The following selections can be made:

- 'TIME'

The distance between the TIME cursors is expressed in sec
onds,

- T/TIME"

The distance between the TIME cursors is expressed in Herz,

- ’RATIO'

The distance between the TIME cursors is expressed in a
percentage of a previous set distance between the cursors

(100%) and the current distance (xx%) between the cursors.

The ratio is set to 100% at the moment the ’RATIO’ bezel

button is pushed,

- ’PHASE'

The distance between the TIME cursors is expressed in de
grees of a previous set distance between the cursors [360°)
and the current distance (xx°) between the cursors.
