When i use the example file of Delta mode labview file from the Keihtley, it shows lot of errors. First, when i run the labview program, the delta mode is armed in 6221 and immediately coming back to normal. 2182A  displays like over flow eventually. at the end the result is like 'buffer none'. can anyone help me to figure it out? please.

why does the 6221 isn't supplying any current and no voltage or resistance measurement. The following condition was given for the delta mode

HI and LI is default value of 1 mA current.

20000 msec time out

voltage range 'auto'

compliance current set 10V

RS232 used to connect 6221 and 2182A and GPIB is used for computer connection
