Setting gain for measuring fluorescence

Question

I am using a Biotek Synergy H1 microplate reader and the Gen5 software version 3.12.8. 
 I have been trying to measure fluorescence using the machine, but I am having trouble setting the gain. 
 The default shows <extended> gain and does not allow me to set it to a particular value. When I produce reports, it shows that the gain was zero and sometimes 100. How do I set it so that I can manually put the value?

Hi and thank you for the question! 
 To switch from extended dynamic range to standard range which allows a manual setting you need to click on the edit button next to the read speed selection and switch to "standard". 
 Once you are using standard dynamic range you will be able to type in a gain value within the allowable working range. 
 Typical gain settings-
