/O_S_REJ
/O_S_OVER
The /O_S_REJ or /O_S_OVER signal
will go low when the secondary
measurement is over D_Max or
under D_Min, whilst in C/D , R/Q,
C/R or L/R mode. The signals will go
high at time T4
/O_EOM The End of Measurement signal
becomes active low when the Bin
comparison/assignment has
completed. The signal goes high
after the next time I_E_TRIG is active
low.

Parameter Input Signals
/I_E_TRIG Measurement start signal. This
signal will trigger the LCR-800 to
start a measurement when the
signal is pulsed for at least 5us. It
is triggered by the falling edge of
the pulse.
/I_K_LOCK The key lock signal disables the
panel keys when the signal is low,
and enables the panel keys when
the signal is high.
