The CT-EW1 Step Calibration Table was originally conceived by Prof. Erhard Wielandt. LE turned it into a marketable product, adding several minor enhancements in the process.

The CT-EW1 can be used to determine the transduction factor (x V/m/s) of broadband sensors in a reliable, repeatable manner. Actually its use is not limited to broadband sensors, it can be used equally well for short-period sensors or accelerometers, but for these types of sensors there may be more direct methods available for determining x.
