AGATE TECHNOLOGY AT2040
Introduction
This manual is intended to inform the operating user on product specications, setup,
troubleshooting, and operation procedures for the AT2040. The AT2040 is designed as a
rugged, completely self-contained, battery-powered, vibration sensor test set. The AT2040 is
meant for use in the eld or laboratory, for the verication of control room working conditions, or
to verify the performance of vibration transducers.
Product Technical Support
For technical support for the AT2040, email us at [e-mail] or call us
at 951-719-1032. Training webinars are also available; contact technical support for more
information.

Safety information
Please keep this manual in a safe location for reference.
WARNINGS
• AT2040 is designed for vertical use. Operating in
the horizontal position is possible as the AT2040
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 have 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 damage to
the AT2040.

Primary functions
1. Shake or excite a transducer under test
In shake mode, the AT2040 can be used as a variable frequency and variable amplitude
shaker. In this mode, the frequency and amplitude are set manually by the user while the
computer provides high-accuracy measurement signals.
2. 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 AT2040 can automatically
determine the test transducer's sensitivity to a high level of accuracy.
3. Produce a NIST-traceable calibration certicate
Once the sensitivity has been calculated and saved across the test transducer’s frequency
range, the AT2040 will produce a NIST-traceable certicate and graph in PDF format. This
certicate is stored in the computer’s memory and may be recalled and exported at any
time to a USB memory drive.
4. Simulate a transducer using a precision signal generator (function generator)
The AT2040 is capable of producing signals over a wide amplitude and frequency using
its built-in ampliers 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.

AGATE TECHNOLOGY AT2040
Battery operation
The AT2040 is powered by one 6 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 plug-ins, payload weight, along with
shaker driving force.
In low power conditions, the AT2040 uses
approximately 0.4 amps of power making it
possible to achieve 13 hours of battery power.
However, the AT2040 will shut down premature
to full discharge preventing damage and
ensuring long-term battery life.
During long periods of high power
consumption, the AT2040 may only last up
to one hour.
A battery light indicator is located 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. See the included voltage
chart (Table 4).
The AT2040 may be operated with the power
plugged in. The AC charger will supply battery
charge when plugged in; however, the charge
rate will be greatly increased when the AT2040
is powered o.
NOTES:
• For best results use the AT2040 when the battery is fully charged.
• Automatic power management will automatically turn o 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.
