I'm measuring wind direction every second using a 360 degree pot (actually 0-355 as there is a 5 deg dead band) and am using the low current 200 uA excitation option in order to extract the variable voltage.

I don't think I can use the resistance method because of the dead zone of the pot. My first question is how long will the mechanical relay that is actuated every second last?

Hi,

A few questions from a newbie regarding wind speed measurement. I have an ac generator wind sensor (RM Young) which gives only a few mV at low speed rising to several volts at high speed.

The frequency is the component read and I am seeing inconsistent results from a steady wind stream supplying a test bench sensor at around 4 knots. I see very steady results when connected to a com

Dear Sir,

We have some question about to operate DT80:

About the arithmetic operation. except for the expressions mentioned in the manuals, like some functions ABS(), Sn()... may we realize some more complex functions, for example: co variance?


About communications. we need some more flexible ways. We want some programmable module functions about RS232/485 communications. For exam

Dear sir,

How many channel entries does the DT80 allow? I can't find any information in the manual. Appreciates for your answer.

Best regards,

Hello,

I'm trying to connect to the DT80 via GPRS using two Wavecom Fastrack M1306B modems. I can dial out via Delogger or Detransfer to a mobile phone but can't seem to connect to the logger. Has anyone been able to configure these modems to work with the DT80?

I want to use the relay to connect a serial data line to the DT80 at the start of a schedule and switch it off at the end of the schedule eg.: 1RELAY=1 1SERIAL(...,W) 1RELAY=0.

The purpose is to prevent waking up the DT80 by serial data between the scans every 5 minute. It seems that the W channel option (no logging) is not allowed for 1RELAY, so how do I prevent the 2 1RELAY channels in the

I'm getting the ATTN light flicker & the following message on the DT80 when I apply the needed power. "DT80 RESTARTED - POWER LOSS".

Any help would be appreciated.
Thank you.

Hi Roger,

Have you used the DT80 with any GPS instruments yet? If so were you able to extract the Time stamp for clock correction on the logger. I know the loggers clock is already very accurate but it's more to synchronize a network that may have been set up using different laptops with different times set on them.

Thanks,
Chris

I am sorry if the question appears too newbie... With MODBUS/ RS485 compliance, does it mean that I can configure the following...

Scenario:
SENSORS 3 x load cell with MODBUS re-transmitter 4 x displacement transducer, direct connection 1 x measurement system with serial output, re-transmitted via MODBUS.

Basically, these are my current problems: Load cells are connected to a digita

One of our client is facing problem with DT80. The application is temperature monitoring in Concrete. The client is using K type thermocouple for monitoring temperature.

TEST is showing PASS result but when the thermocouple is connected, the error message is shown on display REF ERROR. What could be the problem?

The DT80 is a great logger. I have a few "wouldn't it be nice if.." ideas. It would be nice if Delogger or a reduced version of it could run as an application ON the DT80.

Then by simply attaching to it, the user would be able to grab logged files (replay or CSV) logged that were created as Delogger ran in the background. This would allow unattended but programmed downloads, dial outs, FTP t

Hi,

I'm trying to connect an ADAM's module via the serial sensor channel and am failing. I get a time out error 20 state. Any suggestions?

Dear Sir,

Please recommend me further information regarding how to suitably apply DT80 and Delogger4 software as the following questions:

How can we use DBD file to be stored in USB memory stick? The configuration of DBD file will be stored in USB memory stick as following: SN081878--> JOBS-->JOB1--> A--> "My Job name"-->DBD file.
What is the application of DBD file?

What exactly does this mean? Is there a function that you can call on DT80 to through a relay and let power out that port? It says V=up to 30. So it must get its supply from external power source?, if that is disconnected does it power off internal 6V batt?

Thanks

Is there anyway to extend the input ports. So that there is more like 20SE and 10DF inputs. I really like the memory stick capabilities and analog input connectors but I need more inputs.

Hi,

Can the internal battery of DT80 be replaced with 12V? I need to run 12V relays and cannot lose them when power goes out (briefly). I do not want to have to connect 12V battery externally, and have internal 6V on DT80.

Good morning,

I want to instruct the DT80 to output a modem a command string with single quotes in "actionText". I am able to send a command to the modem. My request is: how do I get/ read the modem answer?

How to connect quarter bridge strain gauge connection and take measurements in uE? do you have video?

I have connected a strain gauge to channel 4. in configuration, I have added current bridge, selected appropriate current bridge and channel. After downloading the data I have got a value of 500,930.5. this is a huge value.

If I press the strain gauge I can see the variations however, the

We have been working with DT's for a long time, but this is our first time working with a MODBUS device and need some help.
Usually when we write schedules, we do a polling schedule at 15 seconds where we read all our sensors and do calculations, and a reporting schedule at 15 minutes that reports sums/averages as appropriate. (EX: RA15S, RB15M)

The issue we are having is that in all the l

Hello,

I was wondering it is possible to use DT85 to control a solid state relay ( e.g. control voltage 24V, 13mA) through dEX web interface? If possible could you please share with me how to set a job on dEX or point me to a link. Thank you very much.

With regards
