In this blog, you will see how to get/set the continuous crawl interval using the Powershell in SharePoint 2013.
To get the continuous crawl interval:
- ############# Get the Continuous Crawl Interval in SharePoint 2013 #############
- $ssa = Get-SPEnterpriseSearchServiceApplication
- $ssa.GetProperty("ContinuousCrawlInterval")
To set the continuous crawl interval:
- ############# Set the Continuous Crawl Interval in SharePoint 2013 #############
- $ssa = Get-SPEnterpriseSearchServiceApplication
- $ssa.GetProperty("ContinuousCrawlInterval",20)

You have a typo for setting the continuous crawl (You have Get instead of Set)
