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.

Calibrating Triaxial Sensors
Calibrating triaxial sensors is done in the same way as a uniaxial sensor, but the measurements
are taken three times on three dierent axes.
Recommended method: Plug the sensor into AT2040's 8-pin DIN connector to change
between axes using the calibrator's electronics and internal relays. Using this method, the
operator only needs to change the positioning of the sensor and not the cable.
Alternate method: If the operator would prefer to use BNC breakouts instead of the internal
electronics, AT2040 supports that as well.
To calibrate a triaxial accelerometer:
1. Mount and connect the accelerometer (Figure 36).
2. Choose Test from the main menu.
3. Choose the appropriate channel.
4. Select the sensor model and sensitivity.
5. Take the rst set of readings for the X-axis.
6. Rotate the sensor 90-degrees (Figure 36) and select the next triaxial channel in the
AT2040 menu screen.
NOTE: If using BNC breakouts, the operator must stay on Triax Channel A and change the
connector manually instead.
4. Take second set of readings
5. Repeat step 3.
6. Take third set of readings.

Choosing Between a Dynamic and Linear Test
Figure 40. Proximity probe driver connected to AT2040
AT2040 provides the needed −24 volts to power output for proximity probe drivers. It also reads
in both AC and DC values. This allows the operator to conduct probe/driver tests without any
add-on power supplies or external volt meters.
Proximity probes can be checked by conducting a dynamic or linear test:
• A dynamic (AC) test is done by reading in the AC voltage during vibration and performing a
sensitivity test at a xed-gap voltage.
• In a linear (DC) test, the gap voltage is adjusted over a linear range and the Proximity
Probe Test Template spreadsheet included on the USB drive is completed showing the
incremental scale value. A linear test can be performed with or without vibration from the
AT2040.
It is recommended to perform a linear test rather than a dynamic test. A linear test will show the
ISF over the entire range of a probe/driver, whereas a dynamic test shows increasing amplitude
(sine wave size) at a xed-gap voltage.
Connecting the Proximity Probe Driver
1. Connect the driver to the Proximity Probe Driver Input (labeled "1" in Figure 39), see
also Figure 40:
a. Connect Signal to "Sig".
b. Connect Common to "Com".
c. Connect −24 volts to "−V".
Figure 39. Proximity probe driver input
NOTE: The driver receives power from the AT2040.
NOTE: The AT2040 reads in both AC and DC voltage from the driver.

Table 8. ISF data auto-populates based on test data
Conducting a Linear Test
During a linear (DC) test, the probe is set at the 0 position and adjusted using the micrometer
from 0–10–20–30, and so on, covering the entire linear range. Linear tests are done in manual
mode and the amplitude is not adjusted.
To conduct a linear test:
1. Assemble and install the proximity probe kit, per instructions in Installing the Proximity
Probe Kit on page 30.
2. Connect the proximity probe driver, per instructions in Connecting the Proximity Probe
Driver on page 32.
3. Choose Test from the main menu.
4. Select Prox as the sensor type, then select the proximity probe manufacturer and model.
5. Select the Manual button on the sensor prole screen.
6. Adjust the probe to 10 mils from the target.
7. Using the Proximity Probe Test Template spreadsheet on the included USB drive (see
example spreadsheet on next page), create a test over the span of 10 mil test increments.
The Proximity Probe Template in Excel format is provided to assist you with these
calculations.
8. Start by lling in "Test 1" data in the Excel spreadsheet at cell 6C (yellow cell in Table 7).
9. Rotate the spindle to 20 mils and record the voltage in cell 7C (green cell in Table 7).
10. Continue in 10 mil-increments until the upper-end of the linear scale, completing column C
in the Excel spreadsheet ("Test 1" column in Table 7).
11. Calculate the voltage change by using the spreadsheet to ll in test points H6–H14
("ISF Test 1 mV/mil" column in Table 8)
NOTE: It is always a good idea to perform the test a second time, completing column D in the
Excel spreadsheet ("Test 2" column in Table 7).
12. Log and analyze data by looking for the linear relation between travel and voltage.
13. Locate the ISF and measurement tolerance printed on the proximitor and housing. For
example, 200 mV over 10 mil-increments results in 2 volt (200 millivolt) changes.
14. Compare the ISF on the driver housing to the results of your test ("ISF Test 1" or
"ISF Test 2" columns in Table 8).
NOTE: Example test data is provided in the two "EXAMPLE" columns in Tables 8 and 9.

8. Assemble and install the proximity probe kit, per instructions in Installing the Proximity
Probe Kit on page 30.
9. Connect the proximity probe driver, per instructions in Connecting the Proximity Probe
Driver on page 32.
10. Locate the gap voltage, shown as "GAP V", on the sensor prole screen (Figure 41). The
gap voltage is the DC voltage measurement from the probe/driver and is shown as a
negative value.
Figure 41. Sensor profile screen for the proximity probe
11. Rotate the micrometer clockwise to push the probe all the way down until it contacts the
steel target.
NOTE: The GAP V (DC voltage value) on your calibrator should read less than −1 volt.
12. Rotate the micrometer counterclockwise to retract the probe tip until the GAP V reads the
previously calculated value. In our example, we determined a gap voltage of −9 volts.
13. Select the Manual button or Automatic button on the sensor prole screen (Figure 41).
a. In automatic mode, the AT2040 will conduct the test without the need for further
adjustments.
b. In manual mode, adjust the speed to the same RPM as the driveshaft you would like
to simulate. Then, increase the amplitude over a range of 1 to 10 mils.
Conducting a Dynamic Test
During a dynamic (AC) test, the AT2040 takes on the role of simulating a rotating shaft. The
4140 steel target will produce the same vibration signals as a steel shaft. In this test, the
operator will set the probe gap voltage and adjust the amplitude. With the AT2040 this can be
performed in either manual or automatic mode.
1. Choose Test from the main menu.
2. Select Prox as the sensor type.
3. Select the proximity probe manufacturer and model.
4. Locate the recommended gap setting on the proximity probe driver spec sheet:
Example Driver Spec Sheet (for 200 mV/mil probe/driver combination)
Recommended Gap Setting 1.27mm (50 mils)
5. Determine the exact voltage at the center of the linear range, using the recommended gap
setting and the following formula: [6]
(recomm. gap setting in mils*0.2)-1 = volts DC [ (50*0.2)-1 = −9 volts ]
6. If a recommended gap setting is not available, locate the linear range listed on the
driver spec sheet (most probe and driver combinations are 200 mV/mil, where every
10 mils is equal to 2 volts):
Example Driver Spec Sheet (for a 200 mV/mil probe/driver combination)
Linear Range 2 mm (80 mils). Linear range begins at approximately
0.25 mm (10 mils) from the target and is from 0.25 to
2.3 mm (10 to 90 mils) (approximately −1 to −17 Vdc).
7. Determine the exact voltage at the center of the linear range, using the following
formula: [6]
((range/2+10)*0.2)-1 = volts DC [ ((80/2+10)*0.2)-1 = −9 volts ]
[6] Both formulas will equate the voltage at the center of the linear range. In both examples
shown above, our result is −9 volts DC.
NOTE: Always remember that linear range does not begin until the probe is 10 mils from the
target.
