Continuity test
Continuity test shares the same configuration with 600.0Ω manual resistance measurement mode and
has buzzer output to indicate continuity. The buzzer generates 2KHz beep whenever the reading is less
than 30Ω or 50Ω. The boundary can be selected by S600VEFSEL pin. See Table 12 for details.
In scan mode, it automatically switches to continuity test as resistance value is lower than 600.0
Ω
.
In EF unit, OPO_R, OPO_G, and OPO_Y are LED outputs. OPO_G is high if a complete path resistor
is less than 50Ω/30Ω. Otherwise OPO_R is high.
Diode Measurement
Diode measurement mode shares the same configuration with 6.000V manual voltage measurement
mode and has buzzer output to indicate continuity. The buzzer generates a 2KHz sound whenever the
reading is less than 30mV. If the test circuit is open or the voltage drop between the two ports of the
DUT is larger than 2V, the LCD panel will show “OL”.
