All Elsys data acquisition cards and devices are delivered with a calibration certificate. All internal measuring equipment used for the preparation of this certificate has been periodically checked by an accredited testing laboratory. Thus, the accuracy of the certificates is guaranteed.


Only high quality electronic components are used in Elsys data acquisition products. However, these also exhibit some aging, which can have a negative effect on the accuracy of the measurement. Therefore, we recommend periodic calibration of the equipment – at least every two years.

Unlike accredited test laboratories, we test also transient response and clock rates precision in addition to offset and gain errors.
