Hello,
I have a humidity sensor with me but I have problems with connection, both to the channel and also the Delogger. I have connected the Yellow (Temperature) to the +, the Brown (Humidity) to the - and the red to the # terminals, which I am not sure am I doing the correct thing.
The power supply that I am using gives 12V of output. At the Delogger, I choose 10V for 'sensor power sup
I have a DT800 which was not used for over a year. Switching it on today using the internal battery everything seemed fine, the IP settings were still set and I was able to access its web front-end via the Ethernet interface.
Thinking that it could probably do with charging I plugged in the DC power supply and all the lights and display instantly went out. Now when I switch it on or do a (pa
Something seems inconsistent between the statistical channel option that calculates standard deviation and the ones that give min and max.
DT800 occasionally delivers standard deviation values of 0 when the min and max values are not equal. This simple program causes most records to represent a sample of about 8 or 9 readings but rarely as little as 2 or 3.
In some of these rare cases t
Hey wassup.
I'm trying to measure frequency from a flow meters. So far I'm just trying to measure the freq from a function generator, I select a square wave of around 400 Hz and +-10V of amplitude and I connect it to channel 3.
I type "RA1s 3F" and the only result I get is -99999.9. I tried changing the threshold as indicated in the manual but I always the that same wrong result. How co
Hi,
I am a complete beginner. I have a flow meter with a 5 Vdc supply requirement, a 0 Vdc return and a signal output. The signal is a square wave 5 volt peak. There are 500 pulses per litre.
For the 5 Vdc power supply I am using sp terminal. set to 5 Volt in p47. For the 0 volts I using the sr terminal. For the signal I am using the + terminal on analog channel 2 for example.
In p
My DT800 stopped recording after a few hours and was flickering all its LEDs in a repeating pattern. I think it was consistent with the forum posting "All five LEDs flash", which resolved to a repeating reset due to memory card problems.
I also noticed are that the amount the DT800 4SV channel reports written to the card is -521823.0 (yes, negative). This all seems to point to an incompatibl
I am having problems as well with my DT800 and the internal battery supply. After Fully Charging the Battery the DT800 will only last for around 4-5 hours before voltage drops to below 9.5 V and the system goes to sleep.
The only program running is checking the internal battery voltage and Current once every 1 minute. Full Charge on the Battery reads 13.97V It appears to be drawing around 69
Hi Roger,
We have purchased a DT800 dataTaker and are experiencing difficulty setting up the Ethernet communications on the device. I have followed the Ethernet comm setup procedure in the DT800 manual but fail to see the green led flashing on the Ethernet port of the DT800.
After a triple push reset we notice a solid amber LED light up on Ethernet port. If the Ethernet cable is unplugg
Hello!
We're trying to get this laptop to work with our DT800, and it comes back with the above error. We're trying to connect it wireless, it works on another laptop but I can't figure out why this one laptop doesn't work.
There is no firewall set, and I don't think I have any anti-virus software loaded on it to prevent a connection. Wireless system is working--can connect to the inter
Hi Roger!
Look...in DT500 exist one command for settling period that allows the input signal to stabilize before is measured, that we send the command 7SV.
How can I do this kind of procedure with the DT800? Is that possible? Thanks.
Hi.
I've a doubt, can you help me? I'm using DT800 with 128 MB memory card and i can't save the program inside the memory card. There is anything that i can make to save not only data but the program inside the memory card too?
Thanks
I can't get connection to my DT800 using Ethernet. In profile I've set the static IP for logger gateway and so on (when that is done a message of resetting logger appears, and the logger resets).
I can ping the logger but when i connect via Ethernet. I don't remember the words but in the log i get a message like "connection was force rejected" or something. Just wondering what IP is set unde
Hi,
I'm having some problems with my DT800, because in the laboratory I worked and I made some tests with it and everything is fine.
"TEST" command said "PASS" and everything, no problems at all, but when I place it on a structure (a train bridge), that I'm monitoring, and I send the program, the DT800 shut down, death, all lights gone, and I can't connect it anymore, don't respond.
When I run the following burst schedule it doesn't trigger.
RA;BURST(2000,4000,LEVEL,50,0S) LOGONA GA
1VNC(S2,"Starting current",LEVEL>720,GL5V)
2VNC(S1,"Capacitor Voltage",GL5V)
If I remove the 2VNC line it works. What's going on? Do I need to specify a LEVEL in the 2 VNC line?
Thank you in advance.
Hi,
Long time no hear (or write)! I have a relay that I want to drive from Digital Channel 1, operated by an ALARM. Voltage level on the channel switches between 3.6 and 0v (approx).
Can I connect the relay coil directly between dig Ch 1 and Gnd? I am a bit confused reading the manual.
Hi,
I have two DT800's out in the field which are being used to log wind data at 5 Hz over a period of several weeks. Each logger is taking half of the measurements and the plan was to later combine the two data sets.
However, I have just being processing the first months worth of data and have found that there appears to be a significant time drift between the clocks of the two loggers
Hi,
I just about to consider DT800 in an industrial application where I need to sample several discrete inputs (24VDC) and analogue inputs (4-20mA).
The total number of I/O is 214 DI and 81 AI, and I just read many forums and DT8x manuals, but I'm not quite sure how to manage it. By using standard DT800 I would need 14 units, but I'm not sure if I'm able to put them all in the same Ethe

