How fast can you read thermocouple data? The manual says it is a sum of: Measurement time, processing time, communications time and logger preparation time.
But it does not provided values for all of these.
So how fast can you log analogue data without accuracy issues or channel ghosting? Is there a formula?

Dear all
We have a DT800 since many years and we use it a few times for temperature measurings
Now, i have a new chalenge to build a weather station with some sensores the we have in the lab
The sensors are:
SP Lite2 Pyranometer; sensitivity 68 uV/W.m-2
Thies anemometer 0.5-40m/s, a T351-TR Thermistor, a very old pluviometer that I will calibrate it.
And some k thermocouples
Hi
Can you recommend suitable main battery replacements for:
A) DT80
B) DT85
I know the DT80 is 1.2aH and the DT85 is 4aH but not sure of the physical sizes (The loggers are offshore so unable to look!)
Many thanks

Hello, I was trying to add a new channel to the current job on my DT80, and when I hit download, it wiped the job completely off the device. Is there a way to recover the job? Or do I have to start all over again?

Hi
We have a DT51 we dusted off. The problem I have is that when you startup the logger there are some default scans, spans and switch settings, if I delete the scans and write new scan, when I restart the logger or cycle the power, the logger defaults back to the "built-in" scan and switches.
Is there a setting or switch where i can stop this from happening?
Thanks,
Paul
When running a test on one of our DT80s, it sometimes fails on Vos 3W II. What does that mean and is it repairable?
Is there a list available of the test line items and what they represent?
VEXT 13.4 V
VBAT (6V) 6.50 V PASS
IBAT +4 mA PASS
VSYS 7.05 V PASS
VLITH (3.6V) 3.63 V PASS

Hi fellow users,
How can I execute an exponential function in a calculation dEX-2 / DT85?
Thanks in advance.

Ferdi.
I have a DT80 connected to a CEM20 (id#2). The CEM20 has one 4 wire RTD and six 3-wire RTDs connected to it, reading in at about 1Hz.
They are Pt385 RTDs with 100 ohm resistance at 0C. I'm using the II parameter to excite at 2.5mA and, for the moment I am just trying to read ambient temperatures.
The 3 wire RTDs all read between 16 and 17C while the 4 wire reads 22C, when they should al

Hello,
We have multiple DT80M datalogger over the country and for some reason, they many of them have started to lost the SIM pin code. This affects only for this settings, all others ones are fine. It happens randomly, between month or like once in a year. After entering the SIM Pin again, everythings works like excepted. This phenomen was not going on a couple of years ago with these logger

Hi, I have a project where I have 2 DT80GW units and I wish to connect the two together, one of which I want to send off data via a Email. I wish to use the integrated WiFi to connect the two together and then thinking of using a 4-G modem to send off data and alarms? Is it possible to link the units together this way?

Hello,
The integrated DT80 in our system has lost its configuration (no current job).
It seems thats the DT80 have run out of memory space, and is unable to load the configurated jobs at start up. As descibded in its logs with the error E116 :

Hello, I am new to the DT82em so please forgive my ignorance. I have been asked by my company who own the Datataker to wipe the memory and create a new schedule. The issue is the last person has password protected the unit and we need to wipe the device. WE want to lose the data and software. The version number is a 9.22.
Thank you
Hi, We're using DT85G Series 4 for monitoring settlement and strain gauge readings.
I was wondering if anyone here can help me monitor the data using microsoft excel (Data connections). For now, we are more inclined in using Delogger5 as it is easier to program than Dex.
For now we are monitoring the data using the Txt window in Delogger5 but we prefer to do it Microsoft excel for data
Hello,
I hope you are well.
I have a DT85 series 4 datalogger and I want to measure the torque + rotation speed + power from my torque sensor, which has a 12 pin connector (picture attached). I have also attached the manual for the torque meter (DRBK from applied measurements). I have also attached the datalogger manual.
Any help would be greatly appreciated.
Thanks!

Hello,
I work in information security in a university. One of our students wants to install dEx 2.0 v2.1.25. We have a hard time finding information to validate the safety of your software. Do you have an EULA and a privacy policy ? In what country are you located. Do you update you software as soon as a vulnerability is found ? Is there a way to have automatic updates configured ?

DT85M failed to communicate via SIM with message: "Modem will retry [SIM problem]".
SIM was removed and reinserted and slide catch engaged and checked that was fully engaged.
SIM had been working for a number of years without problem then the issue started a couple of weeks ago when emails containing data ceased.

Hi
I am working on a train project presently trying to program my dt80m3-3 with code to take in GPS data and use that data to monitor and record train speed and trigger appropriate data storage responses depending on train stop/run. Also want to record GPS position.
Can someone please assist with some appropriate coding. I am using deX-2.
Hi, I have a couple of DataTaker DT80's (one series 2, one series 4).
I plugged the S4 into a Windows 10 PC and Windows said it was installing a driver. Would this be DTusb or do I need to physically download it (where from?) and install it first?
I see from other posts that DEX 2.0 avoids the need for Flash. Where is the download for DEX2.0? Do I need to upgrade the DT80 firmware firs
Hi All
I goofed today, and set the logging interval much shorter than usual (2 vs my usual 15 or 30 seconds), ran out of memory half way through my trial and overwrote the early data.
I have downloaded and dumped the DDB - it's still missing the first two hours or so, so I'm fairly sure they are gone.
I was watching the data in a DEX2 dashboard while it was being collected - long shot
Hi
My DT80 series 2 just stopped responding
The sample light, disk and power lights are on but no display
It was a brand new logger (2009?) . I had updated to latest firmware.
It was working fine for about 3 weeks
Anyone got any ideas ? A hard reset has not fixed it
thanks

Hi @all,
I'm currently evaluating a DT80M Datataker Logger for the use with our SDI12 Moisture sensors. Logging the data works fine so far but I hit a strange problem uploading the data to an FTP server. Every time the Logger tries to upload data, it fails with some strange 'FTP: server out of sync (-3)' error.

Hi all, I last set up my DT85 on dex-2 about six months ago and have unfortunately forgotten how to do it. I am sure that the IP address and port 80 are fine but think there is something to do with the template that I am missing? Could any please provide me with the chronological steps I need to do as at the moment it keeps saying my DT85 is offline.
Thanks :)
Hi all
One of our DT85 stop working yesterday.
The display is working(has display when bootstrap) but nothing display.
Sample, disk and power LED is On.
Hard reboot is not working too.
Any advices?
