CAUTION!: Failure to comply with safety cautions can result in damage to equipment or property

WARNING! Direct connection to live conductors is POTENTIALLY LETHAL and should only be done by qualified personnel using the relevant products that allow connections to energised lines.

WARNING! The transmitters are capable of outputting lethal voltages. Take care when applying signals to to any pipe or cable and be sure to notify other technicians who may be working on the line.

WARNING! this equipment is NOT approved for use in areas where hazardous gases may be present.

WARNING! Always ensure that the Transmitter is OFF when connecting and reconnecting cables.

MAX V Function

The MAX V function on the TX Transmitter is used when there is a need to locate over long distances on high impedance target lines such as lines that are unterminated, to a maximum of 90V in Direct Connect mode.

By default the setting is always set to LOW when the unit is powered on.

It is advisable to always start locating in the low voltage mode.

Consider also using a slightly higher frequency if more current is needed over long distances, before switching to the high voltage mode.

There are 2 levels of settings in the MAX V Menu.

  • LOW up to 30V
  • HIGH up to 90V

All Tx Variants have this feature. TX -1, TX -5, TX-10, TX -10B.

Note: The voltage limit should be set to LOW in the MAX V menu if using with a Flexitrace, and with the output power set to a maximum of 1W.
