Delta OHM HD 2060 Manual

HD2060
PORTABLE MULTI-FREqUENCY AND MULTI-LEVEL CALIBRA-
TOR FOR VIBRATION TRANSDUCERS
The calibrator HD2060 generates mechanical vibration amplitude controlled with
precision 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 system 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.
