Is it possible to use PH/Redox Sensor BNC port for other purposes?

Dear Members I haven't any plan to use the PH/Redox Sensor BNC port (Channel 5) so I am considering using the port for other measurements, if possible. From the User Guide, it is not clear about the specification of the port (for example is it measuring voltage, current or resistance. Could I use th...

Calibration of NTC based temperature sensor (Thermistor) with DrDAQ

I have successfully calibrated a low-cost yet high-accuracy thermistor (103AT, Semitech) by using the DrDAQ and temperature sensors (DD100). Doing fun and trying to understand how hard scientific experiments are conducted. Please see the whole calibration process in this video: https://youtu.be/JpD8...

Re: Problem with the data table

I have exactly the same experiences with the latest Picolog (and USB DrDaq). As a workaround, in the table setting DON'T tick (enable) any channel which is derived by the mathematical channel. Suddenly all measured data appeared. This is strange and I think this is a bug in the Picolog. This is also...

External sensor auto-detect resistor

I have made my own sensors for LPT DrDAQ and I want to connect them to the new USB DrDAQ. With the latest PicoLog (6.2.4) there is no .DDS file (for declaring the auto-detect resistor) stated in the DrDaq manual (revision/version 6) although it is stated in the revision/version 5. I managed to conve...

Older Picolog version as stated in DrDaq Manual Version 5

A long time ago I purchased the DrDaq LPT version and used the then old PicoLog software. Yesterday I bought a USB version of DrDaq and installed the latest Picolog software (6.2.4). It is OK but I would like to use the older version which is cited in the DrDaq Manual Version 5 since this older vers...

Near Simultaneous Output and Reading

I use VB for collecting and displaying the measurement results from my DrDaq. The following may be a stupid question. Using the provided pico DLL, could I send a 1 ms pulse to the digital output while making a fast mode measurement (i.e. simultaneous output and reading) to see the response of a circ...

Controlling DrDaq using LabView Version 5

Is possible to control DrDaq using LabView version 5.0 ? If yes where I can find the driver ?
Thanks in advance !

How to write Fortran Code for controlling DrDaq

I am now considering to interface the existing control programs written in Fortran 77 and Fortran 90 (with Visual Fortran Version 6) to DrDaq. So far as I know, Visual Fortran and Visual C or C++ can communicate well (i.e. mixed language programming). Since the driver for DrDaq was written probably ...
