Section 4: Using the Model 9100: Mark/Period Function 4.10-7
Final Width = 215mm
Mark/Period Ratio Limits
The Mark and Period time-intervals can be adjusted over their ranges of values shown in
the tables, provided that the Mark time-interval is shorter than the Period time-interval.
An audible warning will be given if an attempt is made to set a Mark or Period time-
interval which would produce a Mark/Period ratio of 1 or greater (also see the * and **
minimum difference limits shown beneath the table of pulse-widths above). The user
must reset either the mark or the period to give a ratio less than 1. This rule applies whether
OUTPUT is OFF or ON.
Increasing Mark or Period Time-Interval Value
Using the
key in Digit Edit facility; an audible warning will be given if the new value
is too large for the present span of time-intervals, with a reminder on the screen. The user
must change to the next lower resolution, with a larger span of intervals, using the
key. This rule applies whether OUTPUT is OFF or ON.
When using either the X10 screen key or the Direct Edit facility; if the new value is too
large for the present resolution, a lower resolution will be activated with a larger span of
time-intervals. No warning will be given. This rule applies whether OUTPUT is OFF
or ON.
Decreasing Mark or Period Time-Interval Value
Using Digit Edit; time-intervals down to 0.01ms lie within all spans, but to select intervals
shorter than this, one of the three lower spans of intervals must be used.
If the required time-interval lies between steps of the present resolution, then the user
must increase resolution using the
key, also reducing the span of intervals. This
rule applies whether OUTPUT is OFF or ON.
Using either the ÷10 screen key or Direct Editing; if the required time-interval lies
between increments of the present resolution, a greater resolution will be activated with
reduced span. No warning will be given. This rule applies whether OUTPUT is OFF or
ON.
