CONDITIONING & CALIBRATION
Why do you need to condition the FlexiForce sensor?
You should always condition the sensor prior to testing because the sensor’s output changes the first few times it is
loaded. By loading the sensor before your calibration, you will ensure that the sensor is producing repeatable results for
your calibration and testing. It will also produce a repeatable drift curve. You can condition the sensor by loading it at
110% of your maximum load for a few cycles.
How much error is induced if the sensor is not conditioned
?
The error could be greater than the standard ± 5% error if not conditioned prior to testing. You should always condition
the sensor prior to use.
What is the maximum period of not using the sensor before you have to recondition it?
You should recondition the sensor if you haven’t used it in several weeks. Please note that the more you recondition it,
the better it should perform.
Why do I need to calibrate the sensor?
Calibration is a very important step. There is a slight variance between sensors, which calibration corrects. When
performed in an environment similar to that of the test environment, calibration helps improve repeatability and neutralize
drift.
How long must the sensor be unloaded before you load it again
?
There is no exact or estimated time.
Is “110%
of the maximum load” what the sensor can handle?
Typically, the answer is “no.” The mechanical properties of the different force range sensors are very similar. The
polymer materials of which these sensors are composed will start to deform plastically around 8,000 PSI.
