All CTC & TMP Line vibration sensors include a free CA10 calibration certificate upon shipment. The CA10 certificate is a single point calibration at 100 Hz, NIST traceable. Multi-axis sensors will receive a CA10 calibration for every axis. All CTC WS Series ConnectSens wireless sensors receive a free CW10 calibration certificate upon shipment. The CW10 is a single-point step calibration for wireless sensors at 100 Hz and a single-point temperature calibration at 20 °C. For triaxial wireless sensors, the 100 Hz calibration is performed on the Z axis.
