magnification must be reduced or you must make further attempts to improve

TIP: You can use the mouse both for controlling electronic centring and for changing
magnification. However, it is usually more convenient to use the left and right cursor
keys to control centring and the up and down cursor keys to change magnification.
When you are satisfied that the component is reasonably centred at the degree of
magnification that you wish to use then press the button labelled Trace (or press T).
Note: You can start a trace without using the setup dialog; if, for instance, you are
repeating the trace and are sure that the component is centred correctly. Simply select
the Trace menu option or click on the Trace icon (fifth from the left).

electronic signal that is generated by the mechanics at the 0 degree
point of the trace (this is usually when the mechanics is at the "three
o'clock position"). The trigger signal is used for timing and must be
seen twice after the Trace command is given before the trace will
start to appear. This can take over one minute on slowly moving
mechanics.
As soon as the second trigger is seen, the Waiting for Trigger
message will change to Reading Data and the trace will start to
appear on the screen. Immediately after the trace is completed, the
whole screen will be redrawn with the trace shown centrally on the
chart according to the reference standard that has been selected –
unless the View option Raw Data has been selected (see next
section).
