 <- Move left   | -> Move right     | Space bar - Stop  | C - Calibrate  
 Up - Faster    | Down - Slower     | L - Lower limit   | M - Goto Maximum
 N - New motor  | P - Goto position | S - New slew rate | U - Upper limit
 <ret> - Signal | ^W - Refresh      | PF2 - Store       | PF4 (x) - Exit


The motor name and the alias is displayed, furthermore the current position, the slew rate and the possible actions.

Pressing one of the left- and right-arrow keys drives the motor in either direction. Movements are stopped by hitting the space bar.

After you started a move, the current signal is displayed and also the position of the maximum. The signal is determined by evaluating the symbol signal. Usually this is defined in exp_ini.exp, e.g.: signal = [vfc( c1, t1, 0.2)]. Counter c1, which is gated by timer t1, is opened for 0.2 seconds. The contents of c1 is the signal.

The C key allows you to re-calibrate a motor.

The L and U keys set the unit limits. These are reset when you leave the menu.

The M key makes ONLINE move to the maximum.

If N is pressed, ONLINE prompts for a new motor name. The limits and the slew rate are reset, as if you left the menu.

When you start the menu, the current slew rate is set to 100%. The up- and down-arrow keys manipulate the motor speed. Each stroke makes a factor of 2. However, you cannot go beyond the initial value this way. The original slew rate is restored when you leave this menu. A new maximum slew rate can be set with the S option. This change remains valid, after you left the /adjust menu.

The PF2 key stores the data into a file. The filename consists of a generic part, default scan_adjust, and a number. The generic part can be specified by the symbol generic_adjust_name.
