Transition for calibration scripting

Virtual variable calibration inheritance accessed by:

• EvCalibration.UseCalibrationInheritance
• EvVariablesCollection.UseCalibrationInheritance

EvCalibration.UseCalibrationInheritance and EvVariablesCollection.UseCalibrationInheritance are not supported.

Virtual variables inherit their Transducer and SourceCal (Calibration Source) from the first operand. The first operand's LocalCal (from the operand's Calibration page of the Variable Properties dialog box) is not inherited.

As a result, COM support for calibration inheritance is not necessary. However the virtual variable's calibration settings can be set/modified using an ECS file. There are core calibration settings that virtual variables use.

Refer to Calibration for virtual variables for more information.

Access or change calibration settings using EvCalibration properties.

EvCalibration methods and properties are simplified.

Access or change calibration setings in an ECS file that is added to a fileset in an EV file using:

• EvFileset allows you to specify the ECS file and variable
• EvCalibration allows you to read values and specify calibration settings and LocalCal

The Echoview 5 calibration setting names have changed (slightly) and many, but not all, of the Echoview 4.90 EvCalibration properties are supported by analogs in Echoview 5.

Calibration setting names (and other defining information) that you can use with COM scripting are found in:

• Common calibration names
• Calibration names used by transducer specific raw variables.

Alternatively, Echoview's current calibration setting name list is available via the Historic calibration dialog box.

Under EvCalibration, calibration settings are referred to by the calibration setting name expressed as a string in a script.

New Echoview 5.0 calibration setting names include:

BeamOffsets
Dt4PowerSetting
Ek60TransducerGain
SamplingFrequency
SimradPulseLength
TvgRangeCoefficient
WedgeVolumeBeamAngle
