Setting the Horizon Trend Scale
The horizon trend scale is defined with respect to the horizon. If your horizon is set to 100 and you
select 20 as the horizon scale delta, the upper limit of the horizon scale will be 120 and lower limit 80.
To set the horizon trend scale delta,
Select the horizon trend.
Select Set Scale Delta and select a value to define the distance between the horizon and the
upper and lower scale limits.
Be aware that changing the horizon trend scale can change the angle of the trend indicator, without the
patient's condition having changed.
If a measurement exceeds the outer limits of the scale, the wave will be clipped and you must either
reset the horizon or the horizon trend scale to display the values outside the scale limits.
