OPERATION PROCEDURE
27
Fig.3-17 DOUBLE ACTION
PASS HOLD
For the PASS HOLD mode, set the switches as shown in Fig.3-18.
When a PASS judgement is made in the standard mode, the Tester generates a PASS signal only for
approximately 50 ms. When in the PASS HOLD mode, the PASS signal is continuously held until
the STOP signal is applied.

■
MOMENTARY
For the MOMENTARY mode, set the switches as shown in Fig.3-19.
When in the standard mode, once the START switch is pressed, the TEST ON state is maintained
until the period set by the timer elapses or the STOP switch is pressed. When in the MOMEN-
TARY mode, the TEST ON state is maintained only for the period the START switch is kept
pressed.
Fig.3-19 MOMENTARY mode
As you release the START switch, the test stops instantaneously. Thus, the MOMENTARY mode is
advantageous from the viewpoint of operation safety.
Still higher operation safety can be attained by operating the Tester in the MOMENTARY mode
and using RC02-TOS Remote Control Box (both-hand type, option) in conjunction.
When test is made with the timer, the Tester generates a PASS signal for approximately 50 ms after
the test for the period preset by the timer has elapsed, and then the test ends.
•
When in this mode, the READY signal is not generated.
■
FAIL ALARM
For the FAIL ALARM mode, set the switches as shown in Fig.3-20.
When the Tester is set in the standard mode, as a remote STOP signal is applied, the test voltage is
cutoff and the FAIL alarm and PROTECTION state and PASS signal are reset as in the case that the
STOP switch on the front panel is pressed. When in the FAIL ALARM mode, as a remote STOP
signal is applied, although the output is cutoff and the PASS signal is reset, the FAIL alarm and the
PROTECTION state are not reset. To reset the FAIL alarm and PROTECTIONS state, press the
STOP switch on the front panel.
This mode provides an effective means for con
fi
rming the FAIL alarm when HP01A-TOS or
HP02A-TOS High Voltage Probe (optional) is used.
