12.4 Measurement Calibration data files (.mcd)
Measurement calibration data files always have a default "mcd" extension
unless the user specifies a different extension on purpose. These files can be
used to track changes in measurement calibration data over time. Each time
a measurement calibration is performed, the user will be given the option to
save the present measurement calibration constants in a new mcd file.
Measurement calibration ‘mcd’ files consist of one to four records in a
comma separated value format using the following format :
Position Type
Description
record 1, field 1 string
Source program name. Name of program that created this file
record 1, field 2 string
Program version and date.
record 1, field 3 decimal
Model identification. (see model table)
record 1, field 4 string
file creation date
record 1, field 5 string
file creation time
record 2, field 1 decimal
Voltage measurement calibration coefficient phase A
record 2, field2 decimal
Current measurement calibration coefficient phase A
record 2, field3 decimal
Power measurement calibration coefficient phase A
:Following records are only present if L-series model is two or three phase system:
record 3, field 1 decimal
Voltage measurement calibration coefficient phase B
record 3, field2 decimal
Current measurement calibration coefficient phase B
record 3, field3 decimal
Power measurement calibration coefficient phase B
record 4, field 1 decimal
Voltage measurement calibration coefficient phase C
record 4, field2 decimal
Current measurement calibration coefficient phase C
record 4, field3 decimal
Power measurement calibration coefficient phase C
Notes
: All calibration coefficient values range from 0 to 255. Calibration
coefficients with a value of 256 indicate a failure to bring the measurement
within calibration. If one or more calibration coefficients with a value of 256
occur, check your calibration procedure. Make sure the external
measurement equipment is connected properly and set to the correct range.
It is also possible that one or more measurement values have been entered
wrong.
