hello Hans, welcome to FADU.
I use a Durst M670 with Durst VC dichroic head (up to 6x7). I have the RH StopClock and the Zonemaster and yes, it took me SOME time to calibrate for just Ilford MG IV RC. In fact my findings differed from those included in the RH manual, not a lot but sufficiently to make a visible difference.
Although the calibration seems a bit tricky, esp. the first time, it's probably worth the while for what you learn about contrast, exposure and your paper's reactions.
I've just got some MG IV RC Warm Tone - have to check how it reacts.
Peter
