The OM-SQ2040 Series combines a higher channel count with the samehigh performance, comprehensive features and universal inputs as theOM-SQ2020 in a neat compact and portable instrument.Using multiple 24-bit analog to digital convertors, twin processors andremovable memory options provide great flexibility to handle a wide rangeof complex and demanding multichannel applications.

The OM-SQ2040 series are the ideal data loggers for industrial,scientific research and quality assurance applications.The OM-SQ2040 provides standalone data acquisition, advancednetworked 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-2020-1F8model. The first corresponds to inputs on blocks A, B, C and D andthe second corresponds to inputs on blocks G, H, J and K.Each connection block will accept up to 2 differential inputs or upto 4 single-ended inputs (it is not possible to mix single ended anddifferential 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-SQ2020and OM-SQ2040 models. The first corresponds to inputs on blocks Aand B, the second corresponds to inputs on blocks C and D, the thirdcorresponds to inputs on blocks G and H and the fourth correspondsto inputs on blocks J and K. Each connection block will acceptup to 2 differential inputs or up to 4 single— ended inputs (it is notpossible to mix single-ended and differential inputs on a block).

Concurrent Sampling:
The OM-SQ2040 series uses |multiple analog to digital convertersthat enables true concurrent sampling and logging. This allows the user toconfigure up to 4 channels to log at a rate of 100 Hz while retaining differentsample speeds on other channels. This makes the OM-SQ2040 ideal formeasuring dynamic parameters that change at different rates such astemperature and pressure.

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 retrieval as well ascomplete system integration of the OM-SQ2040 series into complexand critical applications.

Multiple Configurations Stored in the Logger:
Up to six logger configurations (channel type,names, logging speeds, triggers, etc.), togetherwith the current configuration, can be held in thelogger’s internal memory. Additional configurationsettings can also be loaded from the externalMMC/SD memory card. This allows the operator to quickly and easilyswitch between logger configurations withoutthe need for a PC.

Comprehensive Software Configuration
The OM-SQ-SOFT software (supplied with the OM-SQ2040 series data loggers) allows loggerconfiguration, data download and data export whilegiving the user full control over the OM-SQ2040.The optional OM-SQ-SOFT-PLUS software gives theuser access to many advanced data analysis and dataarchiving/transfer features. The optional OM-SQ-SOFT-PLUS software lets youquickly and easily analyze the data from yourOM-SQ2040 data logger in a familiar Explorer styleinterface. Data can be displayed with 2 different autoscaling Y-axis. This is particularly useful whendisplaying widely varying data from different sensors on one graph.You can also zoom in on areas of interest, use acursor to pick out exact values, times and dates, getastatistical summary of your data, set high and lowalarm thresholds and, using the calculation function,you can create new virtual channels from existingchannels.

The OM-SQ-SOFT-PLUS software also incorporates areport generation facility, which allows you to createcustom report templates consisting of a title page withdescriptive text, headers and footers, graphs, tabularlist of data, statistics and data logger setupinformation. Templates can be setup with any of thesecombinations and saves time when preparing similarpresentations of data.
