Go/NoGo LIMIT Testing
The 42L Series load modules have built in Go/NoGo test capability as part of their
measurement systems. This allows abnormal conditions to be detected automatically so an
EUT can be passed or rejected quickly in a production test environment.
6.4.1
Limits
The Go/NoGo is based on comparing measurement data against user provided upper and
lower limit settings for voltage, current and power in the LIMIT system.
This creates a GO band (shown in green in the illustrations below) and a NoGo area. If the
measurements fall inside the green zone, the test continues with the next step in an auto
sequence. If not, a NoGo condition is flagged.
Go/NoGo has different implications depending on the operating mode selected. This is
illustrated in the diagrams below.
6.4.2
Go/NoGo Testing in CC Mode
In constant current mode, the voltage limits are used to determine the pass or fail area for
the input voltage.
