Need help re new thermocouple

Re: Need help re new thermocouple

My new thermocouple from jaycar is not working with my DIY roast controller. The problem seems to be that the probe is connected electrically to the connectors and as soon as I insert it into my popper I cant get any readings as the connectors become earthed.

This points more to the likelihood that theres a fault with your Popper or even your Domestic Installation (your house wiring). Id get a licensed sparky to check out the Popper and if this checks out OK, then you need to have the House checked out.

Re: Need help re new thermocouple

I dont get any resistance showing on my brand new CS multimeter and probes, on the "ohm" setting.

Also, Ive been using t/cs from Jaycar and DSE for ages and never had that problem, including when I was using a popper.

:-/ Can anyone help with this?

All I need someone to do is set a multimeter to the continuity setting then put one probe on the thermocouple tip and the other on either connector.

Anyway, Im after a new thermocouple where the probe is electrically isolated from the connectors.

Can someone test the two that are available in beanbay?

Does anyone have a pic of this one (beanbay is missing a pic)? Is it yellow?
