(3) TEST signal OFF timing setting
After a test, timing for the TEST signal output transistor to turn OFF from ON can be set.
FAST The TEST signal turns OFF immediately after a test is completed
without waiting for the voltage between the measurement terminals to
drop.
SLOW The TEST signal turns OFF after the voltage between the
measurement terminals drops below 10 V ± 3 V.
Refer to “Test duration accuracy” (p. 155).
EXT.SW (not isolated against the power supply protective ground terminal and
isolated against the measurement terminals)
The switch signal line plug of the 9299 Switched Probe is connected.
The operation mode can be switched between two modes, CONT and TRIG (the instrument
settings have priority).
Continuous (CONT)
mode
Measurement is performed only while the 9299 switch is being
pressed.
Trigger (TRIG) mode A test starts and stops every time the 9299 switch is pressed.
RS-232C (not isolated against the power supply protective ground terminal and
isolated against the measurement terminals)
RMT is displayed at the top of the screen during communications and any keys other than the
LOCAL key and STOP key are disabled.
Remote control and measured value output can be performed.
Output data setting: OFF/TYPE 1/TYPE 2
• TYPE1
Output: Measured value + judgment
• TYPE2
Output: Measured value (index display 000.0E+06)
