QUESTIONS & ANSWERS
This unit is certified to ISO 9001:2015, ISO 10012:2003, ANSI/NCSL Z540-3-2006 (R2013), and ISO/IEC 17025:2017 calibration standards. A Certificate of Calibration is included with each KS6005-WC PRO 3600 Digital Protractor at the time of shipment. This ensures traceable accuracy and compliance for aviation and precision measurement applications.
The KS6005-WC PRO 3600 Digital Protractor is used to measure angles with high precision across a full 360° range. It is commonly used in aviation, maintenance, machining, and inspection applications where accurate angle measurement is critical. The digital display provides quick, reliable readings in both field and shop environments.
This digital protractor provides a full 360° measurement range, divided into four 90° quadrants for easy readability. It can measure both positive and negative angles, making it suitable for a wide range of alignment and leveling tasks.
The PRO 3600 offers high accuracy, with ±0.05° near level and up to ±0.2° across its full range. It also delivers repeatability of ±0.05°, ensuring consistent results across multiple measurements.
The unit features a resolution of 0.01° when measuring near level (0° to 9.99°) and 0.1° at higher angles. This allows for extremely precise readings when fine adjustments are required.
The PRO 3600 includes a HOLD function to freeze readings and an ALT ZERO feature to set a custom reference angle. These features make it easier to capture measurements in hard-to-read positions and to perform relative-angle calculations. The digital LCD display provides clear, easy-to-read results in real time.
Yes, the PRO 3600 can be recalibrated in the field using the built-in Superset® procedure. This process does not require special tools or fixtures and can be completed in just a few minutes. It allows technicians to maintain factory-level accuracy without sending the unit out for service.
Yes, the KS6005-WC PRO 3600 features an RS-232 compatible serial interface for data output. This allows angle measurements to be transmitted to computers, printers, or data logging systems for documentation and analysis.
The PRO 3600 features a precision-machined aluminum frame that is both lightweight and highly durable. The base includes grooves for measuring on round surfaces, such as pipes or shafts, as well as threaded holes for secure mounting.
This unit operates on a standard 9V battery, providing up to 500 hours of typical use. It also includes an automatic shutoff feature to help conserve battery life when the unit is not in use.
