Auto Align - Defaults to the alert state. When set to Alert, the auto align feature causes a message to appear 24 hours after the last alignment to alert tell you that the instrument needs to be aligned. This message will also appear if there is a change of ambient temperature greater than ± 3° C. Use the Align All Now key.

When set to the On state an alignment (which slows down measurements) automatically occurs every 5 minutes or when a change in ambient temperature of greater than ± 3° C has occurred.

•Align All Now - Immediately activates an alignment on all of the instrument’s standard RF, IF, and ADC alignments. All other operations are stopped and the alignments progress will be visible on the display.
