used in conjunction with the Transmitter or Sonde. The displayed depth is to the
centre of the service or to the Sonde.
Current Measurement
(i550xf, i650xf & i750xf)
Current measurement is only available on the i550xf, i650xf or i750xf when used in
conjunction with the transmitter. The highest current reading (mA) will be displayed over
the service which has the transmitter connected to it.
Wireless communication
(Bluetooth)
Data can be wirelessly transferred from the Bluetooth enabled Locator to devices which are
designed to accept the information.
