I making a voltage read between 5* and 5#, defining the channel as HV. However, the dt80 read is not the same as measured with a manual multimeter.
I should had something around 12.59V and dt is showing 11,6V.

I'm not used to deal with HV channels, so what I'm missing here?

I've tried to check if some attenuation option is enabled but i'm not getting how to overcome this...

I've recently installed two new instruments for rain and wind measurements (HSC channels).

However, sometimes the logger skips or misses a step (1s acquisition rate). why is this happening? - file with data example. I've identified in yellow (temp diff) some of the problems.

The logger has other schedules in operation.

I tried to upgrade the firmware of a DT80-3 from 9.08 to 9.18 using a USB flash device but it wasn't upgraded and did show an error (DT8x Bootstrap, file error). I I've used the files for new firmware before and it did work. Does anyone know what could be the problem?

Hi all,
I've been using DeTransfer for a while now, and I use DDE commands to send data to another software package that does all of my logic and fancy GUI stuff.

However I've noticed something funny on of my systems - after a while of acquiring data, slowly but surely, the DDE data gets corrupted. The channel names (and DDE modifiers) somehow leak into the data. So say I want to read the

Hi there,

I'm using two loggers, one DT80M Series 3 and one Series 4.

I know that I can switch the isolated 5V power output on using the command:


However, this setting is not persistent and vanishes after a logger looses power (and the backup battery is down). Is there a way to switch 5V power on using one of the profile parameter settings, making it thus persistent?

I've been communicating with my DT80 using a little python code, configuring a serial port and sending string commands to the datataker. I've been successful using the USB cord that came with the machine, however when I use an RS-232 to usb cord, the DT80 doesn't seem to receive (or send) any information.

How can I set up the DT80 for serial communication with an RS-232?

I have DT80 series3 software version 9.10.
I will start a schedule when 4 or 5 CV's changes from 0 to 1 or 1 to 0
Hoe can I configure this when I programming in dEX.
I can only configure 1CV (Advanced triggering)
In program language it must be RB1..9+CV ?

Thanks for help

An ungrounded differential signal source can float outside the common mode range of the logger inputs. Possible ways to prevent this are:

grounding one of the signal lines at the logger
grounding one of the signal lines at the logger through a moderate value resistor, eg. 10k (
grounding both of the signal lines through high value resistors, eg. 100k,

I've tried this using the USB cable and command window.

On the DT80 can the default file name of the FTP transmission ( sequence #_ time and date) be modified? I want to change the sequence # or add a Station # and keep the date and time.

Thank you

dataTaker is a powerful and versatile device and it's able to get data from almost any sensor type. This comes handy when designing new serial sensors with custom protocols as you can use existing well proven hardware for actual data acquisition. However the serial channel doesn't support any kind of data packet integrity check. It would be great to get computed CRC16 or even CRC32 from

I have 6 loggers in monitoring equipment and sending data to a central FTP server every 15 minuets and every 24 hours.
The problem i have is that they all ftp their data correctly for several days, or sometimes weeks and then the data file appears empty after a certain time

An example of a good file is

I have a weatherstation with ESAU datastring. Every 10 minutes the input string to the DT will be 255 caracters longer (new weather data appended).
Now I try to discard the new inputstring till the following formatstring I can see "YYMMDD HHMM".

Is it possible to generate the YYMMDD via 20SV, 21SV and SV22-2000, and the time via 1ST and 2ST as one search string?

Hi all, I hope that someone could help me to confirm this:

We are about to obtain some sensors that have a very small current signal as output, the larger could be about 30mA (around 3V considering multiplier), and the smaller could be even below 1 millivolt (even using a voltage amplifier).

Considering the information given in page 19 of the Manual (UM-0085-B8-DT8x Users Manual):
