This command allows you to set operating tolerances. There are different settings depending on whether you are configured for GPS or Total Station use. The first figure below shows the Tolerances for Total Station dialog and the second figure in this section shows the Tolerances for GPS dialog.

Total Station Configuration

• H. Obs:  This specifies the horizontal observation tolerance as an angle field. A tolerance of zero is not allowed.
• V. Obs:  This specifies the vertical observation tolerance as an angle field. A tolerance of zero is not allowed.
• Edm tol (mm):  EDM fixed tolerance in millimeters specifies the EDM error that is independent of the length of the line measured
• Stakeout Tol:  This specifies the maximum difference between the target location and actual staked point. When the staked point is beyond the tolerance, SurvCE displays a warning dialog. The Stakeout Tolerance is systematically applied to all stakeout commands.  The program will respond with a warning screen such as “Stakeout is beyond the Tolerance Setting.  Do you wish to continue storing?”  The angle and distance tolerances are applied to multiple distance measurements (when Configure Reading specifies multiple “Num Dist Readings”) and when multiple angle measurements are taken in Set Collection or processed in Process Raw File.

GPS Configuration

• CEP/HRMS Tol:  A measurement of accuracy defined by the radius of the circle containing 50 percent of the individual measurements being made, or the radius of the circle within which there is a 50 percent probability of being located.
• SEP/VRMS Tol:  A measurement of accuracy defined by a sphere within which there is a 50 percent probability of locating a point or being located. SEP is the three-dimensional analogue of CEP.
• Stakeout Tol:  This specifies the maximum difference between the target location and actual staked point. When the staked point is beyond the tolerance, SurvCE displays a warning dialog.

Note: CEP tolerance and SEP tolerance are only used by Novatel Radian and Radian IS.  All others refer to it as HRMS and VRMS Tolerance.

Note: Even if you are fixed, if you attempt to store points and your GPS tolerance values are exceeded, you will obtain a warning screen.
