1Introduction
ABC-MEMS is the third generation of ABC Instrument’s smart vibration meter/datalogger. It
includes It includes a 3-axis MEMS accelerometer, an accurate date/time clock, a non-volatile 128 Mb
recording memory and wireless connectivity with fast USB and WiFi™ download. Depending on the
settings it can record vibration/velocity signals and/or RMS vibration/velocity levels for months. Its very
small size allows it to be attached to, or embedded within, the monitored equipment.
The ABC-Mems model is an evolution of the 1e model. It has the following new
features:
•Can measure, record and trigger on velocity signals, in addition to acceleration signals.
•Has WiFi™ reporting and email alarms.
•Includes an accelerometer with exceptional noise floor (20 times better noise floor than the
Vibration Mems -16g).
•Sampling rates up to 4 kHz.
•Improved anti-aliasing filter.
The ABC-Mems includes the following features:
•3-Axis integral MEMS accelerometer
•Measures and records:
oRaw acceleration or velocity signals
oAcceleration or velocity signal statistics
oVibration or velocity RMS levels
oInclinations
•All-digital design.
•Integrated oscilloscope function that can show the vibration or velocity signals in real time.
•Allows the observation of recorded data while the recording is ongoing.
•Works standalone, or USB or WiFi™ connected for setup and data transfer to PC.
•Long life internal rechargeable battery that recharges from USB.
•Self-calibrated using the earth’s gravity as a reference.
•Observes and records 100% of the acceleration signals (no missed samples).
•Editable individual custom ID for easier instrument management.
•Completely sealed weatherproof enclosure.
2Applications
•Building-health monitoring on construction sites.
•Long-term seismic monitoring.
•Long-term inclination monitoring.
•Long-term measurement and recording of acceleration signals, velocity signals, signal
statistics (peaks and average) and RMS levels.
•Continuous monitoring of machinery wear.
3Warnings
Avoid over-discharging the battery

User’s Manual
5
•Recharge the instrument immediately if the LED indicates a low-battery condition.
•Even if the instrument is Idle all or most of the time, recharge it fully at least once every 6
months.
Do not store or operate the instrument at temperatures exceeding the following limits
•-20 °C to 60 °C (-4 °F to 140 °F)
Do not mount on a metal plate. That would drastically weaken the WiFi™ signal.
4Getting Started
4.1 Software Installation
•On the PC that is used to setup the instrument, run Instrument_Manager_Installer.exe. This
installs the Instrument_Manager application, as well as its USB driver and documentation.
•On the PC that is used as a server, to collect data over the network, run
Instrument_Listener_Installer.exe. This installs the listener application that is used to respond
to instrument incoming connections, and create and fill the corresponding data files.
Note: The same PC can be used for both applications.
Note: Perform the software installation above BEFORE connecting the instrument to the PC for the
first time. The installer includes a USB driver, which is required for the PC to recognize the instrument.
4.2 Hardware Installation
1. Connect the instrument to an available USB port on the PC.
2. Verify that the PC properly detects the instrument and loads the driver. In case of doubt see
section Troubleshooting. Note that it can take some time for the PC to load the driver, the first
time the instrument is connected.
4.3 Initial Test and Configuration
1. Upon connection to the PC, the charge LED should immediately light-up yellow (charging) or
green (charged). Once the PC has loaded the driver the operating LED should blink once per
second.
2. Go into Start\All Programs\ABC_Instruments\Instrument_Manager and run
Instrument_Manager.exe. The front-panel described in Figure 9 appears, and the application
tries to connect to the instrument. If it fails to find the instrument it indicates No Device Found. If
this is the case see section Troubleshooting
3. Otherwise the application switches-on the ABC-MEMS and starts communicating with it.

