I have a GRT EIS 6000 and Hx EFIS and the CHTs are reading too high. The CHT first goes into the EIS and then out to the EFIS. At room temperature they are equal to a calibrated temp meter but at 212 degrees they read 35 degrees too high. At 400 degrees its too high by about 75 degrees. And goes up from there. Pretty much in a straight line. Anyway to calibrate this?
I haven't been able to reach GRT at this point. Thanks!! Dan

Me too!

There is no calibration adjustment, I had one 75 F low when all four were dipped in boiling water, the others were about as close as you can expect. I called GRT and they sent me a new one no charge. I check them at CI now.

Thanks!
I've got a call out to GRT but they don't seem to be answering their phones today.
