To enter the capacitor terminals into the Editor C2 test dialogue box, add the
terminals for the first capacitor ‘X’ into the ‘High’ and ‘Low’ areas. For example
if the capacitance is between terminals A and B, add A to the ‘High Terminals
(X) ‘Used’’ area and ‘B’ to the ‘Low Terminals (X) ‘Used’’ area.
Then click on the ‘Terminals (Y)’ button and add the ‘High’ and ‘Low’ terminals
for the second capacitance.
Choosing Test Conditions
For optimum accuracy and performance choose test conditions based on the
nominal value of capacitance as listed in the previous capacitance section.
The test conditions can also be determined automatically by the ATi according
to this table:
Voltage
Specified Auto Auto
Frequency
Specified Specified Auto
Note that a ‘fixed’ voltage signal cannot be used with an ‘Auto’ frequency.
Use the Editor’s ‘Measure’ button (together with a sample part) if you are
unsure of how to choose the test conditions.
See also the notes relating to choosing tests conditions for capacitance in the
previous section.
Choosing Test Limits
The test limits are entered as a + and – percentage around a nominal ratio.
Use the PC Editor’s ‘Measure’ button (together with a sample part) if you are
unsure of the nominal value.
If the "User Offset Enabled" check box is checked, a value can be entered into
the edit box. The value entered is then added to any results returned from the
AT tester.
