Creating a benchmark
1.
B 2.
Place the GPS antenna in a known, repeatable location that will not change throughout
the leveling of a field.
Tip – Mark this location with flags or some other marker so that you can return to the exact spot.
3.
Stop the vehicle.
Tap Bench on the WM-Survey tab.
Note – If the FieldLevel II plugin is installed, you can tap Bench on that instead. Both Bench
buttons have the same effect.
4.
A countdown timer runs for 30 seconds and then the system creates the benchmark. To
stop the averaging during the countdown, tap Bench again.
Note – If you are within the circle around an existing benchmark, a new mark is not created.
Rebenching
When you are within the circle around an existing benchmark, the following message
appears on the Run screen:
If you tap either of the Rebench buttons when the receiver is within the circular radius of a
benchmark, the receiver is calibrated over the existing benchmark.
Re-establishing a benchmark
In the FieldLevel II configuration, under the Relative Heights tab, there is an option to Force
Re-Bench. If you plan to use the same base receiver setup each time you use this survey data,
you can set the option to No.
However, if you plan to shift the location of the base, set this option to Yes.
