4.13-6 Section 4: Using the Model 9100: Capacitance Function
Final Width = 215mm
4.13.5.1 Capacitance Resolution Thresholds
The different resolutions are distinguished by two characteristics:
• Maximum and minimum values available.
• Absolute resolution of the least-significant digit.
The following table shows the spans of output values for the Capacitance function,
against their associated resolutions.
4.13.5 Crossing Thresholds
Absolute Span of Values
Resolution
0.01pF 0.50000 nF to 4.00000 nF
0.1pF 00.5000 nF to 40.0000 nF
1pF 000.500 nF to 400.000 nF
10pF 0.00050 µF to 4.00000 µF
100pF 00.0005 µF to 40.0000 µF
1nF 000.001 µF to 400.000 µF
10nF 0.00001 mF to 4.00000 mF
100nF 00.0001 mF to 40.0000 mF
Rules, built into firmware, govern passage across thresholds between resolutions:
Increasing Output or Offset Capacitance
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 values, with a reminder on the screen. The user must
change to the next lower resolution, with a larger span of values, 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
values. No warning will be given. This rule applies whether OUTPUT is OFF or ON.
Decreasing Output or Offset Capacitance
Using Digit Edit; values down to minimum lie within the spans shown in the resolution
table. If the required value lies between steps of the present resolution, the user must
increase resolution using the
key, also reducing the span of values. This rule
applies whether OUTPUT is OFF or ON.
Using either the ÷10 screen key or Direct Editing; if the required value 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.
