+5V
Internal +5V: It is not recommended to use the
internal +5 V. If this voltage output is used, the
current should be lower than 0.3 A, and that the
signal line is far from a disturbance source.
19
/PHI
Indicates that the test result is greater than the high
limit set on BIN1 to BIN9.
20
/PLO
The main parameter is lower than the lower limit in
BIN1 to BIN9.
21
/SREJ
The test result is outside the valid range.
22-24
NC
Not connection.
25
/KEY LOCK
When this line is asserted, the keys in the front panel
are locked.
27
28
/EXT.DCV1
The external DC voltage 1: this is a pull-up DC Voltage
pin for optoelectronic coupling signal
(/BIN-/BIN9, /AUX, /OUT, /PHI, /PLO,/SREJ).
29
/ALARM
When circuit is interrupted, this signal is asserted.
30
/INDEX
When the analog test is finished and the UNKNOWN
terminal can be connected to another DUT, /INDEX is
asserted. However, the comparison signal is asserted
until /EOM is asserted.
31
/EOM
End Of Measurement: when the test data and the
compared results are asserted, this signal is also
asserted.
32
33
COM2
The reference ground for external power EXTV2.
34-36
COM1
The reference ground for external power EXTV1.
