Caution
• Be sure to read Chapter 3 “WARNINGS AND CAUTIONS FOR
OPERATING THE TESTER” (Page 3-1) of this manual before start
using the Tester.
• Before turning ON the POWER switch, be sure that the
TEST
VOLTAGE
control
6
is in the fully counterclockwise position (“0”
position).
• If you want to enter a setting value you have selected, wait approxi-
mately 0.5 seconds before turning OFF the POWER switch. If you
turn off the switch without waiting for this period, the value may not
be successfully entered.
• Normally, as you turn ON the
POWER
switch, the TESTER will
become the READY state (the READY lamp
28
will light up).
However, the lamp will not light up in the following cases:
(a) The Tester is in the PROTECTION status.
i. The interlock pins of the SIGNAL I/O connector
37
on the rear
panel are open.
(For detail, refer to Section 6.3.3 “Interlock Function”)
If the above is the case, eliminate the interlock signal and reset
from the PROTECTION status with the
STOP
switch 3
and then start operating the Tester.
ii. When in DC test (for TOS5101 and TOS5051 only), the high
voltage supply section is overheated.
If the above is the case, wait until the Tester cools off and then
reset from the PROTECTION status with the
STOP
switch 3
and then start operating the Tester.
(b) The lower cutoff current setting is higher than the upper cutoff
current setting and the lower pass/fail judgement function is ON.
If the above is the case, make the lower cutoff current setting
lower than the upper cutoff current or turn OFF the lower pass/
fail judgement function and then start operating the Tester.
(c) The
POWER
switch is turned ON while the
TEST VOLTAGE
switch 5 is caught on a midway in turning from one range
position to another range position.
When in the above state, the TEST VOLTAGE RANGE message
19
will indicate 0 kV, both
AC
/
DC
test mode message
20
will
appear at the same time (except for TOS5050) and will blink to
show that no range selection has been successfully accomplished.
If the above is the case, turn the TEST VOLTAGE switch
5
accurately to a range position you may require and then start
operating the Tester.
