# fieldCalibrationMaxDelta

abstract var fieldCalibrationMaxDelta: Double

Maximum Delta E threshold used when performing in-field calibration (if supported), or NaN if the device does not support this operation. It is recommended to leave this set to its default value, which can vary by device type. If a difference from the reference greater than this value is detected during runFieldCalibration, the command will fail with status CommandStatus.ERROR_SCAN_DELTA.
