DC and AC Current
Note
To measure current (up to 200 mA), the NI 4050 requires the CSM-200mA current
shunt module included with your NI 4050.
To measure current up to 10 A, NI provides an external shunt package (CSM-10A)
Tip
for your convenience. Refer to the CSM-10A and CSM-200mA Current Shunt Modules
Installation Guide included with your CSM-10A shunt for information. Refer to
