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:

"*OPC?\n"
"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

Terry
