Attachment Day 18Wednesdaymorning i report to office.William had to service the CUSA machine.we did not know the fault at first but as soon as we started testing, William discover that the tester meter had the cable short together and burn the ultrasound PC board.William had to change the board and test again.after changing the board, William had to service the test meter and make sure that the wire connecting to CUSA is not short.He took out the cable, follow the line and make a new cable following the same connections.He soldered the wire together and put them back to the machine.Using multimeter to find out that whether the new wires has any accidental link or short to each other.small or minor mistakes can cause the whole machine to be malfunction and it is quite serious especially when the machine is new!when the repairing work is done, we started to test the machine according to the checklist given.everything is within range and the machine work just as fine so we pack up.it was about 1.30pm and we have not eaten our lunch.But we were too tired to move so we rest at the workshop for a while and went NTU to have our lunch after that.after lunch we went to Ang Mo Kio's KK women's clinic for PM services on ultrasound machines.we did 2 ultrasound machines there and was really tired out after finishing the job.pics:
