Chroma 61502 delay measurement problem

Hello everyone,

I have a problem with delay time measurement - I've programed the Chroma 61502 and on changing the AC voltage, the current Iac measurements takes very long time to respond. As you can see in the picture I've attached it takes 9-10 seconds to display the value on the front panel. Sometimes it can pass 10 seconds and will take 15 seconds and sometimes even more. I'm attacing here a print screen of front panel of array of times and the VI I've build. 

I'd be happy for help.

do you, by accident have autoscaling activated or do you use a fixed current range?

Most of the time a fixed range is a lot faster.

No I've just gave the current limit of 2 A in VI at start of the program, without some autoscaling. I even do not see the option that I can do autoscale. 

Maybe you have more ideas to help me please ?
