    5 m/s2, 10 m/s2 and 20 m/s2 (RMS). And has 7 vibration frequencies: 15.915 Hz, 40 Hz, 80 Hz, 159.15 Hz, 320 Hz, 640 Hz and 1280 Hz. (See combinations available in 8.1). The CV211 vibration calibrator has rubber pads in order to insulate it from vibrations transmitted through the contact surface.

    6. OPERATION Before beginning the verification process be sure that the accelerometer is correctly fixed to the shaker’s head. To ensure this you can use some stud bolt adapters with different metrics supplied together with the calibrator. Magnetic and adhesive fixing is allowable only for estimate calibrations.
  • Page 9 CV211 User’s manual If you wish to modify one of the values press buttons “f-“ and “f+”, to select the 7 available frequencies, or buttons “a-“ and “a+” if you wish to modify vibration magnitude. The latter parameter will depend on the frequency chosen, since the 5 vibration magnitudes (RMS value) on the calibrator are not available for each one of the frequencies.

    6.1.1 Verification of VC431 vibrometer a) Place the accelerometer in the head of the CV211. It will suffice to press the accelerometer against the calibrator head with the hand. Although it is advisable to connect the accelerometer with a screw or by using a mounting magnet.
  • Page 11 CV211 User’s manual It is very important to fix the accelerometer on the base of the head symmetrically with regard to the vibration head, since wrong layout or placement will cause the vibration of the system to deviate from the axis.

    To charge the battery, connect the supplied mains plug adapter to the charge socket at the side of the case of the CV211 calibrator. The battery indicator is located in the upper left hand corner of the display. If the level indicator is full, the battery level of calibrator is optimal.
