Page 5: Safety
Safety WARNING This equipment is supplied by voltage which can cause an electric shock injury. Before removing the instrument from it’s housing, switch the instrument off, isolate it from the power supply and make sure that it cannot be connected inadvertently by other persons. This instrument may only be used when housed within another enclo- sure, e.g. -
Page 6: Introduction
The WI-105 latest technology to ensure fast and accurate weight readings. The WI-105 has a 5 1/2 digit (-199999 to 199999 counts) bright red LED display. It is designed for mV inputs from load cells, strain gauges & strain pressure transmitters. This compact panel mount instrument has an industry standard DIN 48 x 96 housing. -
Page 7: Installation
Installation Overall Dimensions O-ring sealing gasket supplied as standard. Panel Cutout Fastening Clips The fastening clips supplied may be fitted on the side or the top/bottom of the instrument. Ensure that the To gain access to the PCB, switch clip and screw is mounted as power off and remove terminals shown here. -

Wiring, Links, and Fuse Replacement Be sure all cabling has adequate strain relief. -
Page 9: Display And Controls
Display and Controls Keypad During Configuration Mode Keypad During Normal DisplayMode The instrument may be reinitialized at any time, with factory default Cold Start / Restoring settings restored. To achieve this, switch the instrument off. Press and Factory Settings keep pressing the right two most keys while powering up the instrument. Release the keys when COLD appears on the display. -
Page 10: Setup And Calibration
Setup and Calibration This instrument offers an easy and straightforward way to precalibrate and field calibrate the load cell system. Follow the steps below: There is only one user selectable link, the excitation link. The default Step 1: Selecting setting is for 10V excitation, which is suitable for most applications. Note Excitation Voltage that the precalibration feature only works with the 10V excitation. -

Example 2 For a 3 x 1000 lb capacity load cell system with 2mV/V each. Program the instrument as follows: - Go to the Ser and Pre.C menu. - After Volt appears, set 2.00 for mV/V sensitivity. - Set decimal point to 0000 (no decimal places). - Set SF.1 to 0. -
Page 12: Step 7: Protecting Service Parameters
DO NOT change these parameters. It is suggested that these parameters be noted for future use, especially if the instrument is replaced. These parameters can be reentered into the new instrument, with the result that reasonable accuracies can still be obtained without redoing a field calibra- tion. -
