Adjustments
This example performs a 4-wire ohms resistance adjustment for a power
line reference frequency of 60 Hz. Change line 80 to OUTPUT
70903;"CAL:LFR 50" for 50 Hz operation. If a calibration error occurs,
the program displays the calibration error and prompts you to repeat the
adjustment (see Table 5-1 for a list of calibration errors).
