CALIBRATION PROCEDURES

The calibration data for the required instruments can be stored into the calibrator
calys 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, calys 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.
Manuel d'intructions NTA47248-300A4
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
Auxiliary information = High temp trap
The overall capabilities of the combination between calys + Datacal software are the
following :
•
calys can store up to 100 Tags
•
Each Tag can be tested in different calibration steps (Test Point)
•
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 calys
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
•
Direct test of Pressure Transmitters at actual programmed test points or with
an automatic calculation of actual errors with inlet pressure in an acceptable
deviation band from the Test Point level.
PARAMETERS OF AN OFF-LINE PROCEDURE MUST BE FIRSTLY
•
Press [CAL PROC] and select the proper Tag from Tag item (in this example,
the file is associated to the procedure is "Tag1")
