UPPER Message
This message means that the value shown on the CURRENT readout
22
is of the upper cutoff
current. Switchover between the upper and lower cutoff currents can be done with the
UP/LOW
key

when the Tester is in the READY status (status that the
READY
message
28
appears)
and the
KEYLOCK
message
33
has disappeared.
When in the TEST-ON status (status that the
TEST

24
disappear and the CURRENT readout
22
indicates the
measured output current.

LOWER
Message
This message means that the value shown on the CURRENT readout
22
is of the lower cutoff
current. Switchover between the upper and lower cutoff currents can be done with the UP/LOW
key
13
when the Tester is in the READY status (status that the
READY
message
28
appears)
and the KEYLOCK message

preset cutoff current can be done.
For the AC/DC models (TOS5101 and TOS5051), this test condition setting is applied in
common to both AC and DC modes of tests.
