6.To test the current function, press the "Current" softkey. A sequence of self tests is run. A brief description of each test follows:

a.5725A Current Shunt: Checks the current cabling and the calibration amplifier on the Current Amplifier assembly (A2).

b.5725A Current Zero: Grounds the input and shorts the output of the Current Amplifier, and verifies that the output is close to 0A.

c.5725A Current Gain: Shorts the output of the Current Amplifier, applies a voltage input, and verifies the output current. This confirms integrity of the error amplifier circuit in the Current Amplifier assembly.

d.5725A Current Monitor: Runs the analog monitor circuit on the High Voltage Sense Assembly (A6) in the current function and verifies that it operates correctly.
