Limit Tests
Model 6485 Picoammeter Instruction Manual
Limit testing
As shown in
, there are two limit tests that can be performed on a DUT. Limit 1
is used as the wide pass band and Limit 2 is used as the narrow pass band. It is up to the
user to specify limits that conform to this pass band relationship.
Figure 8-1
Limit tests
shows an example where the HI and LO limits for limit 1 are ±2mA, and the Hi
and LO limits for limit 2 are ±1m
Α
. A 0mA reading passes both limit 1 and limit 2 tests. A
+1.5mA reading passes limit 1 but fails limit 2. A +2.5mA reading fails both limit 1 and
limit 2.
