Knowledgeable staff and remote support - through advice and assistance. Website documentation confusing

The products were arrived soon. I surprised. But one of the four H3-HV I purchased did not include a USB cable. So minus 1.

I find that LabJack integrates well with Microsoft Visual Studio and it performs well in the developed app. Great measurement tool..!

I used both LabJack T7 & U6 with each of -7 PCS of CB37, - 2 * MUX80 -2 EI1034 Temperature Probe -2 EI1050 Digital Temperature / Humidity probe - 4 DB37 cable to measuring 145 position temperature 80 probe for K Type thermocouple 65 semiconductor type LM35dz in my Ph.D. project I found it so useful except 1- the software cannot support to read more than 14 probe in easily way 2- using external probe as a reference junction for more accurate to measuring temperature by employing other probes because the heat source from the body of each U6 or T7 make a small deviation when depending to the internal reference probe and I hope to avoid this problem I am happy to use LabJack product With my respect Dr.Ali D.

Labjack U3 user. Nice product, mature, available for a long time, performs as promised. Definitely a good choice for PC-based data acquisition. 4 stars instead of 5 because the documentation could be better structured / more polished. Examples: * Datasheet: no simple overview of the no of channels / channel types, a lot of scrolling through sections 2.6.x, 2.7.x and appendix just to have an overview of the no of channels + associated specs. * Chapter 4: function calls are listed, but take e.g. 4.2.3 ePut -> accepts parameters -> takes some browsing to find out this can be used for e.g. quickSettling -> more browsing to find explanation in 2.6 for quickSettling In the end all information _is_ available. But some short tutorial, or more documented example code right near the description might help.

Thanks for the feedback, positive and negative. LabJack's core focus in the data acquisition marketplace is providing the best computer based DAQs, so we love hearing what you think is great, and need to hear what you think has room for improvement. Your identification of areas of the U3 Datasheet that could use improvement is fair, and suggests that you have been immersed in the U3 at some point. For anyone reading this in the future, our primary tip for programmers new to the U3 and UD library, would be to focus on Section 4.3 (pseudocode) as the first place to look for information about the linkage between the U3 device and the UD library. We will make a to-do to look for areas of the site where we can further emphasize the importance of Section 4.3. Note that with our newer devices (T-series), improvements to the low-level protocol, high-level LJM library and hardware datasheet, all combine to improve this experience.

Software should be more intuitive.

The good: hardware is solid. T7-pro resolution is appreciated. Kipling and LJM are better than expected. Running quadrature encoders is appreciated. Smooth handshake with Visual Studio. The could-be-better: Actual instrumentation amps would be good for strain gages. Still haven't found a list of all the extended function indexes and what they do. Still a little confused how to set up Clock0 to run at a slower frequency.

I like specs, size, and price. My applications are not allowed to operate U3-HV with suggested third-party software. I do not have the skills to write my program. In my view, many customers will be heapy to operate LabJck products with the most common software, LabView or DasyLab.
