41 DaY oF ATtaChMent
How's today in Alexandra Hospital?? All i can said that it is quite busy but i pretty enjoy working with such wonderful family. Sometimes, the workload for the day may seems hectic but the enjoyment of the learning and the chances of maximising my knowledge gained from Alexandra Hospital are always given by Mr Sin. I am pretty much grateful because of him.
Once again, i did repairing for today. Before starting on my repair on infusion pump and otoscope, i transferred all the signatures to the system and updated some work files on what i had done yesterday like replacing of the oxygen flowmeter. Called up some vendors for quotation to replenish some spare parts in the storeroom. I got a repair assigned by Mr Sin which is the "Battery" LED did not light up when battery is in use. The first thing that came to my mind was to search for the service manual to find the cause. There were 3 causes which are LED defective, connector 9 to connector 19 need to be checked and HIC circuit faulty. I was quite lost while i found out the causes so i asked Mr Sin for some guidance. He taught me how to test the connection of the diode to the IC. i kind of spent half a day to figure out the connection and components as there are at least 30-40 components on the circuit. I got to know a new symbol for relay. Relay is being used for the device to swtich to ac supply when the plug is connected to electrical supply automatically. When the plug is connected, the relay will toggle to the connection that initiate the LED for ac supply to light up. After checking, the diode seems to be working fine. However, the connection from the IC to the jumper which also connected with "battery" LED don't seems to be connected so Mr Sin decided that just change the whole PCB board that has the LEDs. I just hope that the infusion pump will operate fine tomorrow.
Lastly, i just changed the lamp bulb for otoscope as the complaint is the bulb blown.
