4.11-6 Section 4: Using the Model 9100: % Duty Function
Final Width = 215mm
4.11.5 Crossing Thresholds
4.11.5.1 No '% Duty' Resolution Thresholds
As the '%' resolution is fixed at 4 significant digits, with absolute resolution of 00.01%
between 00.05% and 99.95%, there are no resolution thresholds to cross.
4.11.5.2 Period Time-Interval Resolution Thresholds
The different time-interval resolutions are distinguished by two characteristics:
• Shortest and longest time-intervals available.
• Absolute resolution of the least-significant digit.
The following table shows the spans of output
Period time intervals for the % Duty Cycle
function, against their associated resolutions:
Absolute Span of Time-Intervals Span of Time-Intervals
Resolution for -6.0V — +6.0V Output for -30V — +30V Output
100ns 100.0 µs to 999.9 µs -----
100ns 00.1000 ms to 99.9999 ms 01.0000 ms to 99.9999 ms
1µs 000.100 ms to 999.999 ms 001.000 ms to 999.999 ms
10µs 0000.10 ms to 2000.00 ms 0001.00 ms to 2000.00 ms
Increasing 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 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 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 four 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 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.
