Open: with a short “beep” sound。No connected
pins LED are off. Example: Test HDMI (A Type) to
HDMI (A Type) cable that pin #2, #5, #8 and #11 are
not connected , or test HDMI (A Type) to Mini-HDMI
(C Type) cable that pin #1、#4、#7、#10 are not
connected. (Fig 4.)
Short: With three short “beep” sound. Shorted pins
LED will light up at same time. Example: Test HDMI
(A Type) to HDMI (A Type) cable that pin #4、#5、#6
are shorted or test HDMI (A Type) to Mini-HDMI
(C Type) cable that pin #4、#5、#6 are shorted. (Fig 5.)
Crossover: With two short “beep” sound. Crossed
pins LED will light on at same time. Example: Test HDMI
