Absolute EncodingThe absolute encoding disk ensures high accuracy, efficiency and stable performance. Initialization is needless but to measure the angle immediately as the HTS-220/R is turned on.Theazimuthinformation won't bemissedeventhe HTS-220/R is power-off unexpectedly. High-performance MCUSMT32The STM32 MCU based on ARM Cortex™-M processor enables the HTS-220/R has extra high processing speed and low-power consumption.BluetoothThe Bluetooth wireless technology makes HTS-220/R accessible to any data collector for real-time communication. The third party field software such as Carlson SurvCE is fully compatible with the HTS-220/R.Data StorageDiversified data transfer options such as SD card, USB pen drive, mini-B interface.BacklightThe display and keyboard with backlight for working in the dark.Diagonal EyepieceSupport diagonal eyepiece forobservations at steep line of sight.Calibration SoftwareThe proprietary HI-TARGET Calibration software is accessible for real-time diagnosis to ensure trouble-free operation. Data Transfer SoftwareThe 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.Technical parametersAngle MeasurementMeasurement Method: Absolute EncodingMinimum Readout: 1″/5″/10″(0.3mgon/1.5mgon/3mgon)adjustableAccuracy1: 2"Distance Measurement (HTS-220 with Reflector)Single Prism:3000m (9,842ft.) under good condition3Three Prisms: 6000m (19,685ft.) under good condition3Reflective Sheet: 800m (2,624ft.)Accuracy: 2 mm +2ppmMeasuring Time (Fine/Quick/Tracking): 1.5s/1s/ 0.5sDistance Measurement (HTS-220R Reflectorless)Reflectorless2Range: 400m (1,148 ft.)Single Prism: >7500m (24,606ft.)Accuracy:3mm+2ppmMeasuring Time: 1.5sTelescopeMagnification: 30XField of View: 1°30′ (2.7m at 100m)Minimum Focusing Distance: 1.5mReticle: IlluminatedCompensatorSystem: Single-axis liquid tilt sensor/Dual-axis (optional)WorkingRange: ±3′Setting Accuracy: 1″CommunicationBluetoothInterface: Standard RS232, SD card4,USB pen drive, mini-BInternal Data Memory: Approx. 20,000 PointsData Format: ASCIIOperationOperation system: Real-time Operating SystemDisplay: High resolution backlight black and white display with contrast adjustment/ Graphics:280 x 160 pixels / Character: 6 lines x 25 charactersKeyboard: 2 sides Alphanumeric backlit crystal keyboardLaser PlummetType: Laser point, 4 brightness levels adjustment / Optical plummet (optional)Centering Accuracy: 1 mm at 1.5m instrument heightPower SupplyBatteryType: Rechargeable Li-ion batteryVoltage/Capacity: ZBA-400: 7.4V (DC) / 3000mAhOperating Time With ZBA-400: Optimal 16 hours5(Continuous angle measurement every 30 seconds) / 10 hours (typical)Measuring Times: Approx. 12000 timesWeightWeight (Incl.
