conpin(SMU1, 1, 0);
conpin(GND, 2, 0);
forcev(SMU1, 60.0); /* Generate 60 V from SMU1. */
delay(20); /* Pause for 20 ms. */
measi(SMU1, &ir4); /* Measure current; return */
/* result to ir4. */
This example measures the leakage current of a variable-capacitance diode. SMU1 applies 60 V across
the diode. This device is always configured in the reverse bias mode, so the high side of SMU1 is
connected to the cathode. Because this type of diode has very high capacitance and low leakage current,
a 20 ms delay is added. After the delay, current through SMU1 is measured and stored in the variable IR4.

devint

This command resets all active instruments in the system to their default states.
Usage
int devint(void);
Details
Resets all active instruments in the system to their default states. It clears the system by opening all
relays and disconnecting the pathways. Meters and sources are reset to their default states. Refer to
the hardware manuals for the instruments in your system for listings of available ranges and the
default conditions and ranges.
The devint command is implicitly called by the execut command.
