4.2.2 Readout for Cutoff Current and Measured Current
22
CURRENT Readout (Digital Ammeter)
When the Tester is in the TEST-ON status (status that the
TEST
message 29 appears), the
CURRENT readout
22
indicates the measured output current; when the Tester is in other status
than the TEST-ON status, it indicates the preset upper or lower cutoff current. It is a 3-digit 7-
segment readout.
Display change between upper and lower cutoff current settings 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
33
has disappeared. The
UPPER
message
23
means that the
Tester is in the status for setting the upper cutoff current; the
LOWER
message
24
means that
the Tester is in the status for setting the lower cutoff current.
You can increment/decrement the upper or lower cutoff current with the keys
12
when
the Tester is in the READY status (status that the READY message
28
appears) and the
KEYLOCK
message
33
has disappeared. (If you press the
SHIFT
key
16
at the same time,
the increment/decrement rate is multiplied by 10.)
If the lower cutoff current is higher than the upper cutoff current and the lower pass/fail
judgement function is ON, the
mA
display (unit of measure) blink and the
READY
message
28
disappears to alert you to that the setting is illogical and the test cannot be done. When the
lower cutoff current has become lower than the higher cutoff current or when the lower pass/fail
judgement function is turned OFF, the
mA
display automatically stops blinking and the Tester
resumes the READY status.
Of the AC/DC models (TOS5101 and TOS5051), the upper cutoff currents can be preset
mutually independently for AC test mode and DC test mode, and the lower cutoff currents also
can be preset mutually independently for AC test mode and DC test mode.
