Real time
Hi! I'm an user of DI 718 Datalogger. We would like to analyze in real time the temperature data acquired by DI-178B datalogger (Sample rate 100Hz/channel) without using Windaq program. Filling a database directly... or export to real time to Excel, .csv or similar format. It is possible somehow? We need to process data extremely fast and in automated way. In case our device is not capable but there is one that can with a similar or higher sample rate and allows the processing of data online please
DI-2108 clock time is off?
I have a simple distance transducer set up with the DI-2108 to measure actuator stroke vs time. When recording data the displayed/recorded data shows quicker than actual rate. (ie. physical actuator stroke time = 5 seconds with stopwatch, WinDaq shows time for stroke =3-4 seconds). Any ideas?
DI-245 THERMOCOUPLE ISSUES
We purchased a DI-245 a while back and have finally began using it. We coupled it with Type J thermocouples from thermetrics and installed the Dataq software. An ice slurry to calibrate and we’re ready to go. All 4 sensors read the ambient temps correctly however once placed in a refrigerated test case (running between 29-38°f) the readings are roughly 18°f lower as compared with a several hand held digital thermometers. Can you offer any suggestions?
What type of software does this device use?
It looks like this device is a Windows only item? Anyone have experience with this device, such as plugging it into a Linux box?
Analog carbon monoxide sensor
Anyone know of an analog carbon monoxide sensor that works with a Dataq device?
GL840M current readings
I need to be able to read amperages of 4 different circuits. Can you attach more than one GS-DPA-AC to the GL840M to read more than two currents?
Odd behavior using CPM and counter input on DI-155
I had a DI-155 handy and hooked the count input to a Geiger Counter output. I set the channel setting to CPM. Its not doing this correctly. It does not seem to be using a minute avg. If there are 3 counts super quickly together the count jumps way up. But if those counts are spaced by a few seconds each the count is way lower even tho they are during the same minute period. If you give it 1 count per minute, it does not display this. The 1 count stays there for like 3 seconds and then goes back to
Recording Data
Im looking at the DI-1100 to record voltage, but enable to use a laptop for the specific application. Could I use a USB drive to record data and view later?
Rate Input time delay on DI-155
I am trying to use the Rate Input to record varying RPM but it appears to have an averaging time constant delay of approx 0.75 sec before it provides a steady state value after an acceleration or deceleration. Is there any way to improve upon this? I have tried varying the sample rate to no avail.
Power for sensors DI-245
is there some way that I can tap into the 5V power coming into the Datalogger (DI-245) through the miniUSB cable? I have 2 very low power sensors that need a 5V supply and ground, I would like to not add another USB cable just to provide 2W of power to 2 sensors.
Saving Data to External Drive
I'm using the DI-4108 model and need to record data onto an external drive. The problem is that all the data gets split up into multiple files instead of one single file on the drive.
DI-1120 VS DI-2108-P
I have a home built siesmometer. Its wideband. 0.01hz-40hz.. Ultra low frequencies are a really hard engineering issue because of 1/f noise and all sorts of weirdness.. Ive been using a DI-1120 since it came out years back. I just swapped to a 2108-P. The difference has been truly remarkable in the frequency band i am interested in. In fact its been shocking. The difference is not the 14bit vs 16bit. Its the far lower 1/f noise below 10hz down to 0.01hz. Where I once just had noise, signals have
DI-158U "Forgets" Default Setup
i may have originally put this in the wrong forum (DATAQ Hardware). Randomly, the DATAQ model DI-158U will "forget" the default setup. Opening a "reference file" does not transfer the settings back to the way they were set up. This is causing us to redo the settings when the program is opened. Sometimes, opening WinDaq will open correctly with the user defined settings. Other times, it opens with the out-of-the-box settings. How can we make our settings stick?

Device manager: DI-710 upload data button missing
Hi I've got a DI-710 which must be 10years old. In the latest manuals the device manager has a drop-down menu that includes commands like: start/stop upload data etc. However, the version I have (v1.61) does not have these menu options. What is that? What can I do to make these options available?
DATA Values
I have another question regarding the 4-20mA scaling. I’m setting up the scale to 0-2; 0=4mA and 2=20mA. When I retrieve the data the scaling shifts automatically from a 0 to a negative value (-1 see screen below), this changes the values that I’m logging please advise. I need the values to start at zero not at negative value. I look forward to your reply. Thanks.
csv FILE
I'm downloading information to excel as CSV data, the information transfers but the date format comes up with "######" characters, when I change the format I only get the choice of "date" or "time", I need both the date and time for reporting. How can I get that to happen. Also is there a way to change/modify/customize the name "Current", I know there is Temp, and other settings but none match what I need. Thank you for your time and help.

