Used today a TC08-USB together with a ADC011-USB.
Is it normal that the plastic casing becomes 43Â°C on the upper outside?
What is the influence of this on the measured values.
How it comes that the measured which were all around 20Â°C at a sudden rises all +/- 20 to 30 K?
When disconnecting one of the probes (T - TC) everything became +/- more normal. That probe was attached to a copper pipe.
Once the system running for some minutes, from the 8 connected TC's , 2 measured correct and 6 deviated seriously. One probe had to measure was around 100Â°C (almost boiling water in the pipe flowing) measured with and Pico registered +/- 50Â°C.
Another TC measured 45Â°C where the temperature was 58Â°C.
Everything was calibrated before twice: in crushed ice and in boiling water.
What can be the reason: a too hot casing perhaps?
For what can we use the cold junction? This is a measurement point somewhere in the casing I suppose.
The ADC was used to measure pressures between 6 an 30 bar. Those were registered correctly (Player) on the screen but how can I view them in a graph.
Afterward, I can see these values perfectly in the spreadsheet but I need a graph.
Is a combined graph possible with the temperatures? This is very important for our job (refrigeration) because there is always a relation between the measured pressures and temperatures.
