C - change
toggles between
yes
and
no
•
If you select
tune initialize yes
, the unit automatically scans through its range for the initial
tuning setting. This scan is performed only once and before a reading is taken (when entering
the survey mode from this screen). Once tuning is initialized, the value of the tuning parameter
depends on the auto-tune setting.
NOTE
The automatic scanning process may fail in noisy or high magnetic gradient
areas. In these cases you may use manual tuning by setting tune initialize to NO.
•
If you select
tune initialize no
, you must manually set the field range in screen 24.
To store your selection and access the next tuning parameter, press
F-ok
.
SCREEN 23
