I would like to log the wind data of an ultrasonic wind sensor type Young 81000, using a DT80 series 2 (most recent firmware installed). The wind sensor has been programmed as follows:
it waits for the poll string "MA!"
it responds with the following string: " 0.52 2.7 -4.4 16.87 0" meaning: windspeed, azimuth, elevation, temperature, error code format: real[m/s], real[deg], real[m], real[d
Please advise before I burn the logger, is it possible to measure the voltage from a solar module using a DT80 directly without putting attenuator?
I'm looking at a voltage of 20-25 V from a module. The manual says one can measure up to 30V. I want to be sure. Please advise.

Good morning,
I have a problem with a DT80. I have a potentiometer and I want to measure the voltage drop across it. I have a external source with 9V connect to potentiometer.
I take the measurement between the positive terminal of the source and the central terminal of potentiometer. I would have to obtain a measure of 4,5V but the measure that I obtain in the datataker is 2V approxima
Hi,
We use a DT85 logger at various locations on a regular basis for logging temperature in retorts. The logger works fine, except in some location where power surges in the factory occured, we find a spike appears in our logged data.
The logger power supply is protected by a power surge protector. Is is possible that this is coming from the earth connection? Is there some way of stoppi
I recently purchased a DT80 series 2 datataker, the seller did the installations for me on my laptop. At first i managed to go through the part 1 training exercise.
Later i could not manage to go over the exercise. From the laptop the information i get is:
Warning: could not open serial port
Warning could not detect baud rate for serial part
How can i resolve this?
Thanks

I have a DT80 in a remote area with only GPRS network available. Through GPRS, I want to open the remote DT80 web page. I cannot install a GPRS static IP on the DT80 because it cost $500 in my country and none of my customers can afford it.
So I am thinking of using existing dynamic GPRS and DDNS (dyndns.com). However from my existing noobish GPRS understanding, this system will not work. Ha
Hi,
I have to use an analog channel as a digital one. Do I have to supply power with an external source? (may be a 12V or 24 VDC)
Thanks, Dumnall
P.S. Any news about Windows 7 vs DeLogger?
We got a wave sensor and it only outputs serial binary data. Can dt80 read serial binary data and decode it into decimal CV?
Messages from the WaveRadar REX consist of fixed length strings of binary values which are sent over a half-duplex link. Output messages will utilize the data link for approximately 20 ms every 250 ms and are repeated every 250 ms (4Hz).
Any message sent to the rad
I got dataTaker to push files to a FTP server. Now the client wants the data to be display in real time in a software display. Ughhh...
Have you guys seen any real time display software that can intercept data from FTP stream directly? Or read the latest data from the files in a FTP server?
Like to know have this been done before. Usually real time software displays use data from TCP/IP
Hi,
We have in excess of 20 of your loggers around our plant all connected to our LAN. My question is, can we setup a daily file (.txt or .csv) to be appended by all the loggers alarms? Far easier to view one log file than connect to each logger.
Thanks,
Steve
Hi guys,
I have a DT80 onsite permanently connected via Ethernet to a laptop running Delogger 5. The laptop is just showing the chart and the trend of a process over a couple of hours.
Whenever I access DT80 via a dial in modem, Ethernet connection drops out, and it needs to be manually reconnected by me which requires a site visit. Is this a normal occurrence or am I missing something
I cant connect DT80 through USB using Delogger5, it say
warning : connection refused Find device check failure
warning : datataker not found on connection
I had set what ever it told install driver... select the correct port but it fail, can someone help me pls thanks
*I am using Windows 7 64 bit.
Hi,
We have a number of DT80's in the field, the people that previously setup DT80's are no longer available. Is there a way to automate the collection of the running code (not the data) from the DT80's so I can get the field crews to recover the code?
Thanks,

