    Press ESC or MENU to exit the SDI-12 Address menu. 2.7 APPLYING A CUSTOM CALIBRATION The PROCHECK can use custom calibration for certain sensor types. Custom calibrations apply directly to the raw analog-to-digital count (ADC) in the form of a fifth-order polynomial.
  • Page 11 OPERATION To enter a custom calibration into the PROCHECK: Navigate to the Configuration tab (Figure 9). Figure 9 Configuration tab Select Calibration Type. Select the sensor type (Figure 10). Figure 10 Selecting the sensor type Highlight Medium (Figure 11). Figure 11 Toggle the medium type for calibration Press ENTER until the medium type is Custom.
