Hello There

im using SICL library to send command to the unit continuously, 
somehow, i am able to repeat a list of command about 240-245 times, 
after that, the tester will not responding anymore, 
i need to switch off the tester and re-start again.

Is the tester buffer full ? or something i've missed? 
Commands as below:

"SYST:LFR F50Hz\n"
"VOLT:RANG R20V, (@1)\n"
"CURR:RANG R100uA, (@1)\n"
"SENS:VOLT:NPLC 0, (@1)\n"
"SENS:CURR:NPLC 0, (@1)\n"
"VOLT:LIM 20V, (@1)\n"
"CURR -10uA, (@1)\n"
"OUTP ON, (@1)\n"
"MEAS:VOLT? (@1)\n"
"OUTP OFF, (@1)\n"

I've tried iflush after every iwrite() and ipromptf(), no effect took. 
I've also tried *CLS command every finishing cycle, no effect took. 

Please enlighten me. 
Million Thanks