Hi,
First of all i do follow the upgrade FAQ and i can't find doing anything wrong. But makes the first upgrade step upgrading to 316v4b. I see the bootloader starts in details then it just get stuck and i see some strange letters.
The "OK" button is just grey marked, and the loading bar haven't even started. My first problem is I have version 2 update 10 and when I lo
Hi,
Our DT800 gives FAIL for:
Analog Pos Supply 1.1 (FAIL)
Analog Neg Supply 0.7 (FAIL)
Common Mode Rejection Ratio 0.0 (FAIL)

Additionally we cannot take any analog signal from any analog channel. There is no problem with digital channels. We have started to get these fail messages after making several measurements using a wireless torque meter which was ins
Can DT800 use channel expansion module (CEM)?
Hi,
After getting my capacitance strain gage multiplexer system working the mechanical engineers have now given me another test!
They would like to now add 14 resistance 1/2 bridge strain gages (one active one dummy for temp. compensation) and 5 thermocouples to the all ready active one thermocouple, one full bridge gage and 4..20mA current loop running on my DT800.
I don't believe
Hi. I am new in forum.
I made a LabView program that allows me to set the analog and digital outputs of the DT800. When I set the values with a control in the front panel there weren't problems but when I tried to program a PID controller to set the VO value after a while it stopped working out.
I founded in this forum and with the deTransfer that I was receiving the E55 error message.
Hi Roger, please help!
I am using DT800 in burst mode to read accelerometer data. Take excitation from 12V Serial Channel (have to, as need the other Sensor Supply to be 5 V, while the subject one needs min 8V). Output is connected as V to +/- connections.
The setup works fine with data values below 1000 mV. However, once the acceleration values exceed that level, the logged values go "
I have been trying with out much luck to get a alarm to give a digital output which i can use as a switch and later to feed into a XSMS modem.

Help please...
I'm trying to down load alarms. My DT800 is in a remote location with a GSM modem attached. when I dial into the logger I want to be able to down load the alarm to see what has been happening before driving out to site.

Hello, there!
Just to make sure you don't delete me from the Forum, here is another little question!!! I have an accelerometer connected to DT800 as a bridge. When displayed on CHART as a graph, the output shows 3 sec Heart Beat spikes (-ve). Is that normal?
Should this accel be connected as a Voltage i/p??? For info - The bridge Sense input is 10 V and looking at the cct of the accel,
Hello everyone,
I have DT800, the problem is: I connected with thermometers and thermocouples enmallado from an electric generator, q is also connected to the datataker Sr, and the earth electric andalusia Ch.
Both online and offline probe lands but the noise continues, I have many variations of temperature. no is constant, if someone can help me.
Thank you
Hi,
I have a DT800 connected to an Ethernet network from which i am viewing real time data with the mimic screen. I have to now set up a display room for visitors to view the data from the the mimic on screen.
I have placed a PC in the room with Delogger Pro running which displays the mimics on screen for viewing. What i wish to do is to protect the DT800 program from unauthorized chang
I have a DT800 permanent linked to my PC by RS232 cables (COM1). I use DeLOAD to periodically and automatically unload the logged data.
Now I improved the monitoring system and I connected to my PC an independent accelerometer (connected at COM2). I have access to stream data of the accelerometer in a LabVIEW program.
I would like to be able to change the sample rate of the DT (1 Hz to
G'day,
I am a new user and am experiencing difficulty in having the DT800 begin logging data at a specified time. Researching the forum suggested that I use something similar to the following:

ALARM1(T>15:11:00){[GA]}
ALARM2(T>15:13:00){[H]}
RA1S
1TK

The DT800 has no trouble in ending its logging at 15:13:00 however it begins to log as soon as I have se
