Before connecting a connector, see "Before Connecting EXT I/O" (p. 11). Use of EXT I/O
enables the following control functionality:
• Measurement start (TRIG)  Measurement end (EOM, INDEX)
 Acquisition of judgment results (HI, IN, LO, ERR)
• Measurement start (TRIG)  Measurement end (EOM, INDEX)
 Acquisition of measured values (BCD_LOW, BCDm_n, RNG_OUTn)
• Panel load (LOAD0 to LOAD3, TRIG)
• General-purpose I/O (IN0, IN1, OUT0, OUT1, OUT2)
The functionality described in "Performing an I/O Test (EXT I/O Test Function)" (p. 117)
provides a convenient way to check external I/O operation.
