HD2060 - 3 - V1.0
1INTRODUCTION
The calibrator HD2060 generates mechanical vibration amplitude controlled with pre-
cision and frequency stabilized by a quartz. Coupling a transducer to the vibrating
base of the calibrator it is possible to check its sensitivity to acceleration, velocity or
displacement. The presence of a rechargeable internal battery, the weight and the
small dimensions as well as the low sensitivity to environmental parameters make it
easy to use the calibrator in the field. The calibrator is equipped with a feedback sys-
tem capable of accurately maintaining the amplitude level set, regardless of the load
associated with the mass of the transducer (within the limits stated in the technical
specifications).
The mechanical vibrations generated by the calibrator are very stable over the time,
with a typical drift of 1% per year. In order to maintain the accuracy, we recommend
the annual calibration at DELTA OHM metrological laboratories. The calibrator notifies
the user about the need to make the periodic check by displaying alternately the signs
"cal" and "exp" on the display.
The backlit display provides a clear indication of acceleration, frequency and the
reaching of the set level. In case of exceeding the maximum permissible load or in
case of low battery, the calibrator alerts the user by displaying an error message and
the operation of the vibrating base is turned off. The automatic stop of the vibration
after the set time and the automatic shutdown function prevent the discharge of the
battery.
The calibrator is equipped with screws and accessories for mounting the transducers,
with external power supply for charging the battery and with calibration report.
Applications:
•In-the-field calibration of acceleration, velocity and displacement transducers.
•Calibration of acceleration sensors used for the measurement of vibrations
transmitted to men in the workplace, according to the standard ISO 8041:2005.
•Calibration of acceleration sensors used to evaluate buildings vibration.
Main specifications:
•Two frequencies of emission: 15.915 Hz at 1 m/s2and 0,1 g
159.155 Hz at 10 m/s2and 1 g
•Low distortion accelerations, independent from the mass of the transducer
•Absence of dispersed magnetic field.
•Backlit display with the indication of the acceleration level stabilization.
•Internal rechargeable battery which allows 2 hours of continuous operation at
15.915 Hz and 7 hours of continuous operation at 159.155 Hz.
