Hi,

I am using a DT80 to log one analog 4-20 mA and two digital channels. I set the sampling frequency to 20 samples per second but I only get between two and four samples per second, randomly. Don't get why?

Does anyone have any tips on how to get faster sampling? If I read the data sheet the DT80 should handle up to 25 Hz sampling.

Hi,

I have a customer here who wishes to control the temperature of a water bath remotely ie. two thermocouples measuring the process temperature are connected to a dataTaker (suitable model) which is logging the temperatures.

A water bath with heating/cooling functions and a thermocouple is located remotely for example 200 or 300 miles away. The water bath temperature must be controlle

Hi folks,

I have an application monitoring just about everything on a lake and now the client is asking for daily pictures of surrounding fauna, in particular the reeds and other normal aquatic growth.

Only one still shot per day would be required and download remotely is not needed so file size not really an issue, although I believe VGA resolution would be good enough. I'm wondering i

Hi Guys,

We were looking for a device to act similar to an accelerometer. We hooked a couple of wires to a suspended pipe and then configured an input into DT80 for frequency.

After banging the pipe, DT80 registered a distinct frequency which was pretty close to what we were hearing (about 350 - 400 Hz). How does the DT80 register this? What accuracy is possible with the frequency input

I've got an issue with the low-power mode on the DT80. It's probably due to my misunderstanding of how it works, so I'd appreciate some help!

I have a very simple setup with a DT80 connected to a sensor on a digital input and increment a counter each time the sensor is activated. DT80 is externally-powered (through the screw-terminal connector as recommended in the manual) and also has the b

Hi,

I have a DT80 in a remote location and due to an extended power failure, it stopped logging. I have tried to reprogram it using a USB stick but no luck so far - it comes up with "Cannot Log No Space".

So by the looks the memory is already allocated from the previous program and in the new program (which is basically the same) the bit that sets the Data Store Size is causing the prob

Has anyone tried using the s::can spectrometer with the DT80? I believe the s::can has MODBUS but can only function as a MODBUS slave and DT80 has MODBUS but it too functions as a MODBUS slave. So can I conclude that DT80 and s:: cannot talk?

I'm starting to get problems with a couple of our remote monitoring stations that use DT80s(we have approx 30 such units located all over the place) - these particular loggers are currently operating with Firmware version 6.06.

Both have a single program running which logs data on a 30 minute cycle. Problem, when connect to the logger I cannot access the data on the card, nor can I access th

I have been playing around with the new V7 firmware to try and overcome the issue of not knowing if the FTP 'push' of a file was successful.

Short story: It seems to work using the new 29SV variable in a simple alarm. I figured that every value below 0 for 29SV was bad and everything 0 or higher was OK, so used a simple regular alarm test every logging scan.

If the last FTP attempt was

Can anyone tell me how to do a linear regression (Y=mX+b) for two channels on a DT85? !

Dear Sir,

Last week, I already bought a new DT80 with new firmware 6.22. I got small problem here. Why i can't connect DT80 via RS232 null modem cable?.

Normally, i don't have any problem with this DT80. It's, new brand of DT80 had any changes with their command.

Hi,

I'm having endless troubles getting results from the dataTaker. I wish to email the logged data to myself. DT80 won't have DeLogger connection but will have have Ethernet. Does it need DeLogger running or can it do export/email automatically with a schedule? I have got the DLPMessageHandler.exe working (it emails fine) but don't know what the command is for making an email an action.

Hi All,

I am still battling away on the project that I mentioned in a previous post, but as I have progressed slightly I thought it would be better in a new thread. My application is using a DT80 (and now also a DT85) to log data and then upload to a web server via FTP.

I am struggling to make the FTP part work. At the moment I have a DT80 connected to the internet via a Belkin router,

Hi All,

Here's a quick question... I am looking into using some satellite telemetry to send a large bunch of data daily and want to minimize transmission time to cut costs, one sure way is to reduce the file size being sent.

The data being a csv file should be able to be "zipped" substantially before being sent - is it possible to implement some form of data compression in the DT80? If

Hi All,

I am currently working on a D T80 project which involves numerous DT80s uploading data to a web server via a GPRS modem. I think I can transfer the data by opening an ftp connection to the server and then unloading using 'U' directly into a text file on the server.

Is there any reason to think that this might not work? Also, is there any way that the DT80 can handle strings rece

Hi Everyone,

Is there an easy way of finding the number of CV's used or a list? Up to now I've been looking through the program but this is tedious when the numbers are large, scattered or one becomes distracted...

Cheers,

Dear Sir,

We are facing he following problems in DT80 (being used in Automatic Weather Monitoring Station for acquiring weather information from various sensors)

DT80 is acquiring erroneous data from some of the sensors randomly.It acquires underrange or overrange data fro Temperature and wind direction sensors (resistance),Relative humidity and solar radiation sensors (voltage) etc. Th

Hi everyone,

I'm quite new to dataTaker. Sorry if my questions seem like rambling but would like to let you in on the details so hopefully someone might diagnose the problem.

Anyhow I seem to have problems connecting to the DT80 using my laptop. I have followed the instructions by the book so I can't seem to troubleshoot my problem.

I'm using Ethernet connection to connect my lapto

When I try to connect to my DT80 with an RS232 standard comms cable, I can't. Is there anyone who knows why this happens?

Thanks,
Sam Foster

I have a DT80 data logger and I have plugged it into our home router with an Ethernet cable. In about 3 months we are planning to go to England. How can I access the DT80 overseas? I need a very detailed description of what I need to do.

Yours truly,
