COMMENT ON 2020 SAD Picoammeters (connected to ItoV system in Injector) require yearly Certified Calibration

Log Number: 3876865Logbook(s): Body: 

Polarize Source Cup, FC1 and FC2 Picoameter and ItoV readbacks tested
this morning by inserting each device individually while signal injecting
downstairs in the tunnel. Cycled thru different current values while monitoring
Picoameter and ItoV for each device and readbacks look good. I can now
check them off in HCO. All that is left to test is the 500Kev dump which
requires MBO0I06 magnet power supply on with current setpoint greater than
100 milliamps.
