Explore the depths of the next, move the electrodes on constant relationship (AB/2) 2 > 5 MN at any depth at all levels in this exploration phase and AN MN moving on in.
Exploring the depths Next. To move the electrodes to the constant relationship 2 (AB / 2)> 5 MN at all depths. In this survey, MN and AN-term move in the table.
The depth of the next. The move electrodes out according to constant relationship 2 (AB / 2) > 5 MN throughout all the depths in the survey period and move MN AN. According to the schedule in the picture.
