URV Correct
URV Correct is used to correct the Upper range value. For URV Correct, use
CAL_POINT_HI.
Zero Correct
Zero correct is used to perform zero correction to the value.
CAL_POINT_HI is the upper calibrated value. The value must be at least
CAL_MIN_SPAN away from CAL_POINT_LO, and at or below the high range value of
SENSOR_RANGE.
CAL_POINT_LO is the lower calibrated value. The value must be at least
CAL_MIN_SPAN away from CAL_POINT_HI, and at or above the low range value of
SENSOR_RANGE.
CAL_MIN_SPAN is the absolute minimum span between CAL_POINT_HI and
CAL_POINT_LO. CAL_VALUE shows the PRIMARY_VALUE in the units defined
by CAL_UNIT. CAL_UNIT is the engineering unit to be used when calibrating the
device.
Calibration diagnostics
The block contains the date and time when the:
• LRV calibration method was last run
• LRV calibration method was run prior to last time
• URV calibration method was last run
• URV calibration method was run prior to last time
• Restore calibration method was last run, and
• Calibration Zero method was last run.
Sensors
SENSOR_RANGE is the absolute maximum end of the sensor range, the units of those
limits, and the decimal point position (number of significant digits to the right of the point).
SENSOR_SN shows the sensor serial number. SENSOR_CAL_METHOD is the last
calibration method. SENSOR_CAL_LOC is the last calibration location.
SENSOR_CAL_DATE is the last calibration date. SENSOR_CAL_WHO identifies the
person that last calibrated the sensor.
SENSOR_ISOLATOR_MTL is the material used in the sensor isolation diaphragms.
SENSOR_FILL_FLUID shows the type of fill fluid used in the sensor.