User’s Manual

4. If the Time and Date in the upper right corner of the application window are not properly
adjusted the application asks if you want the instrument time to be synchronized to the PC
time. Only say YES if the PC time is correct.
5. In addition, the application detects if the time zone of the instrument is different from the time
zone of the PC. If it is, the application asks to set the instrument to the same time zone as the
PC.
Note: If (in rare cases) the instrument is not intended to be used in the same time zone as
that of the PC used to configure it, we suggest to temporarily change the PC’s time zone to the
time zone where the instrument will be recording, let the application set the instrument to the
PC’s time zone, and change the PC’s time zone back after that initial setting. Afterwards
if/whenever the application asks to change the instrument time zone back to the PC’s time
zone, simply choose to cancel the adjustment.
6. In the front-panel of the application you should see the acceleration or velocity signals display
in real-time.
5Instrument Functions and Description
The instrument connects to a PC on a USB port. The Instrument_Manager application is used to set its
operating parameters and download recorded data.

6Principle of Operation
6.1 Power Consumption
The ABC-Mems is always on. However, when not in operation it only measures time, which only takes
a tiny operating current. In that Idle state it can stay on for up to 6 months.When the meter is
actively measuring, its power consumption is mostly affected by two factors:
•The accelerometer sampling rate.
•Whether it is recording raw signals or statistics.
The meter can be configured to connect to a server at regular intervals. When that function is
enabled, the meter will activate its WiFi™ interface at the defined interval, and attempt to connect
via WiFi™ for up to 1 minute. During that time, the instrument’s power consumption will be increased. If
the connection fails the meter will fall back to its previous state (Sleep or Recording).
Note: WiFi™communications consume battery, so when leaving the meter unused for a long
time, it is important to disable the WiFi™periodic connection feature.
In order to minimize the power consumption due to WiFi™ reporting, choose a longer WiFi™
connection interval, for instance 1 hour. Make sure that the router is well within range of the instrument.
WiFi™ consumption is greatly increased when the WiFi™ signal is weak.
The Instrument_Manager application automatically calculates and displays the cumulative number of
days that the battery would last while recording, as a function of the instrument settings.
Note: That indication does not take into account any WiFi™ reporting.
In applications where the meter must record for longer periods of time, it can be connected to a
USB charger. For outdoor-use, a USB-output solar panel,
that will power the instrument indefinitely.
6.2 Battery Charging
The battery charges whenever the following conditions are met:
•The battery is not already fully charged.
•The instrument is connected to a PC’s USB port and the PC is not in standby, or
•The instrument is connected to a USB charger.
Note: In order to charge the instrument properly, use a USB charger that is either compliant with the
USB charging specification (most commercial dedicated USB chargers), or the Apple charging
specification (most Apple chargers that have a USB output). We do not recommend using the USB
outputs of cell-phone chargers, as many do not follow either standard.
While charging, the charge LED is orange. When fully charged, the LED changes to green.
The charge time from a completely discharged state varies with the amount of power the PC allows the
instrument to draw. Charge time is normally around 2H30. If the PC does not allow the fast charge
current, the charge time can increase up to 5 to 6 hours.

User’s Manual
8
Note: When connected to a PC, battery charging stops while the PC is in standby.
Note: It is OK to leave the instrument connected to a PC or USB charger all the time. The smart
charger inside the instrument will stop charging as soon as the battery reaches full-charge.
6.3 Modes of Operation
The meter has four modes of operation:
Mode
Operation
Power Consumption
Idle
Disconnected from USB and not actively
recording - Only keeps time.
Minimal: Only needs to be recharged
every 6 months.
Active
Connected to USB – Not recording –
Instrument is fully on and measuring
Instrument draws power from USB to
power itself, and if necessary recharge
its battery. Battery is not depleted.
Recording
or Auto-Rec
USB-connected or not - Fully on and
recording.
If USB-connected, power comes from
USB. If not, power comes from the
internal battery. Power consumption
depends on the instrument settings, and
can go from days to months.
Periodic
WiFi™
Connect
From any state, including Idle and
Recording, the instrument can periodically
wake up its WiFi™interface and attempt to
connect to a server. If the connection is not
established after 1 minute it falls back to its
original state until the next connection time.
If USB-connected, power comes from
USB. If not, power comes from the
battery. The Periodic Connect feature
consumes battery. This is especially the
case if the connection interval is set to
be short so it occurs often.

