The pronoun "their" is the best choice because it is a plural possessive pronoun that refers to both Cathy and Chris. "His" would indicate that only one person is doing the calibration, and "they're" is a contraction for "they are" which does not make sense in this context. "There" is a location adverb and does not indicate possession.
