Missing Entries. Strange Outputs

Hi, I have had some missing data in certain sections of my logging. Some sensors have not recorded a value at certain time points, other times all sensors have a blank at a time point. Additionally, it looks likes one of my sensors was reading as 0 pressure for around 4 hours. Not sure if this is ha...

Formula Not Working

Hi All, I have obtained calibration slope of pressure sensors with a calibrated pressure input and have recorded the voltage against this to plot a chart, obtain the Y equation with a view to input this into the software to convert V to pressure. When i apply the equation e.g. - y(pressure) = -0.144...

Time and Date Stamp Incorrect

Good afternoon, I'm looking for some advice with PICOLog and digital pressure sensors. I have a 1216 with 8 channels monitoring pressure. I want the data time stamped and recording interval of 30 minutes. i have the sensors reading every 30 seconds, for the graph, but the table and datalogging is 30...

Re: Datalogging 8 Channel

Hi Wooster, As I mentioned, just getting some shielded, single core cable, should solve the problem. However, just so that we are on the same page, could you post Picolog data files showing the 'bouncing' you mentioned, at different sample rates, and also post an image (or images) of your setup. Re...

Re: Datalogging 8 Channel

Hi gerry, Thanks for the reply. Apologies that i havent explained very well. I havent shielded the sensors - only grounded. I havent got a shielding wire for the pressure sensor reading cable, and have only used a 0.22mm wire. The values i am getting are jumping around a little bit, which i assume i...

Pi4 7" screen resize

Hi All,

I am looking for some advice with PICOLog on the Pi 4. I have connected to official 7" screen but the PicoLog window is far too big. Is there a fix / solution someone might be able to assist with?

Thanks all!

Datalogging 8 Channel

Good afternoon all, I am looking for some advice. I have bought a PICOLog 1216 to capture 8 pressure sensors at the same time. I have built a box and mounted all inside the box using terminal blocks to split 24v supply to each sensor and ground. The sensors have a shielding but to connect between th...
