9 CALIBRATION
PROCEDURES
Eurotron with
CalpMan 2007
, coupled with the powerful
MicroCal 20
calibrator, grants the possibility to keep these instruments under control.
The calibration data for the required instruments can be stored into the
MicroCal 20
memory following the instructions detailed in this manual.
The data of each calibration procedure can be stored together with the name of the TAG, with engineering units, process info, calibration points and a two allowed levels of error.
The calibrator can be used as a generator or as a recorder or both; its input and output terminals can be used to generate, receive and compare info.
After the calibration check,
MicroCal 20
will indicate if the checked instrument is within its specifications or if it has to be verified; and a decision can be made by the plant technicians.
The status of every instrument before and after its calibration can be recorded and recalled later.
Benefits to be gained from this system are:
•
Optimization of the Maintenance period. By keeping a record of the time required between necessary adjustments, the optimum maintenance period can be determined.
•
Print of the Report of Calibration. A calibration report can be printed for each TAG.
•
Aid in maintenance planning. Data can be used to analyze the time and cost required for instrument calibrations and can aid in planning manpower, specifying supplier, etc.
Test and calibration data can be memory stored and downloaded to a PC to document the calibration activity that allows building a quality control chart/data bank from a single
calibration sheet to a detailed historical report.
Each instrument, called “Tag”, to be calibrated/inspected is identified by 16 alphanumeric characters.
Three additional lines of 16 characters are available for a more detailed description of the instrument to be calibrated. A typical example is shown below:
Tag
= Pressure Trx 128
Auxiliary information
= High temp trap
Area n.21T68
Stafford Station
The overall capabilities of the combination between
MicroCal 20
+
CalpMan 2007
software are the following :
MicroCal 20
can store up to 100 Tags
Each Tag can be tested in different calibration steps (
T
est
P
oint)
Each Tag can be identified with an alphanumeric code of 16 characters
Plant location/Plant section can be identified with three additional lines, everyone of 16 alphanumeric characters
The Operator/Inspector’s name can be written with up to 16 alphanumeric characters
The Test procedure can be prepared in a PC and downloaded into a
MicroCal 20
when required
The Test procedure can be eventually directly loaded on the field and downloaded into the PC
Direct test of analog / digital signal and pressure indicators
Direct test of Signal and Pressure Transmitters with comparison between input and electrical signal output
