LOCAL Key
The LOCAL key cancels the remote state and restores 1~
cal operation of the instrument.
LOCAL
El
Since all front panel keys except LOCAL are locked out
when the instrument is in remote, this key provides a
convenient method of restoring front panel operation.

mmand. (See paragraph 42.4).
Note that the LOCAL key is also inoperative if the LLO
(Local Lockout) command is in effect.

BUS DATA TRANSMISSION TIMES
A primary consideration is the length of time it takes to
obtain a reading once the instrument is triggered to make
a conversion. The length of time will vary somewhat de-
pending on the selected function and trigger mode. Table
47 gives typical times.

Times
Tl = One-shot on Talk
G5 = Binary rdgs: IEEE std 754 single-precision,
bytes in normal order for Motorola ClWs.
RI = ZnA range
5’3 = Digital and Analog Filters enabled.
