ENVI-MAG Manual A4-11
Setup
SEARCH MODE
The search mode is obtained (after a pressing the “SETUP” and “ON” keys
simultaneously) by selecting configuration
4-Search Magnetometer
from the ENVI Applications menu.
This mode does not store any data (that you can dump) in memory, but you can
see a graphical representation of up to the last 178 readings. This mode is useful
for rapid reconnaissance or location of magnetic objects in small areas where no
permanent record of the data is required.
There are only two parameters that need to be set for this mode— the duration
of the reading and the tuning (ambient) field value.
Sample search mode setup
1. Move the cursor to DUR
2. Select! 0.5 sec from the following list: 0.5 sec, 1 sec, 2 sec
3. Move the cursor to TUNE FIELD
4. Enter! 60000 (or whatever value is appropriate for your survey area;
please refer to Figure B-4 on page B1-14, if this value is unknown)
5. Move the cursor to AUTO TUNE
6. Select! yes
You are now ready to start looking for magnetic objects.
MODE: srch. DUR:0.5s
TUNE FIELD: 60000
AUTO TUNE: yes
