Patent ID: 7209847

Claim:
A measuring apparatus comprising: a detecting section having a pair of electrode portions and operative to output a potential difference which occurs when the pair of electrode portions are brought into contact with a test subject for measurement; a main body removably attachable to the detecting section and displaying a characteristic value of the test subject determined from the potential difference on a measurement screen on the main body as a measurement outcome; a calibration-related data storage section in the main body for storing calibration-related data including, at least, user identifiers for identifying users who have previously calibrated the apparatus, and a calibration date and time data indicative of the date and time of the previous calibration; and a display output section in the main body operative to fetch data related to a latest calibration from the calibration-related data storage section by reference to the calibration date and time data and then display an indication of a user identified by a user identifier included in the data related to the latest calibration as a calibrator identifiably together with the measurement outcome simultaneously on a same screen as the measurement screen.
