Trigger Function LEDs
:
These LEDs indicate the current status of trigger function
on
display and the current operation functions.
The MULT LED lights on to indicate the
trigger setting status
of multi-trigger type.
The SINGL LED lights on to indicate the
trigger setting status
of Single-trigger type.
The EXT LED lights on to indicate the
external trigger signal
source.
The ON/OFF LED lights on to indicate that the
trigger function
is enabled.
16
Shift mode LED
:
The SHIFT LED light on indicated that the
enter mode is
Secondary Functions right now.
17
Hold mode LED
:
The HOLD LED lights on to indicate that
all modify keys is
disabled.
18
RS-232 Interface LED
:
The RS232 LED indicates the current operation
status with
the RS-232 interface bus.
19
