The OM-SQ2040 Series combines a

higher channel count with the same

high performance, comprehensive

features and universal inputs as the

OM-SQ2020 in a neat compact and

portable instrument. Using multiple

24-bit analog to digital convertors, twin

processors and removable memory

options provide great flexibility to

handle a wide range of complex and

demanding multi-channel applications.

The OM-SQ2040 series are the ideal

data loggers for industrial, scientific

research and quality assurance

applications. The OM-SQ2040

provides stand-alone data

acquisition, advanced networked

solutions and data analysis straight

out-of-the-box.

Input Connections

The OM-SQ2040-2F16 data logger

has two analog to digital converters

(A/D’s) which increases logging

flexibility over the OM-2020-1F8

model. The first corresponds to

inputs on blocks A, B, C and D and

the second corresponds to inputs

on blocks G, H, J and K. 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-SQ2040-4F16 data logger

has four analog to digital converters

(A/D’s) which increases logging

flexibility over the other OM-SQ2020

and OM-SQ2040 models. The first

corresponds to inputs on blocks A

and B, the second corresponds to

inputs on blocks C and D, the third

corresponds to inputs on blocks G

and H and the fourth corresponds

to inputs on blocks J and K. 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-SQ2040 series uses multiple

analog to digital converters that

enables true concurrent sampling

and logging. This allows the user to

configure up to 4 channels to log at a

rate of 100 Hz while retaining different

sample speeds on other channels.

This makes the OM-SQ2040 ideal

for measuring dynamic parameters

that change at different rates such as

temperature and pressure.

Communications Ethernet,

Wi-Fi (on the OM-SQ2040-2F16-WIFI

and OM-SQ2040-4F16-WIFI) USB

and RS-232 serial ports are

built-in. This allows quick connection

to either a PC based TCP/IP network,

a wireless to PC connection or to a

modem for remote data downloading.

This flexibility enables global data access and

OM-SQ2040 series into complex

and critical applications.

Multiple Configurations Stored

in the 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 switch between logger

configurations without the need for a PC.

Comprehensive Software Configuration

The OM-SQ-SOFT software (supplied with the

OM-SQ2040 series data loggers) allows logger

configuration, data download and data export while

giving the user full control over the OM-SQ2040.

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-SQ2040 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

astatistical summary of your data, set high and low

alarm thresholds and, using the calculation function,

you can create new virtual channels from existing

channels.

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.
