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.
