The auto-calibration feature of the DMT152 transmitter is an automatic procedure that greatly reduces the possible drift in the dry end of the dew point measurement.
Auto-calibration is performed:
- at 45-minute intervals
- at shorter intervals if Td is near the dry end of the measurement range
- when the transmitter is powered up
- when the measured environment changes rapidly.
Auto-calibration is carried out only if several criteria for the measurement environment are fulfilled. This ensures the reliability of the adjustments, and maintains the excellent long-term stability.
