Details regarding the Touch Current Display with LLT Offset specifications are shown
below. Note that these accuracies will be the same as the accuracies stated in section
3.1. 620L Functional Specifications
for Touch Current Display (RMS) and Touch
Current Display (Peak). These accuracies apply for the specific current range (Ranges
1-6 in Section 3.1):
Leakage Current Offset Circuit
Leakage Current Offset
Range
0.0-999.9uA
Resolution
0.1uA
Accuracy
Same as the Touch
Current Specifications
Please consider the following:
1. The LLT Leakage meter indicates a value
that is calculated using the formula for
displayed current shown above.
2. The Total Leakage can be calculated as:
Total Leakage = √((Displayed Current)^2 +
(Offset Current)^2)
3. Then the Displayed Current accuracy will
include the Total Leakage Current accuracy
that is the same as the range of the Touch
Current Display (RMS and Peak) accuracy and
Offset Accuracy. When the offset value is
taken by an automatic offset, the automatic
offset accuracy is the same as the relative
range of Touch Current Display accuracy.
Operation of the Offset
This option adds the offset capability to the line leakage test of the 620L. For detailed
information about general test set up procedures, refer to section
4.5. Setting up a
Test
. When the LLT Offset Option is installed, the offset parameter will appear along
with the other parameters associated with a line leakage test. Utilizing this feature
must be done through the Setup Test Parameters window.
