Page 13: Calibration
4.3.2 Calibration Calibration Intervals The CDTX-111 Monitor and Sensor combination once calibrated will require calibration checking/recalibration at 3-6 monthly intervals, however this does depend on the application. The calibration of the instrument can be effected by seasonal variations in the measured effluent, however only knowledge of the application can determine the re-calibration interval required. - Page 14 4.3.2.2 C0、C100—temperature calibration CDTX-111 has temperature measurement function, for the automatic temperature compensation, and also can be displayed on the monitor. Temperature calibration requires a high and a low constant temperature environment. Such as ice water mixture (0℃) and boiling distilled water (100℃).
- Page 15 Use boiling water (100°C) to calibrate 4.3.2.3 CC—auto/manual temperature compensation switch CDTX-111 has Auto and manual temperature compensation function. The user can select between two modes of compensation by the CC in the menu. ENTER Press into CC and display CC0 or CC1. CC0 is Auto temperature compensation, CC1 is manual temperature compensation.
