Displaying stabilizing time: .10s during swaying angle.±2° 2). Non-linearity parabolic modification 3). Auto zero-point and minus tare weight point tracking 4). Tare function: Tare can be weighed or preset. Tare range is set to be between 0-Max. There are different annunciators corresponding to Net Weight, Tare and Gross Weight states. 5). Minus weight function 6). Power-saving function. Entering power-saving mode 30 seconds after weight is stabilized. 1 wireless digital transmission every 5 seconds. Powering off automatically 30 minutes after no any fluctuation in weight. 14. Operating Environment Operating Temperature Indicator: 0.~40. Body: -20.~40. Storing and Transporting Temperature -25.~55. Relative Humidity .85%RH 15. Dimension 330 x 230 x 60 (mm) Weight around 1.5kg II Configuration, Installation and Application The wireless electronic crane scale is mainly composed of scale body and indicator, accessories like charger, cable, are also supplied. 1. Configuration of the scale body This part is makes up of weighing load cell, carrier and transmitting mechanism, case, A/D module, wireless digital transmitter, battery, etc. 2. External layout of indicator Micro-printer LCD Screen Keypad Antenna (Figure 2) Front layout Printer Port RS-232/422/485 Signal Cable Power Switch Charger socket Scoreboard Interface Calibration Switch (Figure 3)Rear Wiring Layout 3. Wireless working mode: Usually, XK3190-H2B Indicator is used in wireless transmitting electronic crane scale. Install the transmitting antenna before operation, and then open the small cover on the scale body to install the battery, after inserting battery plug into the battery socket and turning on the switch, the annunciator begin to twinkle, indicating the electric circuitry of the scale body in working state. The crane scale will go into the power-saving mode and twinkle once every 5 seconds when it has been out of operation or the weight on the scal...
