45th Day OF attaChMent

The last two pumps are not done yet as they failed the battery test even though they are charged overnight. The problem was battery faulty and lee chong ordered the batteries for the infusion and syringe pump as there are no spare ones in the inventory store. The syringe pump, which was initially have the occlusion out of range, has the battery failure so lee chong just exchanged the battery with another syringe pump. The reason behind it is he made one of them able to be used instead of two syringe pumps waiting for parts. I just found out that the occlusion adjustment resistor is the variable resistor 6 on the main PCB board. I got to learn something new today.

Remember the otoscope that i am dealing with yesterday? After charging overnight, i just found out the battery is unable to be charger by the adaptor as the unicell rechargable battery is slightly shorter than the original welch allyn 3.5V rechargable battery. not only that, it is also not the compatible one for the red head otoscope as the unicell battery was meant for the yellow head otoscope which were condemned long ago. Initially, i thought it is the adaptor's problem. After asking Mr Toh and checking the adaptor with digital multimeter, it does not seems like it is the main problem.
