1.0 Introduction

This guide is designed to assist the user in the proper operation of the ReferenceMate

portable reference source (handheld shaker). Further information is provided on the use of

accessory items.

2.0 Description

The ReferenceMate portable vibration reference source enables users in the field to easily

verify sensor performance and the integrity of the cabling between the sensor and read-out

equipment, either online or portable units.

A built-in reference accelerometer assures that a 1 g test level is maintained for a unit under

test (sensor and mounting hardware) weighing up to 250 grams.

Frequency of operation and measurement types (peak/RMS) are

selected with front panel push buttons.

•61.4 Hz for imperial measurements, where 1 g is equal to 1 inch

per second (ips), ideal for use with velocity sensors

•100 Hz to confirm accelerometer performance at the same

reference frequency used by most manufacturers

•159.2 for metric measurements, where 1 g is equal to 9.81

m/sec2and 9.81 mm/sec.

A bottom-mounted D-ring belt clip is included for hands-free transport between locations

when in the field. The belt clip can be removed and replaced with a 70 lbf pull force magnet

(optional) for attachment to metal structures for hands-free operation.

LEDs notify the user when the battery condition falls below operational levels or if the unit

is overloaded. Reference test points are provided to test and check calibration of the

shaker’s internal accelerometer.

3.0 Applicable models

The manual covers the model GV2510 handheld shaker included in the REF2510 and

REF2510R kits, and the use of applicable accessories, both standard and optional.

Operation

Below are numbered steps to follow for operating the GV2510. Each step is described in

detail in section 5.2.

WARNING: The GV2510 is NOT certified for use in hazardous environments.

5.1

Operating steps

Please refer to Figure 2 for details.

1. The ReferenceMate is provided with a mounting head that accepts a 1/4-28 mounting

stud. Attach the unit to be tested (UUT- accelerometer, piezovelocity sensor, etc.) to the

ReferenceMate mounting platform, making certain to only hand-tighten the

accelerometer to no more than 10 in-lb (112 N-cm). If the accelerometer has something

other than a 1/4-28 mounting thread, use the appropriate adaptor outlined in Table 2.

The appropriate mounting torques for adaptors used with the GV2510 are also shown in

Table 2. An open end wrench is provided to stabilize the shaker head and make certain

the mounting platform (shaker head) is not excessively torqued. Over torqueing the

shaker head can result in permanent damage to the shaker suspension system. To

stabilize the shaker head during accelerometer attachment, slip the open end of the

wrench over the flats provided on the shaker head.

2. Once the UUT (and any mounting accessory) is mounted to the ReferenceMate head,

connect all cables from the UUT to the readout equipment. You are now ready to test

your device.

3. Press the ON/OFF button to initiate the 1 g test cycle. The OOR indicator (out of

range indicator) will come on momentarily as the control circuit stabilizes to a 1 g test

level. The shaker will shut off after approximately 90 seconds.

Allow at least three seconds for the GV2510 to achieve the controlled vibration level.

Observe the BAT and OOR LEDs and make sure they are not illuminated. If the BAT

indicator remains on, or if the unit will not stay on after releasing the ON/OFF switch, replace

the batteries and try again. If the OOR LED illuminates, the maximum load has been

exceeded. The excessive weight must be removed, otherwise a 1 g test level will not be

achieved.

To defeat the auto shutoff feature and enable continuous operation, press and hold the

FREQ button while turning the unit on. After the unit turns on, all three frequency LEDs will

briefly illuminate to indicate the shaker is in CONTINUOUS operating mode. The

ReferenceMate will now continue to operate until the ON/OFF button is depressed again.

This feature may be useful when the ReferenceMate is connected to an AC supply, such as

in a laboratory environment. See Section 6.1.

When the unit is turned off, it will revert to the AUTO-OFF mode.

