Mole LRL 3000D operating manual
6
The most often used operating frequencies are:
•
Lead– 4,5 kHz
•
Gold–
5,0-5,5 kHz
•
Aluminium– 7,0 kHz
•
Silver–
8,7-8,9 kHz
•
Bronze– 11,3kHz
•
Copper-brass - 11,7 kHz
•
Diamonds– 12,7 kHz
•
Iron–
17,0-17,8 kHz
LRL3000D
is a precise digital locator for search of various metals underground.
The operating frequencies are controlled by an encoder and are monitored by a
digital display. The SENSITIVITY knob shall be put at 5 scale marks at least.
Then, the forward search distance is half of the maximum one. In most cases,
the knob should be put at (10) scale marks at the most. The sensitivity is set at
the customer's request.
LRL 3000D
digital locator has
15
built-in programs -
8
of which preset to the
most common metal search frequencies, and
7
- customized and also preset.
The operator can select frequencies different than the ones specified, except the
frequencies for
lead, aluminium, bronze, copper-brass
and
diamonds
. All other
frequencies for
gold, silver
and "
iron
can be changed within their limits. For
example: If you want to change the frequency of
gold
from 0.005000 MHz to
0.005125 MHz, turn the encoder (frequency) clockwise until the counter shows
the desired frequency. Each step of the encoder equals to 1Hz. If you turn the
encoder faster, it will jump over 10 or 100 scale marks. The other frequency shift
option is associated with a
step
shift. Press
Step
and a cursor will appear below
the scale numbers. Turn the encoder to the left and it sets down to tenths. Then,
release
Step
. From now on, each step of the encoder is multiplied by 10 Hz. Turn
the encoder to the left or right, and make sure of it.
If you press
Step
again and move the cursor through the encoder below the
hundredths or thousandths, each step of the encoder multiplies by 100 or 1000.
After making the rough adjustment, press
Step
and return the cursor below the
tenths by using the encoder and release
Step
". Each change is automatically
