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
• 100.0 Hz to confirm accelerometer performance at the same reference frequency used by
most manufacturers
• 159.2 Hz for metric measurements, where 1 g is equal to 9.81 m/sec
2
and 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 REF2500 handheld shaker included in the REF2510 and REF2510R
kits, and the use of applicable accessories, both standard and optional.
