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.
