Hi all
I have wired the DT800 for 1/4 bridges on a channel pair (manual page 176).
I have attached a 120 gauge on channel 1+
Reading ppm with 1+BGI...... result: 55 ppm (+- 5ppm)
Reading ppm with 1+BGV......result: 160 ppm (+-15 ppm)
Any takes which result might be right an why?
Thanks, Claudio

For those that are not aware, you can run your DT800 with DeLogger 5 on a windows 7 PC by running XP Mode in Windows Virtual PC.
These are all downloadable from the microsoft site:

I am repurposing several DT800's and my trials sofar indicate that they will be able to do a great job. But not everything is making sense to me.
To put things in context, I would like each logger to measure between 10 and 20 voltage signals, once per second, within the first 50 ms, and the loggers synchronized to within 10 ms of each other.
1) I figured out that the timestamp on the data

I'm experimentally studying the self-heating of a special type of resistors. Typically I'm using a DT800 to record differential DC voltages as a "V" channel between, for example, 1+ and 1- terminals, or 3+ and 3-, et cetera, in a simple resistor network. In my experiment I gradually reduce the power supply voltage driving the entire network, over time. Unfortunately my approach is fairly vulnerab
Dear Roger,
When my DT85GM upgraded firmware 9.08,why the connection of modem test failed in SIM access?
The connection of modem was normal before upgraded.
And when I use USB port to connecting to the web interface,some function can't working.

Hello,
We have a DT85M.
We have a job which sends every 24h a SMTP email.
As the carrier is T-mobile, we set in the code APN as following:

We want to use the same job but using a SIM from another carrier, AT&T.
The phone subscription is data only (we cannot send text or call).
The only modification in the code should be the APN, to co

Hi everyone
It´s the first time I use a datataker and i have already a problem.
I need to change the serial sensor port speed during logging because i have to communicate with two different devices that have 2 different speed. I tried in a manual channel something like this:

Dear Sir,
I have an unused logger left for about six months, when powering it back on, the firmware seems to have corrupted / lost.
I was trying reload the firmware by using the DeTransfer program / a USB drive without success.
The logger ignores my USB drive (FAT) and simply return to flashing of all of the 4 lights when i press the ok/edit button.

Dear Roger,
I am deploying a few DT85GM in Hong Kong, and I am experiencing "SIM Problem" with simcards from Smartone HK.
I first tested the DT85GM with my own personal simcard (PCCW HK) and it worked smoothly, but when Smartone HK gave me 5 brand new sims they all have "sim problem" when the modem was starting up.
I tested the 5 sims in my phone and they appeared to work without probl

My DT85 is scanning data every 15s and logging the average of 4 readings every minute.
At 0758 on 5th May, after weeks of working satisfactorily, it missed a reading, and the following reading at 0759 was corrupt.
The Service log is attached.
How do I stop this happening again?

Hello,
I have a DT85M with V9.16 that will run for 10-30 secs, shut itself off, and then restart with a "Power Loss" message. Whether you clear the "Attn" LED or not, it will sample for a few secs and then repeat the process over again continuously until power is removed. After one of the restarts, the unit displayed the "SW Exception" error. This set up worked a few weeks ago. The unit will

Hi All,
I am currently in the process of connecting up 20 strain gauges to a CEM20. In order to help reduce electrostatically induce noise, which can be a problem with my setup, I need to ground all of the shields at the Data Taker end. Although there is an analogue ground connection on the DT85, I do not see one on the CEM20. I could connect all of the shields up to the DT85, however this wi

I am doing a job at the moment, where we require 3 remote dataloggers, to provide continuous live data. I am wondering how do I use the internal modem as the modbus interface between the DT82EM and the SCADA/PLC,
I understand the DT82EM will have to have a fixed I.P. address attached to it, or else go in through a Dynamic DNS, but what i am wondering is,
Is the logger automatical
Hello Everybody,
I have a problem about configuring DDNS for DataTaker DT82EM
I am using a SIM which support 3G (Made by Viettel in VietNam). This SIM has been active and it has “IP public address”. It change IP address after the modem DT8x is restarted.
I create an account (nth_ngo) with DDNS service provider: no-ip.com.

Hello Everybody,
I am using deX to configure to DT82EM.
My SIM PIN is " 0000". BUT When i type this pin to deX and save to logger, the deX only shows "0". So the configuration is wrong
I have change SIM PIN "0000" to " 1234" . The configuration is OK.
Could you tell me about this problem ?
Thank you very much

I am finding a sensor which measure Flow Rate, Water Velocity and it have to connect to DT82EM via SDI-12 interface. It is Ultrasonic Doppler sensor.
If anybody knows that sensor (it have to connect to DT82EM), tell me about that please.

Hi,
I am new to DT82EM so apologies if this is an obvious question.
I would like to set a trigger that is set when an SMS is received at the internal modem of the DT82EM. Is this possible?
I had a look at the FAQ, forum, technical notes, etc but have not found anything relevant.
Thank you for your help.

Just purchased a DT82EM and having huge issues with it. I upgraded to 9.10 firmware that i was told would resolve the resetting issue.
Essentially as the modem is being tested when it gets to the FTP section the datataker resets and flashes the lights. When it finishes rebooting it displays a message that the datataker was restarted and that memory was cleared.
Any thoughts on how to fix t

When I define an action channel "Email logged data" in dEX the program seems to check the validity of the receiver address, that is reasonable.
One of our customers wants to use an address which local part (left on the @) consists of numbers only (e.g. 12345@domain.de).
In this case the test is too strict, the address is only accepted if at least one character is included.
This is not a

We have some DT82EM with older Firmware.
I have upgraded the logger firmware to version V9.18 first, then the modem firmware to version R7.53 (both downloaded from the Datataker website).
After updating the modem the display says "Firmware update failed", but the modem seems to work properly.
I checked the firmware version with

and got the answer:

dear sir,
could you please provide full details for configuring DT82EM for noip.com
so that we can access DT82EM from remote using specific domain name of no ip.
pl provide complete settings. i am using vodafone sim right now in internal modem.
