Serbus Elvtars Ur! Lived on Klauzal Ter in Pest for a while--prior lifetime--early 70's. LOTS of good memories! Transverse error is a tough one. It comes from not mounting the die exactly square on the substrate--do the math and you will see that even a degree can make a real difference! Most people I know that are really concerned spend the time with a multi-axis table and calibrate under all possible conditions, then set up their data correction algorithms to take out the cross axis stuff. Alternative is to buy the die and mount them yourselves--but that introduces other problems best not dealt with at the hobby level. I have heard that Crossbow (the company, no url, etc) takes three of the ICS sensors, mounts them in a triax configuration with a PIC, and an ADC and DAC, and actually outputs a corrected analog signal--all for around $500. THIS IS RUMOR--I have not confirmed with crossbow yet. If so, it is on good deal! 3052 is a new product--I was faxed a copy of the pre-release data sheet. Try calling ICS directly.
