NOTE
1:
Spaces,
nulls,
or
zeros occurring before byte
1
are ignored
by
the counter.
NOTE
2:
Byte
1
may
be omitted and
a positive mantissa
assumed.
NOTE
3:
Bytes
2 to
11
may
have up
to
9
digits
and a decimal
point.
The decimal
point,
however,
is
not
essential.
After entry
of 9
digits
(without a
decimal
point),
additional
digits
are
ignored
and a
GPIB programming
error
is
generated.
Excess
digits
that are
truncated
will
still
increase the
power-of-ten
stored.
Also,
if
fewer than
9
digits
are
needed,
unused bytes
may
be omitted.
NOTE
4:
Spaces
or
nulls
entered
between
bytes
11
and
12
are ignored
by
the counter.
NOTE
5:
Bytes
12 to 15
(exponent group)
may
be omitted.
Also,
byte 13
may
be omitted
or
transmitted as a space
(a
positive
exponent
should
be assumed
in
either instance).
NOTE
6:
Byte
15
may
be omitted
for
a
single-digit
exponent.
