On a VW Load cell, there are either 3, 4 or 6 gauges and a single thermistor connection. Each has to be set up as a separate channel in the data logger. In the case below there are 4 gauges and the thermistor.
- When setting up the data logger the first time, use ‘Del Sel’ to delete all the tabs but one VW sensor and 0ne Therm tab.
- Rename the VW sensor tab to the serial number and gauge number 1 by right-clicking the tab.
- Click ‘Enable Engineering Units’ and choose ‘Linear Method’.
- Input the cal factor and the zero reading from the calibration record and check the ‘Units Conversion’ box and change it to Force/Kips/and choose your preferred output units.
- When the tab is filled out, click ‘New Copy’ three times and the 3 other gauges will be created beside the Therm 1 tab.
- Click on Therm 1 and choose ‘Del Sel’ to delete the Therm 1 from that location.
- Click on ‘Add Therm’ to create the thermistor location at the left side of the tabs.
- Change the name of the tabs to gauge 2, gauge 3 and gauge 4.
(The CF and Zero Reading has to be the same on each VC tab)
- Go to the Logging Tab and enable the load cell mode and choose the number of load cells in the data logger.
- Set your Interval and Choose your start time in Logger Options.
- Set the Clock Options and memory Options.
- Once you have all those set, choose ‘Apply Settings’.
Go to the Monitor Settings to check the output from each of the data loggers.
The screen shot below does not display the proper temperature as there is no thermistor connected.
You should be able to look at each load cell independently by choosing the load cell on the drop down.
