1 Measured voltage
value
Indicates the voltage in the FAIL state.
2 Upper-limit value
icon and Lower-
limit value icon
The symbol appears when the upper-limit value is set,
and the symbol
appears when the lower-limit value is set.
3 Measured current
value
Indicates the current flowing between the HIGH and LOW
terminals in the FAIL state.
4 Test time elapsed
Indicates the time when the unit switched to the FAIL state.
If the test time has been set, the remaining test time is
displayed. If the test time is set at OFF, the period of time
during which a voltage is output is displayed.
5 Test-voltage type
Indicates the test type (AC 50 Hz, AC 60 Hz or DC.)
6 FAIL
Indicates that the unit is in the FAIL state.
FAIL
lights up
with UPPER to indicate
UPPER FAIL
, and with LOWER to
indicate
LOWER FAIL
. If the output voltage deviates from the
comparative-voltage range and switches the unit to the FAIL
state,
UPPER
,
LOWER
,and
FAIL
light up.
Danger lamp
Indicates that a voltage is being output. The lamp stays on during the test
(including ramp-up time and ramp-down time). In the withstand-voltage
mode, this lamp remains lit even after completion of the test, if a voltage
higher than the safety voltage (approximately AC 0.03 kV or approximately
DC 0.06 kV) has flowed between output terminals.
Analog voltmeter
Indicates the voltage being output in withstand-voltage test. The analog
voltmeter is not held even if the FAIL Hold function is disabled.
Indicates the voltage value being output.
External I/O
The
W-FAIL
――――――――――
signal and either the
U-FAIL
――――――――――
or
L-FAIL
――――――――――
signal come on when
FAIL
lights on the fluorescent indicator. (If the output voltage fails to reach
±
5% of the set test voltage, or if it deviates from the set test voltage,
UPPER
,
LOWER
,and
FAIL
light up, and the
W-FAIL
――――――――――
,
U-FAIL
――――――――――
,and
L-FAIL
――――――――――
signals turn
ON.) Both the
W-FAIL
――――――――――
and
U-FAIL
――――――――――
signals, as well as the
L-FAIL
――――――――――
signal
remain ON as long as the FAIL state is held. The
W-FAIL
――――――――――
,
U-FAIL
――――――――――
and
L-FAIL
――――――――――
signals are turned OFF when the
FAIL
light on the fluorescent indicator
goes out. If voltage remains in the output-voltage terminal following the
termination of a test, the
H.V.ON
――――――――――
signal remains ON. When the
DANGER
lamp
goes out, the
H.V.ON
――――――――――
signal is immediately turned OFF.
