Recently i notice and read that to be able to see the configuration of your DT80 on the web is to migrate it in DEX2. Does it mean you will not be able to open the web portal since Adobe Flash is already EOL? Besides using DEX2 what other alternative can we use if we want to access the GUI on Web portal as we are accessing the dt80 via internet. Hope for your kind response. Thanks

i have problem when loading a program from a saved file.everytime i load the program,it will alter the calculation output(result) that will cause error when uploading the program to everytime i want to resend the program to datataker,i need to re-do the calculation one by one. hope for a solution for this .thank you

Good day

I am working with the DT85W Series 4 (V9.22).

I want to create an "internal graph" while the program is running using the following equation:

=345*LOG((8xTime)+1)+Ambient temperature

I think I will be able to create the graph but I do not know how to create "Time" to be a variable.

On the DT500 there was an option to create a channel named "Time Variable". This allow

I have been trying to use dex-2 to connect to our DT85Ms. I am using a USB cable straight into the device.

When I try to connect, using the port and IP address from DtUSB, it will not find the device. Looking at the code found in the "Development Tools", it keeps throwing back a 403 error. Specifically:

"Failed to load resource: the server responded with a status of 403 (Forbi
We have to do auto shunt calibration process through program.
For example,
If we have Strain-1, then after offset removing process as we connect the 17134 Ohm or 174650 Ohm then strain value must come as 10000 or 1000 macrostrain, but unfortunately there again some offset for individual channel offset id differ from each other, So we want to remove this offset ,
Please suggest and suppor

is it possible to use the dEX2.0 software together with the dEX webversion? Since we use the software, the webversion stays empty.

We use text-based programmes, but the command line interface of the software has a limited amount of characters, so we can't send a complete programme. In the webversion, this worked fine.

Best regards

Can anyone please give me an idea about how we connect three wire strain gauges to the data taker and what bridge configuration we should follow? I am using a DT85 model data taker.

If anyone can explain the basic things related to this or provide some useful links, it would be a great help as I am very new to data taker.

Thank You.

I've been using a DT85 series 4 for logging several 4:20mA signals, and I'm configuring the DT-85 using DEX-2.
the DT85 had displayed all the signal correctly on its display, however when I tried sending a CSV file using FTP, nothing was sent to the FTP server.

her is the DXC

Dear Team,
I'm facing to the Flash that is out of date. I can not access to Dex software to configure data taker DT80. Please help to instruct me to configure it.

I am monitoring an air conditioning system for occasional trips of the compressor overload. While monitoring all the usual things like temperatures and pressures and compressor current at 30 second intervals, I also want to monitor the three compressor current transducers "as fast as possible" for 2 seconds following the contactor closure. I've looked at scanning fast in the manual (under "Contin

Hi, I use DT80W-S4 to measure analog (4-20mA) Water Level Sensor. When I calculate the mA that DataTaker measure is different from what the sensor output mA. How to make DT measure the same mA value as what sensor output? I did adjust the ohm of the 100ohm resistor but the resistor value only can be input round number.

Hello i habe trouble with my Programm on my DT85M
Actually it is my first Project with a Datataker

I need to read 200 soil moisture sensors.
Each sensor has 4 variables to measure
175 of them are with modbus where i have to recalculate 2 of the values
25 are with SDI12
The Sensors work and i can communicate with all of them.
So i have 1150 values to measure with this sensor

While troubleshooting a strange voltage reading on a DT85 S3, I narrowed it down to this. When I measured the reading outside of a schedule, it measured the voltage correctly. When the same line of code was used in a schedule, it measured the incorrect value.

Actual voltage measured with a Fluke multimeter at the DT85
terminals: 44.7 mV
Voltage manually measured by DT85 in DeTransfer without

Hello i am new with Datataker

I just installed dex 2.1.18 but it does not find my DT85M.
With firefox and the Flash player i can programm and find the Logger, but it works awfully slow.

The logger is connected via USB.
dtUSB shows the loggers IP.

I would be very pleased if somebody can give me a hint what's wrong with my setup.

I use Windows 10 Logger firmware version is 9.2

Can the Ethernet Port on the DT85 be used to send a Modbus command to a TCP/IP Modbus Server Device (e.g. Sensor configured as TCP/IP Modbus Server) as well as receive a Modbus command from the TCP/IP Modbus Client Device (e.g. SCADA) simultaneously?



I am trying to configure a sensor to record data using a DT82I.

I have the sensor connected to the green serial connector on the front of the logger. The sensor communicates using MODBUS.

I am attempting to use the following code to log the temperature data from the sensor as 1CV:

hi all,
I am having difficulty being able to log onto the Data Taker I have, I have downloaded the dEX2 and the DtUsb software. The computer sees the Data Taker as it shows up in the devices tree, and when I connect with the USB I can see the IP., but again I am unable to log into the Data Taker .

Does anyone have any solutions?

Many thanks

Hi! Noob here. I'm using my DT80 for simple temperature measurements, succesfully getting two simultaneous signals in ports 1 & 2. My issue is that I want to trigger logging schedules, i.e. by having a circuit in the upper left block (the 1D 2D...GND block) that will start the logging. How would i code this in the interface?

Thanks for any help, and sorry if this is unclear! Not fluent i

When i use the run wizard to set my mains frequency to 60HZ and temperature units to Fahrenheit , I continue to the end where i click on submit. When i collect my data it is in Celsius and when i check logger regional settings i see 50HZ and Celsius. I am using a DT85 with v9.22 firmware.
