TROUBLESHOOTING contd...
The ram size varies from the load cell size
This causes bending of the distribution plate which in turn causes over or under measurement
of load depending on the ratios on the cell to jack area. There are two feasible ways to
overcome this:
-
i) Match the cell and jack ram sizes to each other. This is perhaps not the easiest solution as
they will often have to be what is available.
ii) Make sure that suitably thick distribution plates are being used so that load will be distributed
to the load cell as a UDL (Uniformly distributed load).
VW Load cell is giving unstable readings
•
Are the readings alright with a different readout? If yes then suspect low battery
•
Are the strain readings outside the range of the load cell (overloading)?
•
Is there a source of electrical noise nearby such as a generator or motor?
•
Is there any significant temperature effect?
•
Is the correct swept frequency being used (readout or data logger)?
Manometer
•
Where manometer fitted check for damage Check for leaks on the cell
