How to insert delay between each requests in Jmeter

1. Create a transaction controller in Thread group
2. put all your http requests under this transaction controller
3. add constant timer (with value as 2 min) to transaction controller
   (this way it will be applicable to all request within that transaction controller)
4. run your jmeter script

or if only 2 request are there then add only 1 constant timer in between both the requests.
