Hi All,
I see this latest firmware (8.06) has a fix for improved logging speed. Can someone give me specifics on this improvement. I don't see anything in known issues.
Thanks

I have a DT80-2 series and DeLogger5V1R5 software, but I can not configure option "n+R(II)" to read (R1+R2+Rc) with a 4-wire Carlson sensor configuration (figure 83, page 202 of DT80 User's Manual UM-0085-A7).
Thanks
Good morning!
I use DT80 + CEM20. I want to measure a temperature with a thermocouple type T linked in CEM20. I have the following error: 8e9. What I'm suppose to do to cancel this error ?
Best regard,

From this forum, I got a tip on using Cybertec 1000 as the GPRS modem to FTP data from DT80. Until now I am very happy with the issue free interfacing.
Now I am looking for a satellite modem to interface with DT80. Anybody interfaced DT80 with satellite modem before? What satellite modem you used?
Advance thanks.
Hi,
I'm using a DT85 for reading HIC stress cells containing 12 strain gauges. Gauges can be temperature compensated afterwards with a separate RTD instead of a dummy gauge.
Two common grounds are available too, thus making three-wire quarter-bridge reading method possible. I'm wondering using just a one single precision bridge completion resistor to read all gauge channels.

Hello!
I have several DT85 loggers installed to working on batteries. They are equipped with SMSX modem and it is powered by the relay. Somehow the logger do not go to sleep mode every now and then, and it runs the battery flat.
I think that the problem is related to the modem that is scheduled to be on ones a week for two hours. However, I am not sure. Problem does not occur all the ti
Hi All,
We have dataTakers DT615 and DT80G. We are trying to connect 1000 ton load cell with these dataTakers. For that we used Bridge channel type with config 15 and span also (like mentioned in manual and video tutorial).
But the readings are not reliable. readings are changing. Not stable. If anyone knew to solve this problem. Please reply to me.
Thank you

Hi,
We have DT80G datataker. We are trying to measure the temperature of the concrete using thermocouple. We able to get temperature reading which thermocouples directly connect with DT80G datataker but which are connect in CEM20 giving error reading (eg: 8e9).
We read user manual, under CEM20 reference temperature, Ask to type nREFT. We don't know where to type. There is no detail abou
Hi,
I'm running my DT80 off an external supply from a vehicle, which is on or off when the vehicle has started or stopped respectively. The power supply is also connected to digital channel 8.
I'm logging schedule A at 1 second intervals while digital input 8 is high. I want DT80 to stop logging (which I have achieved) and go to sleep once the external power source stops (which I've man
Hi,
I have an application where I need to "sniff", and log all MODBUS traffic on RS485 2-wire. The application that DT80 will be used will have one MODBUS Master, and 4 MODBUS Slave Devices.
DT80 will ONLY monitor the link and log the data. The link runs at 9600 baud. The MODBUS Master only will request one register at a time from each slave device. I have tried various different ways o
Hello,
I have the following questions that I have not been able to find answers to in the manual, FAQ, or forum:
When unloading from a DT80(series 2) to an existing file, is the file overwritten or appended?
If appended, is only new data since the last unload added or can the file end up with duplicate records?
Thanks for your help,
Jason
My dataTaker unit battery cannot fully charge. Every time I charge it to 100% and a arrow and NC will come out once I remove the direct power supply, the battery drop to 44% and keep dropping.
I used it to connect to 8 thermocouple wires and the data take every 10s. The battery can last for 2 hour and 15 mins approximately. Yet, sometimes it just last 1 hours. Some might explain to me? How c
I have problems with thermocouples type T on CEM20. The readings are erroneous and might change between -6.0 to 26.8 C between two scans (RA1M) even though that soil temperature is a stable substrate.
I have both tried single ended and differential connection, but neither of them works. I have checked/logged the 1REFT and it is stable. If I use an immediate scan, it seems that the measuremen
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

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
