External Input and Output Terminals and Signals
Signal functions
Input signal
START Starts a test when it is on.
INTERLOCK Releases the interlock and allows the instrument to be operated when it is
on. The interlock is activated and the instrument enters the protection state
when this signal is turned off. This signal is enabled regardless of the EXT_
EN signal status.
See “Interlock function” (p. 165).
LOAD0 to LOAD7 Allows you to select the test conditions saved using the panel save function.
STOP Ends the test when it is on. This signal is enabled regardless of the EXT_EN
signal status.
EXT_EN Enables the external I/O input signal when it is on. The INTERLOCK and
STOP signals are enabled regardless of the status of this signal.
LD_VALID Executes panel load selected by LOAD0 - LOAD7 when it is on.
Output signal
ERR Outputs on when a measurement system error occurs
U_FAIL Outputs on when the instrument fails with a test upper-limit value error. The
output timing can be selected from two patterns.
L_FAIL Outputs on when the instrument fails with a test lower-limit value error. The
output timing can be selected from two patterns.
H.V.ON Outputs on when a voltage is applied and remains in the voltage output
terminals.
W-FAIL Outputs on when the instrument fails a withstand voltage test.
W-MODE Outputs on while a withstand voltage test is selected in the test mode.
STEP_END Outputs on when one step is completed during a program test.
ARC_DET Outputs on when the arc discharge is detected during a withstand voltage
test. (p. 92)
PASS Outputs on during pass judgment. The output timing can be selected from
two patterns.
OUT0 to OUT1 General purpose output signals. On is output when the instrument enters the
set state.
TEST Outputs on during a test time. A signal can be selected from four types with
varying output timing.
READY Outputs on when the instrument enters the ready state.
PROTECTION Outputs on when the protection function is activated.
CONT_ERR Outputs on when a contact check error occurs.
IR-FAIL Outputs on when the instrument fails an insulation resistance test.
IR-MODE Outputs on while an insulation resistance test is selected in the test mode.
PROG_END Outputs on when one program is completed during a program test.
