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?
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
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 every time. 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 the default 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.

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
DI-1110 counter function with flow meter K factor
using DI-1110. I want to use a flow meter with a pulse output. Can I program unit to give me a output in gpm? I have a K factor for the meter, which gives me counts per gallon. Is there a way to do the math and display "GPM" units on graph?? thanks
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
problems with DI-1100
well, i have 2 devices di-1100, and i work with it at same time for data acquisition in a program in C#, and work fine, i create two extensions to work one for each one, but the problem is when stop it, sometimes stop it well, but sometimes the devices don't go out of the state of acquisition, and the message of DataqSdk1_ControlError appears when i start again my program, in the last version of the forum someone told me, that i need to restart the computer for erase the memory, and i does, but i
Autosaving Data

how to set di-145 sample rate
I have a di-145, i want to change the device's default sample rate, now i use the example(DI-145,c#.vb) to try, but i find it can not change the sample rate, i use the following words; DI_145.SampleRatePerChannel=10.0; lblSamplingRate.Text = DI_145.SampleRatePerChannel.ToString("F3") but the label always displays 60.00. so i want to konw how to set sample rate,i need some help. Thanks!

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.
Question on programming with VB.Net
I am wondering if anyone knows an easy way to read from the DI-1100 and fill into a Datagridview? I am currently trying different ideas but I keep ending up with multiple values in one row for one channel. Thank you for your time and help.
DI 808 live stream
Is there a way to get the DI 808 to continuously send a live stream to a website so I can view the data in real time? I have a device doing this currently, it streams out an XML to my website. I prefer the user interface of the DI808 to my unit and would love to make it work for me. Is this at all possible or do you offer another unit that can? I need to be able to measure 4 pressures and 2 rate's
Using a DI718B on a computer with 2 Ethernet ports
Is there a way to get Hardware Manager to recognize directly-attached DI-718Bs when the computer has two ethernet ports? I'm trying to keep my DATAQ stuff segregated from the corporate LAN. Ideally, the setup would be: One Ethernet port connected to DI-718B for data acquisition. One Ethernet port connected to corporate LAN to access company resources. I've tried: Turn off Windows Firewall service Disconnected all Ethernet cables Assign first port static IP address Connect Ethernet cable from computer
DI-245 Serial communication receiver code
Hi, I want to use labview programming for DI-245. Because I need to record the data with YOKOGAWA WT310E(power meter). Now I connected the YOKOGAWA power meter with LABview and can read the data from it. I get the DI-245 communicate program, it is 00 41 32 00 4E 5A 00 4E 30(hexadecimal). And the baud rate is 19200. I sent 00 41 32 00 4E 5A 00 4E 30 from PC to DI-245 by serial debugging assistant. And get the reply from DI-245. I short 4channel positive input and negative input. Adjust
