AGATE TECHNOLOGY AT-2040 OPERATOR MANUAL
Introduction:
This manual is intended to inform the operating user on product specifications, setup, troubleshooting,
and operation procedures on the AT-2040. The AT-2040 is designed as a rugged, completely self-
contained, battery powered, vibration sensor test set. The AT-2040 is meant for use in the field or
laboratory for the verification of control room working conditions or to verify the performance of
vibration transducers.
The AT-2040 consists of an internal charger, battery, main power amplifier, electrodynamic shaker, NIST
traceable reference, internal computer, signal generation board, and LCD screen display.
Block Diagram
Charger: Internal charger which operates between 110v and 220v for worldwide power
support.
Battery: 5 Amp Hour, Sealed, Lead Acid battery. FAA transport approved.
Power Amplifier: Takes the input signal from the Signal Generator and is used to drive the
electrodynamic shaker.

Electrodynamic Shaker: Produces 4.5 lbf pk of sine force and is made with carbon fiber
composite and isolated linear bearings. This provides low distortion when shaking the
transducer load.
Reference Accelerometer: NIST traceable calibration standard accelerometer with ¼-28
tapped mounting hole.
Computer: 1 GHz Cortex-A8 processor, 512 MB DDR3 RAM, 20GB of storage memory
included, with USB and network connectivity.
Signal Generation Board: Consists of multiple amplifiers and channels selectable by internal
relays. This is categorized into three different applications.
a. The Power Amplifier Output: To control the vibration of the electrodynamic
shaker at the amplitude and frequency set by the user.
b. Input: To read in sensitivity of multiple transducer types.
c. Signal Generator: To output a wide range of simulated voltage and current
measurements.
LCD Screen: Color 4.3 inch LCD 480x272 resolution display with resistive touch screen.
Primary Functions of the AT-2040:
oTo shake or excite a transducer under test.
In shake mode, AT-2040 can be used as a variable frequency, variable amplitude shaker.
In this mode, the frequency and amplitude are set manually by the user, while the
computer provides high accuracy measurement signals.
oTo calculate transducer sensitivity.
By comparing signals sent to the reference accelerometer by the signal generation
board and the signals returned by the transducer under test, the AT-2040 can
automatically determine test transducers sensitivity to a high level of accuracy.
oTo produce a NIST traceable calibration certificate.
Once the sensitivity has been calculated and saved across the test transducer’s
frequency range, the AT-2040 will produce a NIST traceable certificate and graph in PDF
format. This certificate is stored into the computer’s 4GB memory, or recalled and
exported anytime to USB.

oTo simulate a transducer using a precision signal generator (function generator).
The AT-2040 can produce signals over a wide amplitude and frequency using its built-in
amplifiers to simulate a variety of charge and voltage signals. This allows the user to
simulate a working transducer and is the ideal tool for electronics testing,
troubleshooting, or calibrating condition monitoring systems.
Warnings on Shaker Operation
AT-2040 is designed for vertical use. Operating in the horizontal position is possible as the
shaker element has linear bearings for support, but the load should not exceed 400 Grams.
This instrument may shake violently at high amplitude and low frequency. Always make sure to
keep the unit secure and operate on a stable surface.
When amplitude or frequency has exceeded their acceptable ranges, the unit will issue a
warning or shut down depending on the operating conditions.
Even when closed, this instrument is not waterproof. Never use near water.
Failure to hold the accelerometer with the short handle wrench when attaching and removing
transducers can cause permanent shaker damage.
Note about battery operation:
AT-2040 is powered by one 5-amp hour, sealed lead acid, rechargeable battery as its primary power
source. This battery is designed to be continuously charged at a trickle rate once the battery reaches
100%. Battery life will depend on USB plugins, payload weight, along with shaker driving force. In low
power conditions, AT-2040 uses approximately 0.4 amps of power making it possible to achieve 13
hours of battery power. However, the unit will shut down premature to full discharge preventing
damage and ensuring long term battery life. During long periods of high power consumption, AT-2040
may only last up to one hour. A battery light indicator is in the top menu bar and turns from green to
red as the battery becomes low on energy. Next to the battery bar, is an approximate percentage of
battery remaining based on the following voltage chart:

The portable shaker unit may be operated with the power plugged in. The AC charger will supply battery
charge when plugged in, however charge rate will be greatly increased when the unit is powered off.
For best results use the shaker when batteries are fully charged
Automatic power management will automatically turn off before full battery discharge. This is a
protective measure to ensure longer battery operating life.
If deep discharge occurs, the battery charger is set to recharge over two or more days. This is
normal operation to prevent battery damage.
