10.3 HANDLER description of transformer single group test
For the sorting of transformer single test, the interface model provided by the instrument is
57BR-4036L, which provides separate sorting of 12 parameters such as /FAIL1-/FAIL12 and the
total /PASS and /FAIL signals.
10.3.1 Sorting logic
The sorting signal of the first parameter in the single group setting page corresponds to /FAIL1, the
second parameter corresponds to /FAIL2, and so on, the last parameter corresponds to /FAIL12.
During the test, which parameter fails the corresponding sorting signal will change. All parameters
are qualified, the PASS signal is valid, as long as one parameter is not qualified, the /FAIL signal is
valid.
10.3.2 Technical description
10.3.2.1 Output signal
Active low, open collector, optoelectronic isolation
Table 10-7 Output signal
/FAIL1-/FAIL12, /PASS, /FAIL
"Analog measurement end" signal
"End of all measurements" signal
Provides an alert when a momentary power failure
or processor interface board reset is detected.
10.3.2.2 Input signal
Optoelectronic isolation
Table 10-8 Input signal
Key lock (locks the front panel keyboard, including
the touch screen)
External Trigger: pulsewidth≥1μS
10.3.2.3 Signal line definition
The HANDLER interface of transformer single test uses three kinds of signals: comparison output,
control input and control output. The following is the signal definition of the HANDLER interface
when using the transformer single measurement function.
