Hi All
I'm not sure if I should have posted this in the test equipment scores thread or if its worthy of a post of it's own. I live in Australia so by Oz standards of second hand test gear I think it's a score at least as it has only cost me AU$1050 including postage from the other side of the country and a new battery (local supplier 4000 mAh Sanyo cells).
I'm an air conditioning technician and ever since I was an apprentice years ago when I went to a training session and the instructor was showing how the bidirectional communication worked on an AC unit with an old Fluke PM95 I've wanted to get something like that myself. Roll on to 25 years later and now I'm in a similar position teaching other technicians how air conditioners work and spending my time dealing with issues that other people can't fix my wish has come true. These days the majority of things that I work on are inverter driven units or I'm troubleshooting noise interference issues on low voltage control circuits so whatever I bought had to be field portable with isolated channels and math functions which tends to narrow your choices.
Apart from the dead battery from it sitting in a cupboard it doesn't look like it has ever seen much action and every time you power it up there is a nag screen about a bonus feature where you can unlock extra recording screens. Does anyone know if Fluke will still give you the code to unlock these extra screen memories?
I've also seen that a firmware upgrade is available from Fluke as it is version 1.07 which can be upgraded to 1.08, the USB interface came in the case and it seems pretty straightforward but are there any things to watch out for?
I've watched the oscilloscope training class video and have a rough idea of what I'm doing but haven't summoned up the courage to connect it to the mains AC part of an air conditioner yet or any of the Inverter power stages. So far I've been playing around with it by looking at the waveforms out of an IR receiver amplifier, but I need to work out on my triggering settings to capture the burst of data.
Anyway thanks for listening to my ramblings
