Error -221 when runing Single Measurement Example in Keithley 2700 with 7702 module

Hello All,

I am trying to use the examples provided in the Keithley library in LV 15. I am using ''Keithley 27XX Single Measurement'' for front and rear panel measurements. As far as the front panel is concerned I don't think there is any problem. But while using the rear panel with 7702 module I can only measure DC Voltages and nothing else (ACV, DCi,DCV,Resistance etc). Every time I try to measure some thing other than DC voltage I get an error message, error-221(Settings conflict). I am attaching the file too. Any kind of help is appreciated.
