9.1.2 Signal functions
(1) Input signals
INCOM: The common terminal for input signals.
Isolated from the common terminal for output signals.
/TRIGGER:
An external trigger input signal.
Connected to “EXT TRIGGER” input on the rear panel.
/INTERLOCK: An interlock input signal.
Connected to “INTERLOCK” input on the rear panel.
/KEY LOCK:
A key lock input signal.
Setting this signal to the LOW level disables all the panel keys
except the [STOP] and [LCDOF] keys.
/START:
Start input and has the same function as that of the [START] key
on the panel.
In regular measurement, this signal is for output of measuring
voltage and readies acceptance of trigger input. Starts
measurement when in the Internal Trigger mode (INT).
Starts the measuring sequence when sequential measurement is
ON.
/STOP: Stop input and has the same function as that of the [STOP] key on
the panel.
Turns off voltage output and stops measurement.
Stop input can always be input.
(Not disabled even by /KEYLOCK input, remote state or other
events.)
/OPEN:
Open correction input.
Performs open correction once.
Functions only in a stop state.
/V.CHECK: Voltage check input and has the same function as that of the [V.
CHK] key on the panel.
Executes voltage check once.
Functions only in a start state and when sequential measurement
is turned OFF.
/C.CHECK: Contact check input and has the same function as that of the [C.
CHK] key on the panel.
Functions only in a start state and when sequential measurement
is turned OFF.
[Notice]
Setting of the interlock function CONECT/CUTOFF on the Setup screen is invalid
to the /OPEN and /START input signals of the handler interface.
Note that control of /INTERLOCK input is always necessary.
