NOTE
Normally the SEC/DIV settings are calibrated when the VAR
control is in the fully clockwise (detent) position. However, if a
front-panel setup had been recalled from the Store/Recali
Setup memory, it is possible for the SEC/DIV settings to be cal­
ibrated or uncalibrated with the SEC/DIV VAR control in any
position. When the controls are rotated, normal variable oper­
ation returns.

long as the reference delay plus the delta delay is less than 10

The cursors cannot be positioned left of the 1st or right of the
11th vertical graticule lines.
