Looking for Criticare 503 (NOT DX) service manual,
« on: March 29, 2022, 01:44:08 pm »
I am in search of the manual for a Criticare Pulse Oximeter to find the calibration/adjustment for the SPo2 function. Mine shows 96% on a known 98% patient. I have two sensors that are known to be good/functional and both read the same 96%. All I can find on the web is the newer 503DX information. My unit is the older model with the LCD display. Thanks!!
