Survey Equipment Error Codes

70 error code fix guides organized by brand. Jump to your instrument manufacturer and find your error code.

An error code on a rotary laser, pipe laser, or total station is the instrument telling you exactly what failed — usually leveling range, calibration, temperature, or battery. Look up your code below for the meaning and the field fix, covering Topcon, Spectra Precision, Leica, Bosch, and CST/berger instruments.
