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/sec2

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 calibrati

on of the shaker’s

internal accelerometer.

3.0 Applicable models

The manual covers the model REF2500 handheld shaker included in the REF2510 and