6.5 Acceleration Sensor and Signal Processing
6.5.1 Measurement
The 3-axis MEMS accelerometer inside the ABC-Mems accurately measures static (DC) and dynamic
(AC) acceleration signals with an adjustable sampling rate of up to 4 kHz.
Velocities are calculated in real-time from the acceleration sensor.
The accelerometer’s dynamic range is +-8g.
When measuring accelerations an adjustable-frequency high-pass filter can be added to the
measurement path. The high-pass filter is required to measure RMS vibration levels. Otherwise the
measured RMS levels would be biased by the DC component. On the other hand, inclination
measurements require the measurement of the DC component, so DO NOT use the high-pass filter for
inclinations.
When measuring velocities, a high-pass filter is automatically placed in the signal path. The cutoff
frequency is adjustable, and has an impact on velocity noise.
The instrument’s power consumption is proportional to the sampling rate, and dependent upon whether
the instrument is set to record raw signals or statistics.

User’s Manual
10
Figure 2 Signal Processing
Figure 2 shows the signal processing flow for one axis of the accelerometer.
The raw acceleration signal is sampled at an adjustable rate. The sampling rate can go up to 4 kHz.
The signal is then optionally high-pass filtered to remove the DC and low-frequency components. This
is usually required to capture RMS vibration levels. The cutoff of the high-pass filter is adjustable.
Alternately, the acceleration signal is digitally integrated to yield a velocity signal.
•In the Raw-Signal branch the signal (acceleration or velocity) is recorded at the sampling
frequency.
•In the Signal Statistics branch Min-Max-Avg processing captures the min, max and average of
the acceleration or velocity signal over an adjustable recording (log) interval. For each new
interval the statistics are cleared, then the statistics are updated during the course of the
interval, then at the end of the interval the statistics are recorded, and a new interval is started.
•In the RMS-Level branch the signal is squared to calculate the instantaneous power. The
instantaneous power is low-pass-filtered with an adjustable time constant to produce an
average. A short time constant provides an average that is capable of tracking fast transients,
while a longer time constant provides a smoother and less noisy average. A typical fast time
constant is around 100ms. While a typical long time constant is around 1s. Finally the square-
root of the power is taken to present RMS vibration or velocity levels. The RMS vibration levels
can be displayed in linear or dB scale.
•In the Level-Statistics branch Min-Max-Avg processing captures the min, max and average
vibration levels over an adjustable recording interval. For each new interval the statistics are
cleared, then the statistics are updated during the course of the interval, then at the end of the
interval the statistics are recorded, and a new interval is started. The RMS vibration levels can
be displayed in linear or dB scale.
Irrespective of the setting, the instrument always observes 100% of the acceleration samples.

6.5.3 Low-Frequency Limit
The low-frequency can optionally be limited by the digital high-pass filter. The cutoff frequency is
adjustable, and can be adjusted to extremely low frequencies thanks to the filter’s exceptionally high
resolution. Figure 5 shows the low-frequency response for a high-pass filter adjusted to 1 Hz, 5 Hz and
10 Hz, and operating at 4 kHz sampling frequency.

6.5.5 Sensor Dynamic Range
The sensor’s dynamic range extends from -8 g to +8 g. The precise dynamic range is dependent upon
the calibration and varies slightly from an individual instrument to the next.

