4. Clear the PROTECTION status (“PROTECTION” is lit)
The tester will clear the PROTECTION status and behave follows:
(a) Turns OFF the “PROTECTION” message.
(b) Turns OFF the PROTECTION signal fed through the SIGNAL I/O connector.
However, the tester will not clear the PROTECTION status if the interlock pins of
the SIGNAL I/O connector are open or if the high voltage supply section is over-
heated during a DC test (TOS5051A only). In this case, clear the interlock signal
(for details refer to section 6.3.3, “Interlock Function” on Page 6-24) or wait until
the tester cools off (for details, see section 6.2.4, “Setting the Test Time” on Page 6-
14) and then reset the PROTECTION status with the STOP switch.
5. Clear the READY status (“READY” is lit)
The tester will clear the READY status and behave as follows:
(a) Turns OFF the “READY” message.
(b) Turns OFF the READY signal fed through the SIGNAL I/O connector.
Normally, when you release the STOP switch, the tester enters the READY status
(“READY” is lit). In the following cases, however, the tester will not enter the
READY status.
1. The cause of PROTECTION status remaining un-eliminated
(a) The interlock pins of the SIGNAL I/O connector on the rear panel are open.
(For details, refer to section 6.3.3, “Interlock Function” on Page 6-24.)
(b) When the high voltage supply section is overheated during a DC test
(TOS5051A only). (For details, refer to section 6.2.4, “Setting the Test Time.”)
2. The test voltage remaining undischarged
This is a state in which the DANGER lamp remains lighted even though the
“TEST” message is OFF.
3. A period of approximately 0.5 seconds elapses after releasing the STOP
switch when the DOUBLE ACTION switch of the TEST MODE switch is
set to ON.
If the DOUBLE ACTION switch of the TEST MODE switch is set to ON, the
tester will enter the READY state when you release the STOP switch. Then,
when a period of approximately 0.5 seconds elapses, the tester will automati-
cally clear the READY status. For details, refer to section 6.5, “Settings for
Special Test Modes” (Page 6-29).
4. The STOP switch is released while the START switch is pressed.
• If the FAIL MODE switch of the TEST MODE switch is set to ON, clearing of
the FAIL status (“FAIL” is lit) or the PROTECTION status (“PROTECTION” is
lit) can be done only with the STOP switch.
• For details, refer to section 6.5, “Settings for Special Test Modes” (Page 6-29).
