Each one of our enDAQ sensing devices is supplied individually calibrated from the factory and includes a NIST traceable calibration at 10g-peak, 100 Hz.

Because these units are often used to measure harsh shock and vibration, the embedded accelerometer is often subjected to excessive shocks, temperatures, radiation etc. These violent environments can result in a significant change in sensitivities and even permanently damage the unit. Therefore, it is wise to make periodic verification of the sensitivity calibration. This calibration frequency depends on the application, but once every year is generally recommended for accelerometers.

Sending back your unit for recalibration will provide you with the confidence necessary to know that your accelerometer remains accurate. If the sensitivity changed significantly our enDAQ Lab software enables you to edit these coefficients for already recorded data. enDAQ will also update the firmware on the device (if there is an update available) to reflect any improvements or bug fixes. The calibrated device will be shipped back with a new roll of tape and mounting bolts, too.
