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.

TRANSDUCER MOUNTING
The calibrator HD2060 presents a flat circular steel fixing base (see Figure 3.1), resis-
tant to abrasions, with a UNF 10-32 threaded hole in the center for the mounting of
the transducers.
The fixing base can freely rotate on its housing so as to avoid damage to the calibra-
tor when mounting the sensors and applying the tightening. To fix the accelerometer
using a screw it’s sufficient a 1-2 Nm tightening force, compatible with a manual op-
eration. For maximum measurements repeatability, the use of a torque wrench is rec-
ommended.
Maximum applicable forces to the fixing base are: 30 N pressure force, 10 N traction
force and 2 N transverse force (see picture 3.2). Applying a load which exceeds
specified limits can permanently damage the HD2060 calibrator.

As an alternative to screw mounting, it’s possible to fix the sensor onto vibrating base
using double-sided tape, wax or quick glue; for this can be used the supplied adapter
HD6245.1 (see picture 3.3) to be mounted between vibrating base and transducer. To

avoid an excessive pressure on the vibrating base, we recommend to glue the trans-
ducer on the HD6245.1 adapter before screwing it to the vibrating base.
Fig. 3.3: Adhesive Mounting
To calibrate axes orthogonal to the mounting axis on triaxial accelerometers, it is sup-
plied the adapter HD2060.20, complete with UNF 10-32 dual threading screw to fix
the adapter to the mounting base and screw with UNF 10-32 threading to fix the sen-
sor to the adapter (see picture 3.4).
Fig. 3.4: Use of adapter HD2060.20
If you use the HD2060.20 adapter to calibrate at 16 Hz perpendicular axis of a triaxial
accelerometer having a mass greater than 30 g, it is necessary to balance the load
using a counterweight equal to that of the transducer to be mounted, as shown in fig-
ure 3.5.
Fig. 3.5: Use of counterweights
Calibrator must be placed on a flat horizontal surface, possibly free from external vi-
brations. In order to check that transmitted vibration level from supporting surface is

negligible it is sufficient, after transducer has been fixed to the mounting base, to ve-
rify that acceleration on the measurement chain with calibrator turned OFF is below
1/5 of calibration level. For example, if a calibration has to be made at 15.915 Hz with
1 m/s2amplitude level, acceleration on the measurement chain when calibrator is OFF
should be less than 0.2 m/s2.
During calibration solicitation it’s necessary to avoid unbalances on the base, taking
care of transducer’s connection cable positioning, in order to minimize the transverse
load. Transducer should be mounted so that the load is centered on the base.

HD2060 - 8 - V1.0
4TRANSDUCER CALIBRATION
HD2060 can calibrate acceleration, velocity and displacement sensors. Emission fre-
quencies are chosen to allow an easy conversion among the three measurement units
as shown in the table below.
Frequency [Hz] Acceleration
[m/s2] Velocity [mm/s] Displacement [µm]
15.915 1 10 100
0.98 9.81 98.1
159.155 10 10 10
9.81 9.81 9.81
Selection of the right frequency depends on the type of transducer and measurement
application. For example, according to ISO 8041:2005 requirements, vibration trans-
ducers used in the workplace to evaluate vibration transmitted to hand –arm system ,
must be checked at 159.155 Hz, while those used for vibrations transmitted to the
whole body must be checked at 15.915 Hz.
Some transducers are designed for measurement at very low frequencies, and cannot
be calibrated at 160 Hz. If the application or the type of transducer don’t put con-
straints to the choice, 159.155 Hz frequency is preferable because, in addition to
higher acceleration level, provides a lower distortion and lower sensitivity to vibrations
induced from the support surface.
Procedure:
1. After the transducer has been correctly mounted on the vibrating base, power ON
the calibrator by pressing the ON/OFF key.

the desired field starts blinking, then modify it using the arrow keys.
Exit from configuration mode:
In order to exit from the configuration mode, hold down the SETUP key for at least 2
seconds.
Settings are stored in the calibrator’s internal memory and remain stored even if the
device is turned OFF. When the calibrator is powered ON, it always starts with the lat-
est configuration set.

6BATTERY
The battery symbol on the display continuously provides the charge battery status. As
the battery discharges, the symbol "empties". When the charge is insufficient for cor-
rect device operation, the symbol starts blinking and it will be not possible to activate
the emission of the vibrating base.
In order to charge the batteries, connect the SWD10 power supply to the input plug
positioned on the calibrator’s side. During battery charge, the “CHARGE” red LED is
ON. The LED will turn OFF when the charge is completed. The time necessary for a full
charge is about 4 hours.
Power supply has a dual function: supplies the device and charges the NiMH battery.
When power supply is plugged in, the battery symbol on the display, is substituted by
the symbol of a plug.
In order to preserve over time the battery capacity, it is recommended to
make a complete charge cycle at least one time every six months.
The battery can be charged and discharged hundreds times, but it loses its capacity
with the use during time. If, when the battery is fully charged, the operation autono-
my is not sufficient, it’s necessary to replace the battery pack.
As spare part use only original Delta OHM battery pack BAT-40 and proceed as fol-
lows:
•If plugged in, disconnect external power supply.
•Loosen the two screws to remove the cover of battery housing placed on the
bottom of calibrator.
•Disconnect the battery taking care not to tear the wires.
•Connect the new battery: the connector has a reference that avoids uncorrect
operation.
•Place the new battery in the housing.
•Close the battery housing tightening the two screws.
Note: dispose used batteries according to safety normatives. Don’t throw used batte-
ries in the municipal waste; do not put the batteries into contact with flames or high
temperature surfaces.
