|Do I need a current calibration for using the free measurement mode on a DGA 2500 exhaust analyser?
Recently picked one up for home use, but foolishly didn't try it out until after the existing calibration had expired!
It seems to go through all the right motions, just no values appear in the measurement boxes on the screen.
