For special camera uses, however, it may be helpful to set parameter values outside of thefactory limits.The remove parameter limits feature lets you remove the factory limits for parameters associatedwith certain camera features. When the factory limits are removed, the parameter values can be setwithin extended limits. Typically, the range of the extended limits is dictated by the physicalrestrictions of the camera’s electronic devices, such as the absolute limits of the camera’s variablegain control.The values for any extended limits can be determined by using the Basler pylon Viewer or fromwithin your application via the pylon API.Parameter limits can be removed for the following parameters: Gain parameter for setting gain (remove parameter limits generally available) ExposureTime (remove parameter limits available for some camera models)When the regular parameter limits on the Gain parameter are removed the new limits are setbeyond the regular ones, where the new lower limits can be set to negative values.For more information about the gain feature, see Section 7.2 on page 193.Removing Parameter Limits1. Use the Parameter Limits Selector to select the parameter whose limits you want to remove.2. Set the value of the Remove Parameter Limits parameter.You can set the Parameter Limits Selector and the value of the Remove Parameter Limitsparameter from within your application software by using the Basler pylon API. The following codesnippet illustrates using the API to set the selector and the parameter value:// Select the feature whose factory limits will be removed.camera.RemoveParameterLimitSelector.SetValue(RemoveParameterLimitSelector_Gain);// Remove the limits for the selected feature.camera.RemoveParameterLimit.SetValue(true);You can also use the Basler pylon Viewer application to easily set the parameters. Note that theremove parameter limits feature will only be available at the "guru" viewing level.For more information about the pylon API and the pylon Viewer, see Section 3.1 on page 61.To remove the limits for a parameter value:
