Total Station Angle Measurement System Repair & Calibration
ServiceAngle measurement is the foundation of total station accuracy. When
encoders drift, compensators malfunction, or optical plummets go
out of alignment, your survey data becomes unreliable. Our angle
measurement system repair service addresses the complete angle
measurement chain — horizontal and vertical encoders, tilt
compensators, and optical plummet alignment — restoring your
instrument to factory angular accuracy specifications. We service
all major brands including Leica, Trimble, Topcon, Sokkia, and
Nikon. Key Features- Absolute & Incremental Encoder Repair — Glass disc cleaning, readhead alignment, signal processing board
repair for both absolute and incremental encoders
- Compensator Overhaul — Pendulum mechanism restoration, capacitive/inductive sensor
recalibration, damping system service for Leica, Trimble, and
Topcon compensators
- Optical Plummet Alignment — Precision reticle centering and collimation on dedicated
alignment bench to within 0.5mm at 1.5m
- ISO 17123-3 Verification — Full-circle angle measurement verification per ISO 17123-3
procedures, including horizontal and vertical angle uncertainty
assessment
- Multi-Axis Calibration — Single-face and dual-face measurements verified across full 360°
rotation in 15° increments
- Before/After Calibration Report — Detailed report showing angular error measurements pre- and
post-repair
Why Choose Our Angle System Repair- Specialized Encoder Lab — Dedicated clean-room workstations for encoder disassembly and
repair, preventing dust contamination
- Factory-Grade Calibration Bench — Precision collimator array with 0.1 arc-second reference
accuracy for angular calibration
- 12-Month Warranty — Full warranty on all angle measurement system repairs
- Free Diagnostic Assessment — We diagnose the root cause before any repair work begins

Frequently Asked QuestionsQ: What are signs of encoder failure? A: Angle readings drift even when the instrument is stationary,
horizontal/vertical angles jump unexpectedly, or the instrument
shows encoder error codes on startup. Q: How do I know if the compensator needs repair? A: The instrument displays "Compensator Out of Range" persistently
even on stable ground, or angle readings change when the instrument
is slightly tapped. Q: Do I need to send the tribrach for optical plummet alignment? A: We can align the instrument's integrated optical plummet without
the tribrach. However, for complete system accuracy, we recommend
including the tribrach for verification.