User’s Manual
14
6.6 Calibration
The calibration uses the earth’s gravity as a 1g reference signal. The calibration procedure is
completely automated and can be performed at any time. It requires the user to set the instrument in
successive stable positions with its X, Y and Z axes aligned vertically while the instrument takes the
reference measurements.
At any time the calibration can be checked by using the static acceleration measurements. The
following procedure can be used to check the calibration:
1. Place the instrument in a position where the X axis is in the vertical position and axes Y and Z
are horizontal. Read the static acceleration (Static tab in Instrument_Manager). If the
calibration is correct the static acceleration along the X axis should be 1g. The static
acceleration along the Y and Z axes should be 0g.
2. Place the instrument in a position where the Y axis is in the vertical position and axes X and Z
are horizontal. Measure the static acceleration. If the calibration is correct the static
acceleration along the Y axis should be 1g. The static acceleration along the X and Z axes
should be 0g.
3. Place the instrument in a position where the Z axis is in the vertical position and axes X and Y
are horizontal. Measure the static acceleration. If the calibration is correct the static
acceleration along the Z axis should be 1g. The static acceleration along the X and Y axes
should be 0g.
6.7 Scale
The records in a scale that is internal to the instrument. All data is re-scaled for display as
selected by the user, whether it is g or m/s2for acceleration, or m/s for velocity, dB or linear. This way
the data can be displayed in any scale irrespective of the scale selected at the time of the recording.
6.8 Inclinations
The instrument’s inclination around the X and Y axes is not measured directly. It is calculated by the
Instrument_Manager application, from the components of the earth’s gravity along the three axes. So in
order to display inclinations, the instrument must be setup to record acceleration statistics, and at least
record the average accelerations along the X, Y and Z axes, with no high-pass filter.
After recording, the average accelerations along the X, Y and Z axes can be displayed by the
Instrument_Manager application as individual-axis accelerations, or as inclinations.
Using the three components of acceleration along the X, Y and Z axes, the inclinations around the X
and Y axes can be calculated. These are named:
•Tilt around the X axis: Theta
•Tilt around the Y axis: Phi
Theta and Phi are displayed in the Static tab, along with a graphical depiction of the instrument in real
time.
In addition to the inclination angles, the application calculates the norm of the acceleration. If the
instrument is stationary, and only subjected to slow changes in inclination, and is properly calibrated,
the norm of the acceleration should always be constant and equal to 1g.

User’s Manual
15
6.9 Manual Recording
A manual recording is started by pressing the Record button in the Setup tab of the
Instrument_Manager application.
Every time a recording is started, a new record is created in memory and filled until the recording is
stopped. That record is time-stamped, so the signals can be displayed with respect to absolute
date/time. Records are stored sequentially in the instrument’s memory. There is no limit to the number
of records that the memory can contain, only a limit to the total size of the data recorded. The
Instrument_Manager application displays the total memory recording time as a function of the various
setup parameters.
After (or while) recording, the records contained in memory can be downloaded from the instrument
and observed or exported. In case a recording is ongoing the last record is only displayed up to the
present time.
The recording is stopped automatically when the recording memory is full. This way a new record will
not overwrite an old one.
The recording memory is non-volatile, so there is no risk of losing the data that has already been
recorded, even in the case of a battery failure.
Note: It is perfectly legal to find empty records in memory. That occurs typically when a recording is
started and stopped quickly (for a time shorter than the log interval), before any data had time to be
written to memory. In that case only the time-stamp is written to memory.
An empty record can also occur when a recording was started but no data was selected to be
recorded.
To start a recording manually follow the steps below:
1. Select the type of signal (Acceleration or Velocity), and select the sampling frequency.
2. Select the type of data to record (raw signal, signal statistics or RMS levels). Select the axes
and/or statistics to record.
3. Select the log-interval. Note that the total recording time is automatically calculated and
displayed by the Instrument_Manager application, as a function of the log-interval and type of
data selected. The log-interval is adjustable in 125 ms increments, from 125 ms up to 2H.
4. If recording RMS levels, select the time constant used to smooth the measured sound levels
for L-min and L-max. Choose a time constant around 125 ms to be able to detect short
transients. Choose a time constant around 1s to provide cleaner more stable RMS levels. Or
adjust to another value, as required by the application.
5. When ready to start a recording immediately, simply press the Record button. Press Record
again to stop the recording.
6.10 AutoRec Recording
AutoRec allows the recording to start when the signal measured passes a preset limit. The recording
stops after the signal has been measured below the preset limit for at least equal the preset duration.

