6 Using the vLoc-5000
Page 39 of 57
This receiver provides a wide range of frequencies for active location. Some will be the same as the
frequencies provided by the Vivax-Metrotech’s transmitter, others will be frequencies used in other
manufacturers’ transmitter.
The choice of frequencies when using induction or the clamp is restricted due to the requirement that these
modes be tuned for specific frequencies (or range of frequencies). The full range of frequencies is available in
“Direct connection” mode.
For frequencies below 45 kHz, authorities such as the FCC allow higher power output to be used; for
frequencies of 45 kHz and above, power output for this type of equipment is restricted to 1 watt. Therefore
more power is available when lower frequencies are used.
6.3
Applying the Transmitter’s Signal
The transmitter’s signal cable is applied in any one of the three ways:
6.3.1 Direct
Connection
This is used on pipes or cables that are not live and do NOT carry hazardous voltages. The “Direct
connection” mode will be selected automatically when the connection leads are plugged into the transmitter.
WARNING
Never make a direct connection to live cables carrying hazardous voltages.
Do NOT plug the connection leads into the transmitter before connecting to the buried line and fixing the
ground stake.
Take the ground stake and push firmly into the ground and connect it to the black connection lead.
To make the signal travel further along the buried line, ensure to place the ground stake as far away as
possible, and at 90 degrees to the line. Where practical avoid having other buried lines between the ground
stake and the target line, this will reduce the chances of the transmitter signal coupling to another pipe or
cable.
Do NOT connect the black lead to any other metallic items that may have an above or below ground
structure, or to any other pipes or cables; connecting to such items would cause signals to radiate from these
secondary structures, which in turn will increase the likelihood of an incorrect locate.
Connect the red connection lead to the target line after removing any surface corrosion.
Plug the connection leads into the transmitter switch on and select the desired frequency.
