202 BSL PRO ManualLengthThicknessColorWhen recording is stoppedMappingSpecifies indicator span in pixels starting from the “Origin”. Default is the smallest of theLength or Width dimensions divided by 2.Specifies the indicator width in pixels, with a selectable range between 1 and 10. The defaultis 1 pixel.Specifies color of the indicator “needle” as Black (default) or White.If the source channel is a Calculation channel, no gauge updating will occur when therecording is stopped. Under this circumstance, the “When recording is stopped” optionsbecome available. This allows the user to specify whether the indicator should not bedisplayed, should be reset to zero, or should retain the last value.For setting up two point mapping: Input to AngleInputAngleDefines the input values in the scaled units. The units shown in the example are volts, butwould reflect the units of the source channel (mmHg, psi, etc.). The Input mapping of theupper scale value is set to a default of 50 of the source channel unit type.Any angle can be entered, but 0, 360, 720, etc degrees means that the indicator will always bepointing straight down.When assigning mapping angles: Because the indicator “needle” must rotate clockwise, thefirst value should be the lower angle. The first value also defines the indicator’s starting anglebut does not to need to be 0 degrees. For example, the Stopwatch Gauge’s starting angleshould be 180 degrees (pointing straight up). If half-circle gauges are used, the starting anglemay be 90 degrees.Indicator is limited to specific mappingIf this option is enabled, and the indicator needle reaches its mapped upper limit, it will stoprotating and turn red. If this preference is not selected, the needle will not change color if thedefined mapping limits are exceeded and the needle will just continue in a clockwiserotation.Visit the online support center at www.biopac.com
