sufficient, part of the output current is branched into the remote areas of buried utility. The
serviceability is maintained till full short-circuit of the output clamp.
When selecting the load current (or power) and frequency of the transmission the following
guidelines are to be followed:
-
the lower is the power – the higher is power supply life
-
the lower is the current, the lower is the frequency – the lower «induction» on the
neighboring elements
-
the higher is the frequency – the higher is sensitivity of receiver, the less current
(power) is enough, energy saving is possible, recommended for high-resistance buried
utilities, on the other hand, the higher level of signal penetration into the neighboring
objects and, as a result of higher attenuation, the signal is spread at the less distance.
-
the higher is the current, the lower is the frequency – the range of transmission and
route detection is higher, but the power required is higher.
3.6 Modification of the set parameters
To modify the set parameters, stop the generation with the button « » pos.10 figure 3.9
at the field «OUTPUT» by one or two depressions and proceed to the
parameter’s setup. The
first depression of the button « » pos.10 results in stop of the automatic matching process
at the achieved level (the indicator readings are “frozen”, no generation, yellow LEDs on the
field «OUTPUT» are not on), second depression on the button « » results in the stop of
generation (the indicator is off).
To enter the parameters modification mode depress the parameters setup button « »
pos.5 while staying in the «stop» mode. The indicator field «MODE» will start blinking, to
change the mode use the buttons « » or « » (by cycle) pos.5 to select the required
generation mode symbol and go to modification of other parameter (frequency, current) with
buttons « » or « ». The blinking value of parameters from the databank can be selected
with buttons « » or « » (
0…9). To modify the parameter value when the required
value is not in the databank (the selected parameter blinks) depress the parameter setup
button « », after that the blinking figure can be modified with buttons « » or « »
(0…9). To save the new value in the data “bank” (instead of the previous one) depress the
button « ».
3.7 Indication of parameters
1)Indication on the field «POWER» figure 3.10.
One of the digital indicator readings is selected by the corresponding button pos.3 by
the green LEDs.
