Hello
I'm using a usb-gpib-hs to communicate with a Fluke 5720A through a self written code with pyVisa. I'm having trouble when i try to apply voltages above 22V, i'm able to put the voltage value in the calibrator, but i can't apply the operate command, the operate command takes the equipament off the standby mode.
Does anybody has the Ni-max comand to test?

You can check the programmer's manual of 5720A for the supported commands. Using NI MAX's VISA Interactive panel is a utility to send commands and receive response.

The 5700/20 have a limiting parameter for a max output voltage (RTFM) to avoid DUT damage due to operating/operator errors . Maybe it's set to 22V?

The problem has been solved. It is important to use the *cls command at the right time. Below is the sequence and it worked. Now it is time to correct the script.
* RST
OUT 23 V, O Hz
*CLS
OPER
Thanks you.
