The following menu gives you access to some of the parameters in the set up menus.
• A-position - Will take you to the position coordinates setup screen. NOTE that from this menu
you can only change the coordinates but you cannot change the system (see section 5.3.2).
• B-enter text - Allows you to type messages or comments which can later be recovered with
SEND.
• 4-graph - Is active only if graph mode is selected. It allows to change the graph's scale and
offset (see section 5.3.8)
• C-tune - Leads you to the tuning setup screens (see section 5.3.6). NOTE that the tune initialize
process is not repeated when returning to survey (even when set to YES).
• 5-display-mode - Guides you through the selection of Display Mode (see section 5.3.8).
• E-EOL - Performs End Of Line function - line number is incremented, direction is reversed
(see section 5.4.4).
• F-ok - Takes you back to survey.
• 0-noise - Will display noise from sensor - value of 100 or less is normal (see section 5.4.3).
• 1-info - Is very useful in providing information about last reading like s/n (signal/noise ratio)
and measurement time in ms. It also shows the number of readings which can be taken before
the memory is full (see section 5.4.5).
