TUNE
(cont’d)
Fixed tuning may be more appropriate in areas of large
cultural electrical noise, or very narrow, but large,
anomalies. These may pull the tuning away from the
desired frequency to that of the interfering frequency or
to tuning field values greatly different from the
background values.
As the setting of this parameter depends upon your
particular survey conditions, it is not possible to suggest the
best setting. The mode should therefore be established by
experimenting. However, in general, it is more applicable to
use fixed tuning for the
site characterization and drum
location
configurations.
TM/DT
This option allows you to set the time and date of your
ENVI-MAG.
You must press the “ENTER” key.
A pop-up window will be displayed showing the current
values of TIME and DATE in your instrument. Use the
arrow keys to move the blinking cursor to the field you
wish to change. Press “ENTER” again and enter the
value from the keypad. Finish the entry by pressing
“ENTER” one more time.
To get back to the main menu, press the “ESC” key.
NOTE: If you will be using a base-station to correct the
data, you must ensure that the date and time of both
units are the same BEFORE you start collecting data.
OUTPUT
This option dumps your data to a computer via the serial
port. The communications mode is fixed to 9600 baud, 8

You must press the “ENTER” key.
An information pop-up will be displayed telling you to
press the “START” key when you are ready. You must
