"Labjack T7 delivred from USA to Norway"

Ordered Labjack T7 online from USA. Goods were received in Norway 3 days later. No problems. Know the equipment from previous projects. Will be used in automated PCBA test stations. All good.

"I like their technical support"

I like their technical support, I can just chat with them during the available chat time and they will respond to you immediately.

"My package was lost in shipping"

My package was lost in shipping. They sent me a new shipment. Greeat customer service. So now if it shows up, I'll just send it back with a premade label. That is great I can keep moving on my tight time line.

"I have not idea how many email…"

I have not idea how many email support@LabJack receives every day, but all that I know is that they always reply within few minutes.

"We have been a customer of Labjack for…"

We have been a customer of Labjack for number of years now. Our startup company owns 3 T7 pros in addition to numerous add ons (LJTicks), Mux80 etc.

In my opinion LabJack’s customer support is top notch.

As with the latest purchase once again LabJack was prompt and as usual the service was very professional.

"Excellent support"

I used the T4. It was quick to set up for my project involving a strain gauge. When I needed assistance, Oren and Soloman were prompt to respond and only too supportive. Thank you both!

"The LJtick-R device is not designed to measure small resistance"

The LJtick-R device doesn't give stable enough data for my application (measuring R around 25 ohms). I received a call from tech support that confirmed the device will not work well to measure such lo resistance. So I built my own interface for the measurement, which is working better.

"The T8 is not ready for release to the market"

The T8 is not ready for release to the market

The Good: We were given a reasonable option to return multiple T7s (that were bought after the refund period) should a newly purchased T8 be able to replace them (thanks to channel isolation etc.)

The Bad: After spending significant time trying to get simple rotary encoders to work with the T8 unit, we were advised that this function is not yet available. Note: the same rotary encoders work fine with T7s. We had a range of other issues associated with getting the streaming function to work.

Suggestion: Be upfront about the limitations of the T8 unit. It would've saved us serious $ and time for coding, trialling and avoided hits to our prototyping timeline (e.g. timeline for constructing a control cabinet to adopt either multiple T7s or one T8)...

My team had a lot of respect for LJ DAQs, as a no BS robust piece of tech supported by responsive experts.... This experience has had a very negative impact on our product development and LJ's rep within our team at least.

"Review of U3-HV: Crashes (throws exceptions) too often"

Review of U3-HV. The physical connector interface (screw terminals) is very convenient. I set this up for lab testing using LabJack Python. Mine is a very simple application: read an analog input, test the value, and signal if that value changes. A single test runs for 50 hours, so a reliable device is required.

I found the Python program crashed randomly with “Got a zero length packet” when reading an input from a circuit powered from the U3 itself. I had to invest significant time to realise this was a systematic problem with the U3 interface itself. It throws exceptions which you have to catch then discard. Labjack tech support didn’t give an example exception handler or report back as to whether other units have the same problem
(despite me sending them test code to do so).
// Update: A third support person did use the code, and reported no error.

Connecting up a single output to the system under test increased the exception count to hundreds during the course of any test run. I had to opto isolate the output to reduce the common mode digital noise on the interface, thereby reducing the exception count down to a level around 100. Basically I was having to do a lot of work to make the device function properly.

Given that I have 25 years experience as a designer of “big box” acquisition systems, I am disappointed with this device. // Update: it works fine IF and ONLY IF you use an exception handler to throw away the null-packet errors.

// Update: I had some useful interaction with a third support engineer, so I have upgraded the review from 3 to 4 stars. My new conclusion is that the driver software is "hyper vigilant". It arguably shouldn't report the null packet errors. You absolutely need an exception handler (for 'self-created' problems) and then the device is fine. They have said they will update the examples which is a GOOD RESULT for future customers.

"Outstanding service to new customer"

The ordering process went smoothly. I made a mistake in my order. A LabJack team member called to point out my mistake. We corrected my order and saved me money. Also, the Tech Explorations courses are very well done and helpful in learning the technology.
