The behavior has been normal since I made the ufinished grounding. Hi Jan. Your solution with grounding is correct. I have had the same experience with several USB TC-08´s and they are very sensitive to even small voltage differences between input terminals and computer chassis/ground. Even isolate...
I've written about this issue several times in this forum, but got the answer that TC-08USB was a 'value for money' converter, and there were no plans to re-design it. The CJ compensating layout has a very poor thermal design. The CJC thermistor is placed in air right in the middle between the 8 inp...
Hitesh. Just briefly checked it out, and it seems to work OK and average between loggings as expected. Only 'nag' so far is that in the opening screen, and in ' Help > ' About ', the copyright statement is not up to date (year). It says Copyright 1997 - 2011 (should be 2012) :wink: Unfortunately som...
This is what I did (in XP and older systems). There may be other ways. - Make your settings.pls read only with the File Explorer. - Right click settings.pls and choose "Open With". - Select "C:\Program Files\... \ PLW.exe - Check "Always use this program to open..." (Or what it is called in the Engl...
My colleague has found the cause of the issue and corrected it. The software build should be released sometime next week and will be available from http://www.picotech.com/software.html - it should be numbered after R5.22.2 which is the current stable release and contains some other fixes. Regards,...
Hi Ole, My colleague has found the cause of the issue and corrected it.

Hi Ole, Could I ask which device(s) you are using please? I can't say at this moment in time how long it will take to resolve, but I'll provide an update when I've heard more. Thanks, Hi Hitesh. As I have written earlier, I've seen this issue from the earliest Windows versions of PicoLog and as I h...
There is a bug in the Picolog program that causes the averaging over the sampling period to revert to spot value at the end of the period if 'calculated parameters' are also set. Therefore I must request the Pico people to solve the problem and release an updated version af PicoLog, as I have to us...
The problem consists of PicoLog refusing to store the average value of the readings taken during the sample period (set to 1 minute), with the 'number of readings' set to 'as many as possible'. I find that it is always storing the spot value at the end of the minute, which is no good for my applica...
Ad.1: Yes thermocouples can be extended, but you have to use a 'compensating' cable, i.e. typically multicore cable made from the same metal alloy as the thermocouple itself, but normally not so pure and therefore cheaper. You also have to connect via "compensation" plugs and sockets, again made fro...
Hi In another forum on this board, 'Hitesh' wrote the other day: "PicoLog is unlikely to be developed further as PicoScope6's logging capabilities are likely to be developed further." We are (I think) a lot of users that use the more 'slowly' loggers (TC-08, ADC 20/24 etc), and uses the PicoLog SW. ...
If I want to use two channels with no CJ. I am limited to a maximum sampling rate of what……….? You cannot measure temperatures with a thermocouple without a Cold Junction compensation. That is a fundamental of thermocouple theory, as you actually measures a voltage difference betveen at least two T...
Hi, Can you offer any guidelines on programmatically detecting open and shorted thermocouples? A thermocouple is a short! :shock: If it is short somewhere else than at the measuring point, it just measure the temperature at the short ( or maybe a temperature between the short and the real measuring...
That is most likely because you change the TC plug temperature by touching it with your fingers and/or by generating heat by moving the plug in and out of the connector. Where the TC plug enters the TC-08 interface, there are 2 thermocouple junctions, the + wire connecting to the copper or nickel co...