User’s Manual
16
AutoRec is mainly used to record raw signals. When recording raw signals, the memory consumption
grows very rapidly with time. So in order to monitor raw signals over a long time, only short segments
can be captured at a time.
When statistics are being monitored, the instrument has enough memory to be able to record non-stop
for weeks and months. So AutoRec is not really necessary.
AutoRec will capture a certain number of pre-trig samples (256 samples).
For instance AutoRec can be setup to:
•Start recording a raw acceleration signal whenever the acceleration passes 0.2g.
•Stop recording whenever the acceleration signal is < 0.2g for at least 10s.
AutoRec setup always requires two parameters:
•A threshold to start the recording (Acceleration or Velocity). The recording will start as soon as
the signal passes the threshold.
•A minimum duration to stop the recording. The recording will stop after the preset duration has
elapsed with the signal staying below the threshold.
The threshold is set in 𝑚/𝑠2for accelerations, and in 𝑚/𝑠for velocities.
The threshold applies to the raw signal if the instrument is set to record raw signal or signal statistics. In
that case, the threshold value 𝑇defines a positive threshold +𝑇and a negative threshold −𝑇. The
recording starts whenever the raw signal goes outside of the interval [−𝑇, +𝑇]. When measuring
acceleration signals without high-pass filter, the threshold is applied relative to the static acceleration at
the time when AutoRec is started. This way it is also possible to trigger a recording when the tilt of the
instrument changes by a predefined amount.
The threshold applies to the RMS level if the instrument is set to record RMS levels. In that case the
threshold value defines a positive threshold +𝑇. The recording starts whenever the RMS value goes
outside of the interval [0, +𝑇]
In order to trigger the recording, the signal must pass the threshold on any individual axis. For instance,
if the instrument is set to record raw velocity signals the trigger value 𝑉represents a cube around the
origin (0,0,0), with a side-length of 2𝑉.
7 WiFi™ Connectivity
The ABC Mems supports a mode of operation where it periodically connects to a server (a Windows
PC running the Instrument_Listener application) through WiFi™. This feature is designed to let the
instrument record autonomously, periodically report the levels or signals recorded since the last
connection, and optionally send emails with RMS-level or low-battery alerts. When set, this feature will
work, even if the instrument is reset, or if it loses and regains battery power (for instance if the
instrument is reconnected to a charger after the battery has been completely drained).
This PC-server being connected-to does not have to be in the vicinity of the instrument. It can be a
continent apart, as long as it is reachable through the internet, and all firewalls have been set to allow
the connection.
The instrument connects to a WiFi™ Router or Access Point that is in its vicinity. From there, it will find
the server to connect to, either by its IP address, or by its domain name.

User’s Manual
17
7.1 WiFi™ Reporting
Note: When using the instrument with WiFi™ connectivity, do not start a recording manually, or via
the timer. The instrument will be completely controlled by the server, including starting the recording,
erasing memory if required, and resetting the time.
When using the WiFi™feature, the instrument will try to connect to a known server at regular intervals,
or immediately in case of alarm.
Whenever it connects the instrument will talk to a special Instrument_Listener application running on
the server. That application will do the following:
•If the instrument is currently recording:
oUpload the latest recorded data from the instrument and updates a growing file with
that data (create the file if it was not already created).
•If the instrument is not currently recording (for instance if the recording was stopped earlier
because the memory was full):
oUpload the latest recorded data from the instrument (if any) and update the recording
file.
oAdjust the instrument time (does not adjust the time zone of the instrument, just
precisely readjust the Universal-Time-Code running in the instrument).
oDelete all data in the instrument’s memory (all that data has already been safely
stored in the recording file on the server).
oStart a new recording, or Start the AutoRec mode.
7.2 Email Alarms
In addition to trying to connect to the server at regular intervals, the instrument will try to connect
immediately to the email server in case of alarm. The alarm function does not require the use of a
server or Listener application. The instrument will connect directly to an email server, such as a gmail
account.
In order to be able to send an alarm email, the instrument must have the following setup:
•A WiFi™ Router or Access Point must be in the instrument’s vicinity, and the instrument must
have been configured with that router’s connection parameters. That is part of the WiFi Setup
of the instrument.
•The instrument must have been configured with an outgoing email account and connection
parameters. That is part of the Email Setup of the instrument.
Two alarms can be enabled:
•A signal or level past a preset threshold. The threshold works exactly the same as the
threshold used for AutoRec, but a different threshold can be specified. When the same
threshold is used, the instrument will both:
oStart a recording of the raw signal.

oSend an alert email.
•The battery is close to being depleted.
