Low  signal  frequency  in  the  wet  ground  allows  for  maximum  search  range  and  minimum  signal 

routed  to  other  communication  lines  or  objects  (273,  526  or  1024  [Hz]).  But  at  low  frequencies  the 
noise influence of power current and signals in adjacent lines is stronger. 

 

High frequency (“8928”) in the dry ground allows for higher search range and lower power-supply 

disturbance. Higher frequency “33k” is recommended when searching for insulated cables and lines 
with  far  ends  not  connected  to  the  ground.  In  this  case,  the  survey  current  generated  as  a  result  of 
ground leakage through distributed isolation capacitance is higher. In addition, high frequency is pref-
erable during wire-free connection of the transmitter to the objects or lines of communication (

Fig. 5

). 

 

However, it should be borne in mind that at high frequencies there is a stronger penetration of the 

signal from the transmitter to adjacent lines (objects), which may results in wrong search directions. 

 

When the transmitter is operated in combination with LKO-1500 receiver, at high density of com-

munication lines, you can use current direction sensing function. The current flow from the transmitter 
(direct  current)  or  to  the  transmitter  (let-through  adjacent  line  return  current).  In  this  regard,  set  the 
transmitter signal output at double frequency of 1024 [Hz] signaled 

↑↓

. Set operating frequency “1024” 

for the receiver. Setting the output power of the signal.  
 

 

3.4.2.3  Signal power output settings 

 

You  should  correlate  the  settable  power,  desired  search  time,  power  supply  source  parameters 

and estimated search range.  

Increase or decrease power output by pressing the buttons 

. Indicator  (pos. 5  Fig. 2) 

shows power output value. Indicator on position 6 (pos. 6 Fig. 2) shows voltage output (V) and output 

signal current value (А). Parameter can be selected by pressing the button 

 

If the desired current value cannot be obtained, check the grounding quality and / or change the 

signal frequency for the ground type. If the transmitter cannot provide the specified power, it is auto-
matically limited to maximum possible value at the given load. In case of high load circuit resistance 
when  minimum  power  cannot  be generated  (for  example,  open  load),  power  level  indicator shows  a 
message: “

-1

”. Also power output limitation may be resulted from insufficient accumulator capacity. 

 

Generally  load  conditioning  time  does  not  exceed  one  minute.  If  conditioning  is  longer,  check 

connections and ground quality, change power output or switch to continuous wave generation mode.  
 

3.4.2.4  Transmitter operation mode selection 

 

Continuous  wave  and  pulsing  generation  modes  are  available  for  the  transmitter.  Continuous 

wave generation mode is recommended when determining position of communication lines, its depth 
and during insulation troubleshooting. Pulsing generation mode is recommended when searching for 
communication line under high noise conditions or at low signal received, as it’s easier to determine 
your  own  signal  by  typical  pause  in  this  mode.  Also  the  transmitter  power  consumption  is  reduced. 

Generation  modes  from  continuous  to  pulsing  are  switched  by  pressing  the  button 

  and  dis-

played in time with output signal (the green diode is green) by indicator (pos. 12 Fig. 2).
