Hi, I am an Auto Electrician and Mechanic from New Zealand. I have been in the trade for 16 years since starting my Auto Electrical apprentiship working on cars, trucks, earthmoving equipment, boats etc. These days I stick to cars/light commercials. I have owned a 4 CH 4423 for around 3.5 years now and to be honest havn't spent any time on the forum up until the latest Beta release 6.9.9 with the waveform library. What a great addition. I will add my list of saved waveforms good and bad as I get time and look forward to spending more time on this forum!!
