Product Name: High Accuracy Laser Total Station in Survey for Construction Same as Sokkia Set Model NO.: ZTS-320R Horizontal Line: 2 Vertical Lines: 2 Accuracy: 1mm Method: Absolute Code Minimum Reading: 1'' Angle Accuracy: 2'' Magnification: 30X Field of View: 1.30' Shortest Focus Distance: 1.5m Reticle: Illuminated Single Prism: 3000m Three Prisms: 6000m Reflective Sheet: 800m Trademark: Hi-Target Transport Package: Carton Box Specification: CE/ISO/FCC Origin: China HS Code: 90151000 Product Description High Accuracy Laser Total Station in Survey for Construction SAME AS SOKKIA SETSystem Features:Absolute EncodingThe absolute encoding disk ensures high accuracy, efficiency and stable performance. Initialization is needless but to measure the angle immediately as the ZTS-320/R is turned on. The azimuth information won't be missed even the ZTS-320/R is power-off unexpectedly. Dual-axis CompensationThe ZTS-320/R is configured withadvanceddual-axis compensatorfor auto error elimination and auto accuracy compensation. High-performance MCUThe STM32 MCU based on ARM Cortex™-M processor enables the ZTS-320/R has extra high processing speed and low-power consumption.BluetoothThe Bluetooth wireless technology makes ZTS-320/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-320/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 MeasurementMethodAbsolute CodeMinimum Reading1″Angle Accuracy2″TelescopeMagnification30XField of View1°30′Shortest Focus Distance1.5mReticleIlluminatedCompensatorSystemSingle-axis liquid-electric tilt sensor CompensatorWorking Range±3′Setting Accuracy1″Distance measurementReflector (IR)RangeSingle Prism(Atmosphere general / good / best )2000m/2500m/3000mReflector(60mmx60mm)800mAccuracy (Fine/Coarse/Tracking)2mm±2ppmMeasurement TimeRepeat1sTracking0.6sReflector-less (RL)RangeWhite Target board350mSingle Prism>7500mAccuracy(short distance/tracking/prism)3mm±2ppmMeasurement Time(short distance/tracking/prism)2sGeneralCommunicationInternal Data Memory20000 PointsInterfaceStandard RS232 port (USB port / Bluetooth optional )Data FormatASCIi(DXF/GSI optional )Operation systemReal-time English operating systemDisplayGraphics:192*96 pixels ,6 line*12 characters KeyboardAlpha-numerical keyboardLaser plummetTypeLaser Point, Brightness Adjustable in stepsCentering Accuracy1 mm at 1.5m instrument heightPower supplyBattery TypeLithium-IonVoltage/CapacityZBA-400:7.4V 3000mAhOperating time with ZBA-40016 hours24 hous (Continuous Angle Measurement )Weight (Incl.
