Temperature gauge calibration

[Pies]

Anybody know how to recalibrate a gauge on a RV8 my car runs at a steady 83 deg but the gauge reads 95 deg.

I've fitted a new sender but it now reads 100 deg

so anbody any ideas

Try contacted resident David Beer, He sent me a an ajustable Resister(i think its a resitor) that pluged straight on the temp sender and wire so you can adjust with a small screwdriver to get the guage the same as engine temp REAL.

Cheers how do i contact him Simon

How do you check the REAL engine temp?

I have access to a infrared reader and temp sensing strips but never really determined the best to take said measurement..

Infrared is not accurate enough (usually they are +/-2C accuracy - but in real life use, can be 3 to 4C out from true temp.
Best to use a contact digital thermometer, not sure what your temperature sensing strips are - but they can give accuracy to about 1C depending on their specification.

If you don't want the expense of buying a thermometer (which I can understand), then the infrared is probably your best/easiest to use bet - just get it in close to the heat source and take several readings to be sure - some meters need to aclimatise to the ambient temperature before they are any way near accurate.

Hope that helps?????

PS. Yes, sad I know, but I do sell high accuracy digital thermometers for a living!

Cheers, we have a variety of thermocouples/sensors at work, but I was thinking on the best place place to stick it....

I suppose stuffed in through the top hose (between clamp/hose and waterneck?)

I guees the best place to shove it, would be where the ECU sensor is, on top of the head pointing upwards with a posh two pin sealed socket on it. You can get to the screw thread for the test. I use the sender next to it for my temp guage, so do others. Pies, do you have this spare sender ?

Just seen this

Cheers for the resistor David much Appreciated

Not sure if i have the sender or not, to calibrate the gauge i removed the sender from the car and placed in a calibrated heat source (0.01 error)

Seemed the easiest way
