You have completed adjusting the AC voltage modes of the NI 4070/4072. 
Select one of the following options:

•

If you are performing additional adjustments, refer to the following 
sections, as applicable:

–

–

For the NI 4072, adjusting the capacitance and inductance is required. Skipping 

this step causes an incorrect adjustment of the device.

•

If you are not performing additional adjustments, refer to one of the 
following sections:

–

—to verify your new calibration 

coefficients before saving them to the EEPROM

–

—if you do not want to 

verify the adjustments you have just made

If you do not use the current modes (DC and AC), or the accuracy is 
insignificant for your application, you can skip this section and select one 
of the following options:
