Hi,
Could you please help me in connecting a 18-33vdc / 24 vac differential pressure transducer (3 wire) to DT 800?
The out put signal would be 0-10v.
I am a new user of datalogger, without knowing the analog input signal range (max 13v) have ordered the differential pressure transducer and i am desperate as i am reaching my project deadline.
Thanks,
Gowthm.
Hello.
This is my first post in the new forum. The question is that sometimes the datataker leds stop flashing and the Ethernet connection with the computer breaks. I thought that it could be a power failure, but I measured power voltage and it is correct.
The datataker is only externally powered (internal battery is disconnected), so I don't know if this is a sleep mode. After some tim
G'day Team,
Hope you can give me a quick pointer.
I have a serial scale sensor sending me back a weight in format "ST,GS 2.450kg"
So I am using the serial expression builder in an attempt to get the 2.45 out.
1SERIAL(RS232,"\eST,GS%f[5CV]kg")
Works like a charm getting me 2.5 (seems to round the decimal part up)
So I am trying a formatted float

Hi,
In the DT800 Manual, you suggest:
"4-Wire BGV Inputs
Use voltage-excited bridge (BGV) configurations only when the bridge is close to the DT800
(BGI configurations are usually preferred)."
Can you say what it is you clarify as "close to the DT800" and is there any way to compensate for the extra resistance in the wire if its say 25 meters from bridge to DataTaker?
Cheers
Hi Team,
I have a series 1 DT800 (i think, has no USB port), is there any way to update the firmware to that of the series 2 so to be able to use the DEX interface?
I cant afford a new DT800 at this stage but would love to have the DEX system.
Cheers

Hi everybody,
I am recently using Datataker DT800 I am using Delogger software to get data like temperature, voltage, ect...
It shows the data on Form2.dlf window on Delogger but I don't how to keep or export it to an excel file.
Could you help me please?
Thank you very much.
Hello,
I am currently troubleshooting a DT800 with multiple analog and digital sensors connected to it to monitor a residence. The analog sensors in question are several thermocouples and a RH sensor.
The issue we have is that the datalogger will report unreasonably high 15 min. data for several of the sensors simultaneously and then go back after an hour or so (sometimes randomly) to repo

On page 173 of our manual I see the Shared-Terminal 3 wire resistance inputs on one channel (the lower left illustration) does not show that the wires between the resistance element and the common point need to be short.
However, based on the illustration to the right of it, I think these wires should be kept short and this is just an omission. Should these wires be marked with an "S" as the

Hi guys,
I'm using a DT800 with delogger5 to take measurements from 16 thermocouples and using the digital output to control a solid-state relay.
The problem is that when I unload the data after logging for 5s say at 1s intervals I typically have twice as many entries as expected and the timestamp for the entries does not make sense. It appears to have logged data for longer than I would h

Hi
can you advise how i might program the DT800 to acheive the following.
i have 2 linear sensors connected to the logger measuring movement and i want the logger to control a ram which moves from 0 to 2mm. The control of the ram will be via digital out from the logger and i want the logger to operate the ram whereby the ram moves to 2mm then returns to 0 mm in a cycle which runs for 200 t

Hi. I'm having trouble communicating with my DT800 s1 via Ethernet.
I have managed to connect via serial and I've ran through the setup procedure but it does not appear as a network location.

dear Sir,
one of customers is using dt800 for resistance measurement.
recently we are facing the following problem;
measured resistance values are lower than actual e.g. 260 Ohm is measured while actual is 350 Ohm.

To all.
I have a three wire pressure transducer.
When connected to the DT800 it courses a very very high pitch tone then the power supply trips out and the continues cycle in this state. I have disconnected it in case of damaging the DT800. Could anyone explain why it is doing this?
Many thanks.

Good morning all.
I would like to ask, if it is possible to switch 5 solenoids on using the DT800.
I would want these solenoids to be started with a button on a mimic and run as:-
On for 1-20 seconds.
Off for the reaming time in a 20, 30 & 60 second periods.
Repeat for 10 -50 times.
This would be for an individual solenoid or multiples up to 5. If more than 1 solenoid was to be

Could you just confirm that Delogger 5 & a DT800 are not compatible with windows 7 please? I found a post some time ago confirming this but can't find it now.

Hi,
Does anyone know of a piece of equipment that can read an appliances power consumption and then log it using our DT800?
Many thanks.

Hi all,
First Question,
I would like to ask if there is a manual I could down load based on the program builder and not on text file programing. Converting what the text line is in the manual to the program builder is a bit tricky!!
Ok next question,

Hi guys,
I'm using i-checker devices like these:
http://www.aros-solar.com/es/sistemas-de-monitorizacion/ichecker/
These measure the current passing through a conductor but I need a device that takes the data stream.
Could I connect to Datataker Mider and the current through streamings?
Or if there is any other option to measure the current of the i-checker with Datataker DT 800

I just read through all my sensor and DT800 information. I am still confused as to the setup of the button sensor to the DeLogger software and what code I need, if any. Please help! The button sensor is DME and comes with the button sensor, and a button sensor cable that can be connected to the DT800 via the AUX input.

I'm using delogger5 in Windows XP mode via windows virtual PC on a windows 7 PC.
If i leave the network connection open overnight it is lost and i have to power off and on the datalogger to reconnect.
When i reopen my project and try to send information to the connection i get a status check error with the message window " the link to the datataker appears to have been lost"

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
