As a follow up to Garrison's answer, any readings above zero on digital display alarm MUST be taken seriously. It means 1 of 2 things, your alarms is testing (in teh 200's, and quickly changes to zero - may show "888") or there is CO. at 117, that is a significant number and you need to get out and call the fire department - from outside the house. DO NOT VENT the house, it will delay your leaving but also, if it is a slow leak, by the time the FD arrives, they may not register anything. just get out.
