The ADC-10 Anderon oscillator outputs a reference signal equivalent to the output from the sensor to enable calibration of the Anderon meter display unit. The ADC-100/VVU-100 Anderon vibration generators generate a reference vibration equivalent to Anderon vibration to enable calibration of a velocity sensor and Anderon meter display unit at the same time.
It's impossible to create bearings that can be guaranteed to provide consistent measurement results for extended periods. However, you can select multiple bearings for daily testing and use them as master reference bearings for maintaining and managing your Anderon meter and for confirming its condition based on comparisons of daily measurement data.
