Emissions Task Continued - Tuesday 6th January 2015

Throttle Switch
Pin-out Connection

Expected Pattern
(Blue Trace)

Today we resumed the Emissions Practice Task from yesterday and were ultimately assigned to a live rig with a readily available pin-out for ease of completion.  Due to the rig having a cable operated throttle we were unable to gather a Throttle Potentiometer pattern, however the process for doing so was explained and understood.  After an initial 3 minute "Mr Clumsy" impression in trying to simply gather the associated testing equipment and collect keys etc (dropped keys, bent down to pick up keys, phone fell out of pocket - bent down to pick up phone, specs fell out of pocket - bent down to pick up specs, stood up and knocked information folder off of rig breaking folder tie, got as far as the Fiesta and then dropped keys again - at which point I politely requested Isaac if he would mind picking up the keys before I demolished the Workshop)!  "Davey Moment" passed, we were then guided back to the rig where it all started!  Anyway, we eventually set up the Picoscope according to the particular test and set about obtaining a good pattern accordingly.

Good Pattern Returned

Team work and coordination was required between us and we worked well together again. I maintained the pin-out connection with my right hand and operated the throttle pedal with my left, whilst Isaac operated the Picoscope to capture an image portraying a variety of throttle operating conditions.  It was a good result indeed.  We then both sat down together and reproduced the image as a drawing for evidence within our portfolios', and then completed our job cards ready for presenting our findings accordingly.  We were signed off as complete and then set about clearing away our tools and equipment without any further re-appearance of "Tea Bag Hands" for the remainder of the session.

We were then assigned to the practice Wheel Bearing Task, but due to the limited time available of the session, we were only able to complete the planning part of the Job Cards, which were signed off as satisfactory so far.  With the remaining time we utilised some Chrome Books from the classroom upstairs and did a little blogging and research before finally clearing up the Workshop ready to depart for our respective evening destinations.

Thanks also go out to Steve Leonard, Carl Black and the Level 2 Group upstairs, who re-united me with my TNT Woolly Hat, which has been AWOL since before Winter Stand Down (wondered where that went)? Great day and very enjoyable - Thank you all and looking forward to resuming the task next Monday!
