Hi, i wqnted to copy some files onto the usb from a DT82I but it reads the usb too long. It is an empty one, and i am not sure what is happening. I want to mention that i have a schedule running and i am not sure if that influences. I was doing the followong logon, then run the schedule, then logoff and then i was able tonread the usb faster, but when i copyed the job, there were no recordings
Hi, i need to use 4 analogs , and make a chart with data while these analogs are changing values. So, i learned how to read these analog values instantly, but when trying to record them and put them in a chart i have lots of issues. Can you please give me some hint on what i need to code for the thing to work? I have some errors i think of syntax but u tried different things and still not
We finally release the new version of dEX which is a PC based application and free from flash player.
dEX® 2.0 is a simplified yet powerful software that allows you to configure and program your DT80 series data loggers. This configuration-based software allows you to configure the hardware, visualisation data and also debug your application on all DT80 series of loggers (includi
I try to write a script that will read the sensors on my Datataker DT85G but I run in to problems. I try to use the command server and connect to the local ip and can see all the commands but when sending commands I get problem.
It works fine is I logg into the Datataker through the web interface. Then I can send commands and receive results. However, if I'm not logged in through the web
Hi, I am a newbie in using the data taker. I was trying to create a schedule to read a DI every second for 1 minute. Then i deleted this schedule and i wanted to create another one..but this time any typr of codefor schedule i try to run is giving me this errror Cannot log: job untitled has existing data/alarms I have used deld..to delete all the data but it says there is no job
I have to use modbus function 0x03 to read values from a probe. But ist seems that the DT80 only supports 0x04. I was able to send the command manually via serial but when I try to read the answer which I can log in a terminal all CV variables stay empty. I tried %1b[CVx] and %1c[CVx] as well but no success. The exact command I used to read the values from serial port is 1SERIAL("%*3b
dataTaker does not have automatic detection on daylight saving however it is possible to introduce time manipulation through the code.
This is the code Jairus Pascoe from Metro Train which address daylight saving in Melbourne. Daylight saving in Melbourne start on 2 am the first Sunday of October and end on 2 am the first Sunday of April.
Current measurement using internal shunt resistor may prove difficult to achieve because there is measurement relay which separate output circuit of the sensor with shunt resistor. Using a default measurement delay of 10 ms may not be enough for some sensor.
Thus the only solution is increasing measurement delay, however some sensor may need a couple second to establish stable current
We need a simple way to totalizer a slow pulse from water meters and the same time reset counter each datalogging. Reset is easy using dEX with “Reset Counter”, but ”doesn’t exist the “Totalizer Counter for ever”
Our distributor in Chile sent us a request to implement PenMan-Montieth formula for evapotranspiration measurement using dataTaker. This formula requires several parameters that need to be calculated first from 10 measurements:
temperature (average, maximum and minimum)
relative humidity (average, maximum and minimum)
wind speed average
altitude from sea level
We manage to
This time I will explain about some possible causes of error related modem messages:
SESSION: Failed [Network check] - will retry This error is related to connection testing by pinging to dataTaker website after the internal modem established a data connection. If the pinging is unsuccessful, data connection will be dropped. There are 2 possible issues:
I have a DT85 with 1 CEM20 connected to channel 1. They are both collecting strain gauge data. I have the strain gauge wires going to the DT85 and CEM20 grounded via the grounding screw on the case of the DT85.
All the DT85 channels are looking good in terms of data and noise but the CEM20 ones are all showing the same noise levels. I do have a channel in each unit to compensate for n
This topic will cover programming method to read raw data of precipitation spectrum from a disdrometer: https://www.ott.com/en-us/products/meteorological-sensors-26/ott-parsivel2-laser-weather-sensor-2392/.
Precipitation spectrum is useful to classify the type of precipitation based on the size of the droplet (diameter equivalent) and its velocity. Each properties of droplet (size and velocit
10 kohms range is one of dataTaker series 3 measurement limitation, however there is method to pass this limit without even using a parallel resistor depicted on R6 wiring configuration of resistance measurement (DT8x User Manual).
Resistance measurement is obtained by excite a resistance device with current source, then measure the voltage across. Within dataTaker this voltage reading will g
This topic will show how to create UNIX timestamp as alarms text.
'11CV – ten thousands part of number of days since 1 January 1970 expressed in second
'12CV – thousands and hundreds part os number of days since 1 January 1970 expressed in second
'13CV – tens and ones part of number of days since 1 January 1970 expressed in second
'14CV – initial 4 digits of UNIX time
This topic is about reading MODBUS function 23 which is not possible using direct syntax of dataTaker. This is related to Mastervolt Mass battery charger : https://www.mastervolt.com/products/mass-24v/mass-24-25-2-230v/
There are several requirement prior of MODBUS reading:
you will need to do the reading using SERIAL syntax rather than MODBUS syntax
you will need to know MODBUS polling s
