DI-1000UHS-10K High Speed USB Load Cell Interface User Guide


DI-1000UHS-10K High Speed USB Load Cell Interface is used to capture dynamic force information at high sampling rates. Examples of such applications include failure strength testing, impact force measurements, vibration testing and material characterization. It can be used with with any resistive load cell.

Data Capture

Please follow the instructions on the software user guide to capture impact data.

Load Cell Calibration

We recommend that every load cell be recalibrated at least once a year, more depending upon usage. If your unit has been shipped with a precalibrated load cell, we suggest you ship the unit back to us for a certified calibration. However if you can apply known loads to the load cell (preferably full load), it is very easy to calibrate the DI-1000UHS-10K interface.

  1. With no load on the load cell, adjust the R1 offset potentiometer (pot) to read approximately 0.5 V between pins 5 and 8.
  2. With full load, adjust the R2 (pot) to read approximately 4.5 V between pins 5 and 8. This will also change the offset setting made in step 1, which will now be slightly different from 0.5 V
  3. Take the load off and adjust R1 pot.
  4. You may have to go back and forth a few times between steps 1 and 2 to get the desired readings at both zero load and full load.
  5. For example, for a 3000 lb capacity load cell, if the load at 0 lb. is measured to be 0.494 V and at 3000 lb is measure to be 4.653 V, then
    lb. / volt = 3000 / (4.653-0.494) = 721
    You will need to enter this number in Select/Configure Sensor option of LV-1000HS-10K software, as shown below.

Note: Pin 8 is used to connect and ground the shield of the load cell, if one is present, as well as to read the output voltage during calibration. Please connect a wire if necessary to pin 8 to read the voltage between pins 5 and 8. Once calibration has been performed, this wire can be removed.

Writing your own software for DI-1000UHS-10K

The unitís architecture is built around Measurement Computing BTH-1208LS Wireless Multifunction DAQ device. You can write your own programs to access the device through several languages and environments such as LabView, Java, .NET languages, Android etc. You can find the specifications, API and programming assistance for BTH-1208LS at Measurement Computing web site.
