Trust your total station setup before you stake. PASS or RE-SHOOT, offline.

SetupCheck DC shows the backsight bearing and distance the gun should read. It grades the check shot. When setup fails, it gives a plain reason.

What It Checks

Known-point setup

Pick occupied, backsight, and check points. SetupCheck DC computes the inverse and grades dN, dE, dZ, horizontal, vertical, and slope residuals.

Free-station resection

Use three or more control observations. The app shows RMS, per-point residuals, and the point to verify or drop.

Scale factor direction

Enter grid scale factor and elevation. The app shows CSF and states the direction: grid = ground x CSF, ground = grid / CSF.

FAQ

What does SetupCheck DC do?

It checks the occupied point, backsight, and check shot. It also checks tolerance, resection fit, and scale factor direction.

Is it offline?

The engine works with no backend. The control list, ledger, resection solver, and exports do too.

How much does it cost?

Free for 3 setup checks. Pro is $19.99/mo, $199/yr, or $499 once. Monthly and yearly plans renew until canceled in Google Play. The $499 once plan is a one-time unlock.

Who is it for?

For solo layout techs and small crews in data halls.

What standards does it use?

It uses survey math for inverses, resection, and scale factor. Check each project tolerance before you stake.

Article Outline

Before staking, key control. Compute the backsight inverse. Shoot a separate check point. Compare residuals to the project tolerance. Diagnose HI or scale-factor faults. Log the setup before layout starts.
