Delta Mode - Unable to run NPLC 1 or 5

Hello,

I am running 2400 sourcemeter and 2182a nanovoltmeter into LabVIEW via Delta Mode..

I am using the Kiethley given example 2182Delta_LV6.vi and added custom varialbes for the user as well as a digital filter.

For some reason I am unable to run :SENS:VOLT:NPLC 1 or :SENS:VOLT:NPLC 5... In the user manual it recommends this setting, but when I set it to those values my RQS stage gets fully timed out (50 seconds) and my 2400 stops listening, resulting in 0s. To work I the only setting that works is 0.1.

BUT!

When I "Highlight Execution" it works just fine, with either setting (1 or 5).

Why? and how can I fix this?

Thanks,
Danny

I figured out the difference,

Adding the command

:SYST:FAZ 0

for some reason screws it up, if someone cares to explain it would be helpful.
I added it because it says it allows double Delta speed measurements in the manual.
