Step Action
4
Short the two calibration pads at the upper-left corner of the HLAI FTA as shown in
Figure 215 to start the calibration. For the Galvanically Isolated FTAs, two pins in the
Marshalling Panel connector are shorted together.
5
Ensure that the calibration target on the HLAI Detail Status display has changed back
to
ENABLE CALIBRATION , indicating that the zero and span calibration process has
completed. Check for the Soft failure CALIB ABORT , which indicates bad calibration.
6
Disconnect the calibration voltage source wiring.
7
Inform the operator that the HLAI can be returned to on-line operation.