4. Once the GV2510 has been turned on and stabilized, a frequency LED and

measurement type LED will illuminate. They will indicate the choices made when the

shaker was last turned off. To change the frequency (61.4, 100.0 or 159.2 Hz), press

and release the FREQ button. The frequency LED will toggle through the above three

choices each time the FREQ button is pressed. To change the measurement type,

press and hold the FREQ button for approximately 5 seconds. The measurement type

will toggle between RMS and Peak each time the FREQ button is pressed and held this

way.

5. To turn the ReferenceMate off before the end of its autoshutdown cycle, press the ON/OFF

button.

Operational details

Once the UUT has been mounted on the ReferenceMate and a 1 g test level has been

achieved, you can check the output of your sensor.

Table 1 shows the relationship between acceleration, velocity and displacement at the three

test frequencies. If taking imperial measurements (US) use Table 1a and select 61.4 Hz as

your frequency. 1 g (acceleration) at 61.4 Hz is equivalent to 1 in/sec (velocity). If Peak

measurement type is selected, both acceleration and velocity will be peak levels.

Conversely, if RMS is the measurement type, then both values will be in RMS.

5.2.1 Mounting

The UUT can be attached directly to the shaker head using a 1/4-28 stud. Adaptor studs and

plates are available for mounting sensors with different size mounting threads. See Table 2

below.

NOTE: The stud or adaptor plate should be mounted

finger tight only, not exceeding 10 in-lb (112 N-cm) into

the shaker head. Exceeding the maximum torque may

damage the shaker. It is recommended to use the open

end wrench when mounting sensors to stabilize the

shaker armature.

A specially designed angular plate is available for calibrating the 993B-7-M12 triaxial

accelerometer. This plate will excite all three axes simultaneously, resulting in 0.57 g per

axis. See section 6.0.

5.2.2 Power ON/OFF

Turns on the shaker for approximately 90 seconds. The unit will default to the previously

selected options. To defeat the auto shutoff feature and enable continuous operation, hold

down the FREQ button while turning the unit on. All three frequency LEDs will briefly

illuminate to indicate the shaker is in CONTINUOUS operating mode. The unit will now

operate until the ON/OFF button is pressed again. When the unit is turned off, it will revert

to the AUTO-OFF mode.

5.2.3 Frequency selection

The user has a choice of three frequencies. Momentarily press the FREQ button to select

the desired frequency as indicated on the respective LED. During frequency changes, the

output of the shaker is turned off momentarily. It is normal for the OOR indicator to

illuminate briefly after a new frequency is selected. See table 1 for additional information.

The ReferenceMate 2500 will always produce an amplitude of 1 g at the selected frequency.

•61.4 Hz is the most common frequency selected for machinery vibration and

analysis when working with imperial units (US). One g at 61.4 Hz is equal to 1

in/sec (ips) velocity.

•100 Hz is the preferred frequency for checking accelerometer performance against

calibration data. 100 Hz is the most common reference frequency used by

accelerometer manufacturers, thus allowing for a comparison with the original

calibration certificate.

•159.2 Hz is the most common frequency used when working in metric units where 1

g is equal to 9.81 m/sec2 acceleration, 9.81 mm/sec velocity and 9.8 μm

displacement.

5.2.4 RMS/PEAK

Select between RMS and PEAK by holding down the FREQ button. Figure 3 below

illustrates the relationship between PEAK and RMS.

RMS value = 0.707 x peak value

Peak value = 1.414 x RMS value

Peak to peak value = 2 x peak

value

Peak to peak value = 2.828 x RMS value

Figure 3: the relationship between peak, RMS, and peak-to-peak

5.2.5 BAT (low power) LED

The red BAT LED indicates remaining battery life is short and the batteries should be

replaced soon. (See section 4 for battery installation instructions). If the battery voltage

becomes too low, the unit will shut off and will not operate. The internal power supply is well

regulated and 1g acceleration will be maintained even though the battery voltage fluctuates.

Battery life is dependent on the type of batteries used, weight of the load and if the shaker is

being operated in the Peak or RMS mode. Table 3 shows approximate battery life

expectancy
