Final answer:
To determine the OT factor when the OT range is less than 1000 meters, you can use a method called pacing. Pacing involves counting the number of steps it takes to cover a known distance and then using that ratio to estimate the distance you want to measure.
Step-by-step explanation:
To determine the OT factor when the OT range is less than 1000 meters, you can use a method called pacing. Pacing involves counting the number of steps it takes to cover a known distance and then using that ratio to estimate the distance you want to measure. Here's how you can do it:
- Select a known distance, such as 100 meters, and walk that distance, counting your steps as you go.
- Divide the known distance by the number of steps you counted to get your stepping factor. For example, if it took you 75 steps to cover 100 meters, your stepping factor would be 100/75 = 1.33 meters per step.
- Now, walk the distance you want to measure, counting your steps again.
- Multiply the number of steps you counted by the stepping factor to get the estimated distance. For example, if you counted 60 steps, your estimated distance would be 60 * 1.33 = 79.8 meters.
