Steps Required Before Drilling
1.
Scan the jobsite for interference.
2.
Pick the frequency bands.
3.
Pair the locator with the transmitter.
4.
Verify data range.
5.
Calibrate both bands.
6.
Check Above Ground Range.
1. Scan the Jobsite
a.
With the transmitter off, select
Transmitter/FO
from the Main menu,
then
Frequency Optimization
(FO)
. The FO will show active
interference (noise) readings for current bands. Select
Scan/rescan
to see nine newly optimized bands.
1. Current bands
2. Selector
3. Band number
4. Maximum noise level
5. Up band
6. Down band
7. Scan/rescan
8. Pair
9. Exit
Frequency Optimization Results
Run the FO for each new project to select an optimal set of
frequencies for each band every time.
b.
With the FO results displayed, walk the locator along the bore path
while observing the noise readings. Mark those points where
significant increases occur.
If noise levels rise substantially at any point along the bore, consider
selecting and pairing one band (see next step) that performed well up to
this point. Cancel calibration, and select Transmitter/FO to repeat
Step 1
- Optimize
. Perform a new scan, select and pair a second band for use in
this higher-interference area.
