Rhett working on a new pointer for a broken scale |
Calibrating and balancing infant scales turned out to be a taller task than expected when Rhett discovered that one of the scales was missing the indicator on the large weight. Instead of letting the scale go to waste he decided to make a new one! We bent a few pieces of scrap metal into shape and then epoxied the new pointer onto the weight. After calibration, the scale worked like a charm!

Hunter spent the entire day fighting to revive an electrosurgical unit that was determined to stay dead. The machine is commonly used to perform delicate surgical procedures, and this item in particular was a major priority to the JPII staff, and they were really hoping we could get it up and running for them while we were here! Despite knowing that it wouldn’t turn on, when we first arrived we were very hopeful that we would be able to get it working since we had trained on this exact model of electrosurgical unit. However we quickly realized that it would be trickier than we first expected. The fuses, cable and power switch were all working fine when tested using a multimeter, which indicated that the issue with the unit was somewhere inside the electronic components of the machine. After doing a deep dive into both the service manual and the circuit schematics, he narrowed down the issue to the power supply board at the back of the device, which wasn’t providing the power that the unit needed to operate. Upon this discovery, Hunter along with Rhett removed this board, replaced it with our DC power supply, and SUCCESS! The unit was able to turn on! This victory however was short-lived, as the unit’s interface still wouldn’t respond to inputs, and indicated much more complex problems associated with the logic board. After struggling with the zombie electrosurgical unit for awhile longer, Hunter and Rhett unfortunately had to declare it dead, but not before the device decided to give them some not so kind parting words for disturbing it’s rest.
