8.5.5 Error Signals Output <ERROR Terminal (B9)>
Indicates that the trigger is activated.
The TRIG_OUT terminal (terminal No.: B8) outputs a low-level signal
(active LOW) at trigger activation.
Output Signal
The TRIG_OUT terminal (B8) outputs a low-level signal (active LOW) at
trigger activation. Once the waveform has been loaded, the signal returns
to HIGH level.

<Timing>
1. Trigger Mode: Repeat, Auto Save:
Indicates that an error occurred on the 8730-10, 8731-10.
The ERROR terminal (terminal No.: B9) outputs a low-level signal (active
LOW) at error occurrence, for example, when data cannot be saved
because the PC card is full.
For details of errors, see 13.1.
Output Signal
The ERROR terminal (B9) outputs a low-level signal (active LOW) at
error occurrence.
The ERROR terminal continues low-level signal output until the
STOP
key
is pressed or a STOP signal is input. (The STOP signal can be input to the
STOP terminal (A5) or EXT_IN terminal (A14).