Anyway to calibrate thermocouples using windaq and DI-2008
Using DI-2008 with windaq to measuure some j type thermocouples. When channels are set to measure J type thermcouples they read consistently a few degrees high. However I don't see any option to calibrate this temperature. Is there a way to do this? Thanks in advance.
Data ack for live fire event.
I would like to measure temp (fast) of fire growth and then extinguishment with a water can fire extinguisher . Woodfire 1 ft by 1ft by 1ft fuel package. I assume to use Di-245, and will require suggestions on thermocouple type. Thermocouple leads would be 10-20 ft for safety of my laptop. Only need one channel, or two maybe. Would like to have chart resolution of >200hz. Greater would be better. Any help suggestions are appreciated, FF Todd Poole South Burlington Fire Department South Burlington,
DI-149 counter channel
I'm programming in Python 3.5 on Linux using the di149 protocol. I'm having problems with the counter channel. When using a PWM at 50% duty cycle It undercounts when the srate is set less than 250 Hz. For example: If I have signal set to 100Hz and srate set to the min of 11.4 Hz it will count to 3 over 1 second. When I increase the srate to 250 Hz the count will increase to 100. When I use a hall effect sensor this low count problem becomes worse. Both the PWM and hall effect sensor work as expected

NewData event handler only called once (WinDaq ActiveX with DI-148U)
I created a simple VB.NET application that accesses a DI-148U using the WinDaq ActiveX control. The form contains buttons for starting and stopping data collection and then a NewData event handler. Here's my code: Public Class Form1 Private Sub AxWinDaq1_NewData(sender As Object, e As AxWINDAQLib._DWinDaqEvents_NewDataEvent) Handles AxWinDaq1.NewData ' This event handler is called by the WinDaq Ax each time SamplesToCollect are ready for reading Dim data As Double(,)

DI-710 Power jack
Hey I just acquired a DI-710-EL device and the plan is to use it combination with a test bench in a fairly rural environment. The plan was to power it with 24VDC source which should be fine according to the data sheet, the only problem is that I need to acquire a power connection that fits. Does anyone know the exact dimensions for the DI-710 power input jack? Sincerely, PN

Software Works Only with Older Firmware
I have node.js application to read data using a DataQ DI-1110. It works fine with a DataQ firmware version of 1.09, but it fails with a firmware version of 1.17 or 1.18. These are the only firmware versions I have tried. When it fails the "Active" led turns red. This usually happens after a few seconds of collecting data. I am sampling at 1200 Hz. Why might my application not work with newer firmware? What, if anything, has changed in the API? I could not find any release notes for the firmware.
SDK access
I need to resume the data collection with the modules in SDK with C #, the problem is my interface for the data collection is in the second screen, and I have access to the data inception, but when I close this screen and return to access it, the modules do not start the data collection again, so I have to close my program completely.

DI-718B with 8B38-05 Isolated Strain Gauge Modules
Hello, I own a DI-718B data logger with 8B38-05 Isolated Strain Gauge Amplifier Modules. When hooked to a strain gauge (full-bridge), I find that the output voltage logged by the data logger is 2.5 Volts. What is the actual voltage measured across the strain gauge itself? 8B38-05: Input +/- 20 mV and Output +/- 5 V Is it just my output divided by 5 V / 20 mV = 250? Hence 2.5 V / 250 = 10 mV? Or is there a more accurate calibration done for each of the amplifier modules? I don't seem to have any calibration
Labview
Hello. We need to read analog inputs from linear potentiometers and pressure transducers and we think your DAQ could be ok. But we need also to write our own GUI to configure the input and to elaborate incoming datas. Is your systems only compatible with software like visual net or it is possible to use also labview? Thanks. Ing. Alessandro Battisti.

I've tried: Turn off Windows Firewall service Disconnected all Ethernet cables Assign first port static IP address Connect Ethernet cable from computer
Minimum Sample Rate when using Auto Start on System Boot
Greetings. I am trying to setup Windaq to auto-start when my PC boots up. I'm having decent success following the post linked below, with one exception. When Windaq launches, I get a popup telling me "sample rate [per channel] was raised to 0.0762 (minimum sample rate)." However, the data file I'm using to provide startup parameters has 4 channels enabled, a minimum sample rate of 0.00305/channel and a max of 100/channel. My desired rate is 0.016667 (1 sample per minute). From the blog: "[-F[d:path]setupfile]

.NET SDK
Hi, I am looking for a online help for the V2 (.NET) SDK, similar to https://www.dataq.com/resources/installations/web-help/sdk/ which refers exclusively to the V1 SDK. I am trying to write a C# software for communication to the DI-1110, which is not supported by the V1 SDK. Some C# sample code would also be helpful (the VB code samples are not very helpful) thanks Ralf
