<h1>Speedometer</h1>
<p>The Speedometer measures the time from one sensor to another, then calculates the speed by
calculating the distance covered by the time taken.</p>
<p>Enter a Sensor Sysname in 'starts timers on' field. Then enter another Sensor Sysname in
the 'stops timer 1 on' field. Measure the distance between the two, convert that into feet
for your scale and enter that into the 'Distance 1' field.</p>
<p>The speed of your train between the two Sensors will be displayed in the 'Timer 1 Speed'
field.</p>
<p>You can add a third Sensor in the 'stops timer 2 on' field and that will give the speed
between the starts sensor and that sensor in the 'Timer 2 Speed' field. You also need to
enter the value in the 'Distance 2' field in scale feet between the start sensor and this
sensor.</p>
<p>You can select to trigger the start/end of the timers with the entry or exit buttons. The
indicators on the right side of the pane is the state sensors you selected.</p>
