Operation
Search mode
The search mode is useful for small areas where simple targets can be located
immediately, without data plotting and interpretation. Examples are paved-over
utility covers or valves etc. Due to the possibly small physical size of the target it
is necessary to use the highest sampling rate and slow sweep rate. The total-field
sensor or the base-station sensor can be used. You will need to specify which one
you are using.
Basic
Press the “ON” and “SETUP” keys simultaneously to get the configuration menu.
Select configuration
4-Search Magnetometer: This is described under
“Configuration menu” on page A4-3. You then can follow the setup as described
under “Search Mode” on page A4-11. You only need to enter two values before you
start:
▲ the duration of the reading (typically 0.5 sec)
▲ the tuning field value
Advanced
This procedure gives you the same results as using the basic mode described
above. Press the “SETUP” and “ON” keys simultaneously to get the configuration
menu. Select one of the advanced configurations (5-7). This is described under
“Configuration menu” on page A4-3.
Proceed as shown in the following steps to change the four setup parameters,
and to verify other setups as shown in the “Instrument setup” on page A4-12.
1. Line and Station number, as well as, separation are not needed or used.
2. Do the “Instrument setup” on page A4-12 as shown, except set:
▲ CYCLE REPEAT: to no
▲ CYCLE DELAY: to 0
3. Do the “Sample base-station setup” on page A4-20 as shown, except set
▲ DURATION: to 0.5 sec
