will

1.
Ohms
fast

(Z1)
and

®
The "!"
character
can be used
with the Parallel
Interface (Option
-07)
(and with the IEEE-488
Interface
Option
-05
in
the
8502A
only).
The
High
Speed
Reading
mode
provides
a
shortened 3~byte binary two's
complement
format response representing
the input
to
the
DmM's A/D
Converter.
Speeds up
to
500 readings
per
second
are possible
in this
mode
of operation.
True
readings
can be computed
from
this
response
using range and
function
dependent
factors
(refer to
Fluke Application
Bulletin
25).
The
High
Speed
Reading
mode
is
suited to
systems
with very
fast processors, to use with stored readings,
or
to
appiications not requiring
direct
numeric
conversions
(e.g.,
zero crossings or
large deviations
from
a
nominai
value).
#
Use
of
the
"V
character
will
place the
DMM
in
the High
Speed Reading
mode
and
trigger the
first
reading.
Subsequent
readings can be
triggered
by sending
the
"?" character.
In
addition, for
the
8502A
equipped
with
the -08A Option, subsequent
readings
can be
triggered
by sending
the
TTL
pulse with the Externa! Triggering
Mode
("G"
or
"Q1"). The
High
Speed
Reading
mode
can be aborted
at
any time by
transmitting a character
other than "?"
when
a
reading
is
to
be
triggered.
The
character sent
in
this
case
will
do
nothing
more
than
cause
the
DMM
to
exit
the
High
Speed
Reading mode,
