Product Description
Absolute Encoding
The absolute encoding disk ensures high accuracy, efficiency and stable performance. Initialization is needless but to measure the angle immediately as the ZTS-121/R is turned on. The azimuth information won't be missed even the ZTS-121/R is power-off unexpectedly.
Dual-axis Compensation
The ZTS-121/R is configured with advanced dual-axis compensatorfor auto error elimination and auto accuracy compensation.
High-performance MCU
The STM32 MCU based on ARM Cortex™-M processor enables the ZTS-121/R has extra high processing speed and low-power consumption.
Bluetooth
The Bluetooth wireless technology makes ZTS-121/R accessible to any data collector for real-time communication. The third party field software such as Carlson SurvCE is fully compatible with the ZTS-121/R.
Data Storage
Diversified data transfer options such as SD card, USB pen drive, mini-B interface.
Backlight
The display and keyboard with backlight for working in the dark.
Diagonal Eyepiece
Support diagonal eyepiece for observations at steep line of sight.
Calibration Software
The proprietary HI-TARGET Calibration software is accessible for real-time diagnosis to ensure trouble-free operation.
Data Transfer Software
The proprietary HI-TARGET data transfer software supports different type of output data format, which can be used in AutoCAD or other brands' post processing software.
