Calibrate engine probes?

Well Known Member
Any advice from the experts on the easiest/best way to calibrate the engine probes? EGT, CHT, Oil temp, Oil Pressure, Manifold pressure?
 
If you want to calibrate them, it will not be the probes you calibrate, but the instrument / EFIS end.. in turn depending on what type you have, and if calibration is possible.

If you want to check them for accuracy, then the boiling water test works well?
 
Thanks for the advice

I have a GRT EIS with two Hx screens. I don't know if there is a way to calibrate them, but it would be nice to know if they are accurate
 
Like Andy said, boiling water works as a check point for temps. Ambient temps are also a check point.
Regulated air works for pressure indications.
Barometric readings for manifold pressure. (corrected for altitude)
