Maintenance (Storage) - Velleman CSR1 Manual De Instrucciones

Remember, BE PATIENT and WORK SLOWLY. Do not try to cover too large an area. Restrict yourself to a small
area and work through it thoroughly. Make a note of the position and extent of the area, and then when you return
you can start again further on without missing any ground or covering the same area twice.
It is also important to keep the detector head as close to the ground as possible. Ideally, you should "iron" the ground
with the search head of the detector, so that you do not lose any detection range. Similarly, if you work slowly and
carefully you should be able to distinguish the faint signals as well as the clear-cut signals and increase your finds.
The technique of getting the best out of your detector is not learnt overnight. You need to get as much experience as
possible so that you can recognise every kind of signal. Indeed, a good detector operator can often tell you what is
being detected before it is unearthed.
It is essential that the search head is kept close and
parallel as in B. Do not hold the head too high above the
ground, or at an odd angle as in A, C and D as you will
be apt to miss finds.
e. Sweeping Technique
For extremely small object searching, such as coins, rings, nuggets, etc. lower the search coil to within one inch of
the ground. Sweep the coil from side to side in a straight line in front of you. Keep the coil at a constant height as you
sweep from side to side. Move the coil at the rate of one foot per second.
The optimum sweep rate must be determined by each operator. The detector should be held comfortable in the
hand, with the coil held as closely to the ground as possible. As the detector is scanned from side to side in front of
the operator, the search coil should be advanced approximately two-thirds the diameter of the coil. This keeps the
operator moving ahead, and it allows some overlapping of each sweep. This overlapping ensures that nothing will be
missed. It is well to note here that the operator should not rush. This is one of the most common mistakes made by
detector users. If you rush, you will not adequately cover the ground.
6. Maintenance
(Storage)
When not in use your detector should be stored in a dry warm environment. If it is not to be used for a certain length
of time it is advisable to remove the batteries to avoid leakage which could cause serious damage. The working life
of your detector will be shortened by careless use or neglect of the unit. Think of your detector as a scientific
instrument. Your detector is designed to withstand rugged handling on any terrain, but misuse or lack of due attention
will tell in the end. After using your detector in a hostile environment (salt water, sand, etc.), the exterior parts should
be flushed with clean fresh water, paying attention to the head and stems, then carefully wiped dry.
7. Troubleshooting
a. The detector does not operate
a) Check the condition of batteries under load. (See "3. Batteries & Battery Check")
b) Check that the search head is properly attached to the control box via the search head cable connector.
c) Interchange batteries and ensures connections are correct and secure. Battery life can vary tremendously
between makes, therefore your 'new' batteries may already be insufficiently powerful to run the detector.
