My dataTaker unit battery cannot fully charge. Every time I charge it to 100% and a arrow and NC will come out once I remove the direct power supply, the battery drop to 44% and keep dropping.

I used it to connect to 8 thermocouple wires and the data take every 10s. The battery can last for 2 hour and 15 mins approximately. Yet, sometimes it just last 1 hours. Some might explain to me? How c

I have problems with thermocouples type T on CEM20. The readings are erroneous and might change between -6.0 to 26.8 C between two scans (RA1M) even though that soil temperature is a stable substrate.

I have both tried single ended and differential connection, but neither of them works. I have checked/logged the 1REFT and it is stable. If I use an immediate scan, it seems that the measuremen

I would like to log the wind data of an ultrasonic wind sensor type Young 81000, using a DT80 series 2 (most recent firmware installed). The wind sensor has been programmed as follows:

it waits for the poll string "MA!"
it responds with the following string: " 0.52 2.7 -4.4 16.87 0" meaning: windspeed, azimuth, elevation, temperature, error code format: real[m/s], real[deg], real[m], real[d

Please advise before I burn the logger, is it possible to measure the voltage from a solar module using a DT80 directly without putting attenuator?

I'm looking at a voltage of 20-25 V from a module. The manual says one can measure up to 30V. I want to be sure. Please advise.

Good morning,

I have a problem with a DT80. I have a potentiometer and I want to measure the voltage drop across it. I have a external source with 9V connect to potentiometer.

I take the measurement between the positive terminal of the source and the central terminal of potentiometer. I would have to obtain a measure of 4,5V but the measure that I obtain in the datataker is 2V approxima

Hi,

We use a DT85 logger at various locations on a regular basis for logging temperature in retorts. The logger works fine, except in some location where power surges in the factory occured, we find a spike appears in our logged data.

The logger power supply is protected by a power surge protector. Is is possible that this is coming from the earth connection? Is there some way of stoppi

I recently purchased a DT80 series 2 datataker, the seller did the installations for me on my laptop. At first i managed to go through the part 1 training exercise.

Later i could not manage to go over the exercise. From the laptop the information i get is:

Warning: could not open serial port
Warning could not detect baud rate for serial part
How can i resolve this?

Thanks

I have a DT80 in a remote area with only GPRS network available. Through GPRS, I want to open the remote DT80 web page. I cannot install a GPRS static IP on the DT80 because it cost $500 in my country and none of my customers can afford it.

So I am thinking of using existing dynamic GPRS and DDNS (dyndns.com). However from my existing noobish GPRS understanding, this system will not work. Ha

Hi,

I have to use an analog channel as a digital one. Do I have to supply power with an external source? (may be a 12V or 24 VDC)

Thanks, Dumnall

P.S. Any news about Windows 7 vs DeLogger?

We got a wave sensor and it only outputs serial binary data. Can dt80 read serial binary data and decode it into decimal CV?

Messages from the WaveRadar REX consist of fixed length strings of binary values which are sent over a half-duplex link. Output messages will utilize the data link for approximately 20 ms every 250 ms and are repeated every 250 ms (4Hz).

Any message sent to the rad

Hi guys,

I have a DT80 onsite permanently connected via Ethernet to a laptop running Delogger 5. The laptop is just showing the chart and the trend of a process over a couple of hours.

Whenever I access DT80 via a dial in modem, Ethernet connection drops out, and it needs to be manually reconnected by me which requires a site visit. Is this a normal occurrence or am I missing something

I cant connect DT80 through USB using Delogger5, it say

warning : connection refused Find device check failure
warning : datataker not found on connection
I had set what ever it told install driver... select the correct port but it fail, can someone help me pls thanks

*I am using Windows 7 64 bit.

Hi,

We have a number of DT80's in the field, the people that previously setup DT80's are no longer available. Is there a way to automate the collection of the running code (not the data) from the DT80's so I can get the field crews to recover the code?

Thanks,

Hello,

I am trying to take some measurements with some equipment that require a voltage input, and am having some trouble setting this up correctly with DT85 series 2.

According to what I have read, I thought I could do this by using the external input location. I have a regulated 10V source plugged into the External plug. and set up a channel for a load cell and configured with "E" for

I'm currently working on a 4 channels DT80 that is reading too low on the 10 ohm range. Is there a layout of the 4 internal variable resistors available? I'd prefer to not have to do the trial and error method, I haven't found anything in the available manuals.

Hi folks.

At the moment I am getting a signal back from my turbine meter into DT80 using a hall effect sensor and the high speed counter but would really like to do it with a magnetic pickup. My pickup outputs around about 50mV.

Is it possible to bring the magnetic pickup into DT80, read it as a frequency and then work out both a total volume and a flow rate? I have gotten both of these

Hello,

I am using a DT80 to sample an ultrasonic anemometer (Gill Instruments WindMasterPro) at 10 Hz, testing using DeLogger v5. I've also tested the serial connection using DeTransfer, after reading this forum - seems to be working fine.

I'm finding that I get a few seconds of measurements received at full rate (10 Hz). Then I get an error signal: 'serial sensor scan error at control

Hi all,

I have a DT80 inquiry for monitoring PN systems and was wondering is there an examples of this done within the applications notes.

Hi,

I tried this on script; s1=0,100,0,1"m" where my sensor output should in range 0-1v, but why i got -ve value on "m"? I thought the lowest it can be is 0m. How to only return minimum value is 0?

Hi,

I am programming DT85 series 2 dataTaker using DeLogger 5. My purpose is to log the change of state of some 80 inputs.I use CEM20 along with DT85 and use analog state inputs.

I don't need a continuous log, I only need logging when the inputs state changes.I use the alarms on all the channels, assign alarm numbers and set point 1 with conditional test as greater than or equal to set p
