How to Use the Calibration Tool within LoadVUE Pro/SensorVUE/ControlVUE Software

Click on Tools…Calibrate Sensor in LoadVUE/SensorVUE.

The calibration program will start up, detect the attached sensors and show the main window.

(This software can be used to calibrate load cell, torque sensors, pressure sensors and displacement sensors just be selecting appropriate units.)

Select the COM port (We suggest to disconnect all other sensors except the sensor under calibration to avoid the risk of accidentally calibrating the wrong sensor)

 

 

 

 

 

The ID, calibration units and sensor capacity should be automatically detected. If not enter the correct values.

Click Select Load Direction…

The load direction window will be shown.

 

 

 

 

 

 

 

 

 

 

Select Compression Only or Tension Only if you are doing the calibration in one direction only. If you are doing the calibration in both directions you will have to do each direction one after the other.

If you have accurate weights (preferably) going up to the full capacity of the load cell you can perform

  1. A 2-point calibration, at 0 and full load
  2. If you have weights that cover intermediate points you can perform a multi-point calibration (recommended)
  3. If you don’t have any weights but have the calibration certificate from the manufacturer specifying the mVolt/V of the load cell, you can just enter the number in the mVolt calibration tab.

mVolt Calibration

Click on the mVolt Calibration tab and enter the value provided by the manufacturer and click Burn mVolts.

 

Calibration is finished! You can click on the verify tab to verify this calibration.

2 Point Calibration

If you have only one weight you can perform a 2 point calibration

Remove all load from the load cell, enter 0 as the first load (Step A) and then click Read.

Then place a known load (preferably full load) on the load cell, enter the value in Step B and click Read.

Then click on Burn 2-Point Calibration

The calibration factors will be computed and burnt into the load cell interface.

3 Point Calibration

If you have more than 1 weight (totaling up to full load) you can perform a multi-point calibration. A minimum of 3 weights (4 points, zero load and 3 known load points) is required for this operation.

In the Multi-Point calibration tab enter the 3 load points and click Read after placing each load. Then click Burn Multi-Point Calibration to burn the calibration into the device.

You can click on the Verify tab and click

Tare to zero the load cell

Start/Stop to read the load cell and verify the calibration.

 

Note:

Similar calibration procedure can be followed for Torque and Displacement sensors but just selecting the appropriate units.

Note:

1 Torque Sensors should have IDs starting with “TQ-“

2 Displacement Sensors should have IDs starting with “DISP-“

3 Pressure Sensors should have IDs starting with “PR-“
