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.
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.
Disconnect the calibration voltage source wiring.
Inform the operator that the HLAI can be returned to on-line operation.
