key
The key selects the upper or lower cutoff current. If you press the key while keeping the
SHIFT
key
16
pressed, the lower pass/fail judgement function is turned ON or OFF.
The UP/LOW key is enabled when the Tester is in the READY status (status that the
READY
message
28
appears) and the
KEYLOCK
message
33
has disappeared. It is disabled
when in the TEST-ON status (status that the TEST message
29
appears) or when the Tester is
delivering the result of judgement (when the PASS message
30
or the FAIL message
31
appears).
1. When
UP/LOW
key alone is pressed
Each time as you press the
UP/LOW
key, the upper or lower cutoff current is selected and
the
UPPER
message
23
or the
LOWER
message
24
appears.
The UPPER message
23
means that the upper cutoff current has been selected, the value
is displayed on the CURRENT readout
22
, and you can adjust the value with the
keys
12
.
The
LOWER
message
24
means that the lower cutoff current has been selected, the value
is displayed on the CURRENT readout
22
, and you can adjust the value with the
keys 12 .
For the AC/DC models (TOS5101 and TOS5051), the upper and lower cutoff currents for
both AC and DC modes of tests can be selected with this key. The settings of cutoff
currents for the AC mode and DC mode, however, are mutually independent.
2. When
UP/LOW
key is pressed while keeping
SHIFT
key
16
pressed
Each time as you press the
UP/LOW
key, the
LOWER ON
message
25
appears or
disappears indicating that the lower pass/fail judgement function has been brought into or
out of effect.
For the AC/DC models (TOS5101 and TOS5051), the lower pass/fail judgement function
is turned ON of OFF with the
UP/LOW
key. This test condition is applied to both AC and
DC modes of tests — that is, the setting for one mode applies automatically to the other
mode also.