Hello,
I am trying to take some measurements with some equipment that require a voltage input, and am having some trouble setting this up correctly with DT85 series 2.
According to what I have read, I thought I could do this by using the external input location. I have a regulated 10V source plugged into the External plug. and set up a channel for a load cell and configured with "E" for
I'm currently working on a 4 channels DT80 that is reading too low on the 10 ohm range. Is there a layout of the 4 internal variable resistors available? I'd prefer to not have to do the trial and error method, I haven't found anything in the available manuals.
Hi folks.
At the moment I am getting a signal back from my turbine meter into DT80 using a hall effect sensor and the high speed counter but would really like to do it with a magnetic pickup. My pickup outputs around about 50mV.
Is it possible to bring the magnetic pickup into DT80, read it as a frequency and then work out both a total volume and a flow rate? I have gotten both of these
Hello,
I am using a DT80 to sample an ultrasonic anemometer (Gill Instruments WindMasterPro) at 10 Hz, testing using DeLogger v5. I've also tested the serial connection using DeTransfer, after reading this forum - seems to be working fine.
I'm finding that I get a few seconds of measurements received at full rate (10 Hz). Then I get an error signal: 'serial sensor scan error at control
Hi all,
I have a DT80 inquiry for monitoring PN systems and was wondering is there an examples of this done within the applications notes.

Hi,
I tried this on script; s1=0,100,0,1"m" where my sensor output should in range 0-1v, but why i got -ve value on "m"? I thought the lowest it can be is 0m. How to only return minimum value is 0?

Hi,
I am programming DT85 series 2 dataTaker using DeLogger 5. My purpose is to log the change of state of some 80 inputs.I use CEM20 along with DT85 and use analog state inputs.
I don't need a continuous log, I only need logging when the inputs state changes.I use the alarms on all the channels, assign alarm numbers and set point 1 with conditional test as greater than or equal to set p
Hi,
Is it possible to control a pump having a 0-5V control wire using DT80? I would like to regulate the flow rate based upon the temperature of the flow stream. DT80 already monitors said temperature.
Thanks and regards,

Hi,
I'm trying to use digital channels 5D, 6D, 7D and 8D to monitoring digital status like I usually do with 1D, 2D, 3D, 4D. The channels from 1D to 4D work correctly but the channels from 5D to 8D don't work at all: they return digital status 0 (zero) with open and close circuit.
All the channels have the same command line so I don't understand why they do not work. There something tha
Hi guys,
We are still on the angular velocity problem. We are toying with the idea of using a rotary phase encoder and counting the pulses. With an encoder that produces 5000 pulses per revolution, it works out at 14.8 pulses per degree of travel. At 30 RPM that is roughly 14.8 pulses in 5 milliseconds.
Are we trying to get to much out of the DT80? We can go to lower encoder pulse rates
Hi Guys,
We are trying to log the change of a resistance versus time to calculate an angular velocity. I have managed to obtain a logging rate of approx 50 ms. Is it possible to go lower then this, and if so how?
Cheers,

Hi,
I wish to use the relay outputs A and B to power an external device when a certain condition is met. To test the functioning of the relay, I tried activating the relay by sending a simple 1RELAY=1 command and measuring the resistance between terminals A and B, thinking that the resistance should be close to zero when the relay is activated.
However, this was not the case (the multim
I am trying to use a dataTaker (DT80) to interrogate a device with a serial comms output (RS232). I am wondering is it possible to use a dataTaker to ask a device for a status check and then save the data from the interrogation?
For example if I wanted to gain the status of a modem via a hyperterminal session, I would use the code AT&V. I would then get the following output:
ACTIVE
Dear Sir,
I'm now using DT85 for data logging. I got problem and cannot get reading when I connect Vaisala HMP-50 humidity and temperature probe to DT85.
I used DT85 only since one month ago and I'm quite new. Can anyone help me about this problem? Both physical installation and software programming.
Best regards,
Rio
Hi,
I have a DT85 set up that monitors four separate temperatures using 1/8" Diameter Type K thermocouples. The logger is set up a couple of meters away from the thermocouples and I usually leave my laptop connected to the data logger to display a real time graph of the temperatures during experimental runs.
I encountered a problem today involving interference of the thermocouple signal
Morning folks.
I am having some trouble with the DT80 and my 4-20mA inputs. I am trying to hook them up across the + & - terminals and am getting nowhere. I have tried using and external 10 Ohm resistor but to no avail.
I am also using the Prog1.DT80 window for my scaling. I have read the manual that came with the logger but it only seems to reference the Text programming option. Ca
Hello,
I am currently undergoing a project which aims to carry out load test for different materials so as to measure the amount of force exerted on the material upon impact.
I am using a DT80 datalogger and a load cell and a 2-channel transducer. The load cell I am using has details found here: http://www.pt-global.com/index.php?shop_name=pt&func=14&DPT=p&DPI=236&DCI=89
