Using Mathematical Functions
The OM-SQ2020 Series of hand
held data loggers combines high
performance, powerful features and
universal inputs in a compact and
easy-to-use instrument.
Using high accuracy 24-bit analog
to digital converters, removable
memory and Ethernet networking
(on the OM-SQ2020-2F8), the
OM-SQ2020 Series is the ideal
data logger for industrial, scientific
research and quality assurance
applications. Together with our
comprehensive suite of software,
the OM-SQ2020 provides
standalone data acquisition,
real-time metering and data analysis
straight out-of-the-box.

Input Connections
The OM-SQ2020-1F8 data logger
has a single analog to digital
converter (A/D) which corresponds
to inputs on blocks A through to D.
Each connection block will accept
up to 2 differential inputs or up to
4 single ended inputs (it is not
possible to mix single- ended and
differential inputs on a block).
The OM-SQ2020-2F8 data logger
has two analog to digital converters
(A/D’s) which increases logging
flexibility over the OM-SQ2020-1F8
model. The first corresponds to
inputs on blocks A and B and the
second corresponds to inputs on
blocks C and D. Each connection
block will accept up to 2 differential
inputs or up to 4 single-ended inputs
(it is not possible to mix single ended
and differential inputs on a block).
Concurrent Sampling
The OM-SQ2020 Series uses
multiple analog to digital converters
that enables true concurrent sampling
and logging.
This allows the user to configure a
channel to log at a rate of 100 Hz
(20 Hz on OM-SQ2020-1F8) while
retaining different sample speeds on
other channels. This makes the
OM-SQ2020 Series ideal for
measuring dynamic parameters that
change at different rates such as
temperature and pressure.
Communications
Ethernet (on OM-SQ2020-2F8),
Wi-Fi (on OM-SQ2020-2F8-WIFI),
USB and RS-232 serial ports
are built-in. This allows simple
connection to either a PC based
TCP/IP network, a wireless to PC
connection or to a GSM modem
for remote data downloading. This
flexibility enables global data access
and retrieval as well as complete
system integration of the
OM-SQ2020 series into complex
and critical applications.

Multiple Configurations
Stored in the Data Logger
Up to six logger configurations (channel type, names,
logging speeds, triggers etc), together with the current
configuration, can be held in the logger’s internal
memory. Additional configuration settings can also
be loaded from the external MMC/SD memory card.
This allows the operator to quickly and easily
between logger configurations
without the need for
switch
a PC.
Comprehensive Software Configuration
The OM-SQ-SOFT software (supplied with the
OM-SQ2020 series data loggers) allows logger
configuration, data download and data export while
giving the user full control over the OM-SQ2020.
The optional OM-SQ-SOFT-PLUS software gives
the user access to many advanced data analysis
and data archiving/transfer features. The optional
OM-SQ-SOFT-PLUS software lets you quickly and
easily analyze the data from your OM-SQ2020 data
logger in a familiar explorer style interface. Data can
be displayed with 2 different auto scaling Y-axis. This
is particularly useful when displaying widely varying
data from different sensors on one graph.
You can also zoom in on areas of interest, use a
cursor to pick out exact values, times and dates,
get a statistical summary of your data, set high and
low alarm thresholds and, using the calculation
function, you can create new virtual channels from
existing channels.
Standard Ranges for dc Voltage
Each voltage channel can be any of the voltage
ranges below. Mixed differential and single ended
configurations are permitted. Please refer to our
technical notes for the permitted combinations of inputs.
High Voltage
Voltage Range Voltage Range Input Ranges*
-0.075 to 0.075V -3.0 to 3.0V 4.0 to 20.0V
-0.15 to 015V -6.0 to 6.0V 4.0 to 40.0V

-0.6 to 0.6V -6.0 to 25.0V
-0.6 to 1.6V
-0.6 to 2.4V
* Max of 2 may be selected
The OM-SQ-SOFT-PLUS software also incorporates
a report generation facility, which allows you to create
custom report templates consisting of a title page
with descriptive text, headers and footers, graphs,
tabular list of data, statistics and data logger setup
information. Templates can be setup with any of these
combinations and saves time when preparing similar
presentations of data.
OM-SQ-SOFT Windows software

displays data in graphical or tabular format.
