10. 2 Available transmitter clamps Although transmitter and locator clamps look the same they have different internal windings To prevent the wrong clamp being connected transmitters and locator clamps have plugs of a different orientation Standard signal clamp The standard clamp applies the transmitter signal very selectively and effectively to a target cable up to 100mm 4 diameter at frequencies from 8kHz to 200kHz The standard and small clamps have a double spring action for positive toroidal contact Small signal clamp The small signal clamp is useful for applying a signal to a target cable in a pedestal or other place with limited space The clamp is suitable for cables up to 50mm 2 diameter and can also be used for frequencies from 8kHz to 200KHz A WARNING The transmitter must only be connected to live services using the appropriate accessory such as a plug connector or live cable connector 7 4 Sondes 7 4 1 When to use a sonde A sonde transmitter is a small battery powered signal transmitter that can be inserted into non metallic ducts drains or sewers so they can be located and traced with a locator A wide range of transmitting sondes is available to suit different applications Sondes can also be used to pinpoint joints in iron gas pipes locate blockages in plastic water pipes and monitor the progress of horizontal boring tools 7 4 2 Choosing a suitable sonde Check that the sonde has sufficie
