RSS FeedsData Logger > Lascar Recently, there’s been some confusion when it comes to calibration and EL series temperature data loggers. The fact that we offer a NIST traceable calibration certificate (sold separately) has led some to believe that a certificate must be purchased in order for the logger to be calibrated. On the contrary, EL Read More

An Overview of the All-New GL7000
Data Logger > Graphtec > GL7000 The GL7000 is a modular data acquisition system, configurable for a wide array of industrial applications. The unit is well constructed and has a solid feel. The base unit (without modules) measures 7.60”W x 5.55”H x 6.30”D and weighs in at approximately 4.9 pounds. Expansion modules (at least Read More
Learn How to Connect and Calibrate Thermocouples Using DI-8B47 Series Amplifiers
Data Acquisition > Thermocouple Check out out updated application note, covering the connection and calibration of thermocouples using DI-8B47 series signal conditioners. You’ll find step-by-step instructions on properly connecting thermocouples to your DI-718B, DI-718Bx or DI-788 series instrument. In addition, we’ll show you how to scale WinDaq to display engineering units (C or F) using the new ‘Engineering Unit Read More
An Overview of the PC-based APS Software for Graphtec GL Series Instruments
Data Logger > Graphtec The APS PC-based software for Graphtec Data Loggers gives you access to all of the features on the front panel of the instrument, and more. When connected to your PC via the USB or Ethernet interface, the APS software allows you to view real-time data, enable and configure channels, set alarms and generate Read More
How To Eliminate Noise in Data Logger and Data Acquisition Measurements
Data Acquisition > Products or Data Logger > Products (Note: This is a consolidated version of a six-part series on signal noise reduction in data logger and data acquisition systems.) This happens almost daily: A customer contacts our support group to complain of noise on his measurement. Almost invariably a comparison is made between the Read More
How To Eliminate Noise in Data Logger and Data Acquisition Measurements (Part 6 of 6)
Data Acquisition > Products or Data Logger > Products (Note: A consolidated version of this topic that contains all six part can be found here) Common Mode Voltages and Non-isolated Instruments You’ve arrived at part six of this series because you have noise on one or more acquired analog channels. Using procedures described in Part Read More
How To Eliminate Noise in Data Logging and Data Acquisition Measurements (Part 5 of 6)
Data Acquisition > Products or Data Logger > Products (Note: A consolidated version of this topic that contains all six part can be found here) Proper Shielding Techniques We’ve established that isolation amplifiers do not perform well in the presence of large, high frequency common-mode voltages. Now we’ll focus on eliminating high level, high frequency Read More
How To Eliminate Noise in Data Logging and Data Acquisition Measurements (Part 4 of 6)
Data Acquisition > Products or Data Logger > Products (Note: A consolidated version of this topic that contains all six part can be found here) Common Mode Rejection Ration (CMRR) We’ve touched on common mode voltage and how its magnitude and frequency can degrade the performance of an isolation amplifier. Now we’ll discuss the differential Read More
How To Eliminate Noise in Data Logger and Data Acquisition Measurements (Part 3 of 6)
Data Acquisition > Products or Data Logger > Products (Note: A consolidated version of this topic that contains all six part can be found here) Effects of Common Mode Voltage Frequency We’ve covered evaluating noise magnitude to see if noise elimination is worth the time and effort, and a procedure to test the instrument for Read More
How To Eliminate Noise in Data Logger and Data Acquisition Measurements (Part 2 of 6)
Data Acquisition > Products or Data Logger > Products (Note: A consolidated version of this topic that contains all six part can be found here) Common Mode Voltages and Isolated Instruments In the premier edition of this series I talked about how you should initially approach noise elimination. The first step is to ensure that Read More
