standard value 60P.
3.
Connect multiple damaged DUTs to record GET data range: STAN >100P to
confirm short value
Parameter setting calculation:
Assume that STAN is set to 60P.
Open value: Lower Limit
＝
20P/60P=33%, OPEN Upper Limit
＝
50P/60P=83%. Recommended to
take 60%
Short value: Lower Limit
＝
70P/60P=117%, Upper Limit
＝
100P/60P=160%. Recommended to
take 140%
4.3.5
S.CK Single-ended contact check parameter setting
It is valid to connect multi-channel scan box.
S.CK Function: to check if two test leads of a scan port are connected reliably. Generally, it is
connected to the same pin of the DUT, if connected to the connected pins, not greater than 100V.
The setting interface is as follows:
Figure 4.3.5 S.CK setting interface
Contact Check (S.CK) The test parameters are as follows:
VOLT
：
0.50
～
0.500kV
High voltage test voltage value
UPPER
：
0.1uA
～
5.00mA
Current upper limit
SCAN
：
Red
This port performs contact check
Gray
This port ignores contact check
UNIT
：
White
This unit participates in the test
Gray
This unit does not participates in the test
Description:
1.
The actual current is related to the internal resistance of the test loop. The default is the preferred
configuration
2.
The test status is DC power open loop mode, setting parameters and test values are for reference
only
3.
All test points are checked in one test process, test time is configured by test points, after the test is
over, the instrument will automatically perform a 0.2 second rapid discharge.
4.
Total test time = 0.5S + 0.3S * N.
