alignment
NB! Some external sensors may have been set up to output
data referred to a location that differ from where it is physically
mounted. It is the x, y, z values for this location that must be
entered into the EM 710 Operator station.
8.1 Summary
The minimum requirements for alignment accuracy are given for
the various sensors in the following tables
WARNING
System performance will be reduced if the
requirements are not fulfilled. The calibration
value should not exceed the measurement
accuracies stated below.
