APPENDIX A: MNEMONIC COMMANDS
AFL ANALOG FILTER
AFL= f Sets both analog output filters of the
installed 5D64 module to f (1 through
5). Actual cutoff frequencies corre-
sponding to filter constants are mod-
ule-specific; for the Model 5D64, they
are as follows:
f = 1 : 0.2 Hz
f = 2 : 2 Hz
f = 3 : 20 Hz
f = 4 : 200 Hz
f = 5 : 2000 Hz
AFL Reads current filter-constant values—
which, for a 5D module installed in a
3000PLUS, are always the same;
returns f,f.
LNN NEGATIVE LINEARITY
LNN=m Sets the installed 5D64’s negative lin-
earity adjustment to the value m (% of
actual midscale output reading), where
-2 ≤ m ≤ 2. A
positive LNN value moves
the negative-domain midpoint upwards
(yielding a smaller negative reading at
that point), while a
negative LNN value
moves it downwards (yielding a larger
negative reading).
LNN Reads current negative linearity adjust-
ment value; returns m in the format
X.XX.
LNP POSITIVE LINEARITY
LNP=m Sets the installed 5D64’s positive linear-
ity adjustment to the value m (% of
actual midscale output reading), where
-2 ≤ m ≤ 2. A
positive LNP value moves
the positive-domain midpoint upwards
(yielding a larger positive reading at
that point), while a
negative LNP value
moves it downwards (yielding a smaller
positive reading).
LNP Reads current positive linearity adjust-
ment value; returns m in the format
X.XX.
MID MODULE IDENTIFICATION
MID Reads the installed 5D64’s current ID
and diagnostic information string.
Returns
5D64,xxxx,hhhh (where
“xxxx” is the module’s 4-character
alphanumeric
Serial Number, and
“hhhh” is the 4-character hexadecimal-
ASCII error code).*
NOTE: There is no “write” form of the
MID command.
MIO MODULE INPUT OFFSET
MIO=m Sets the installed 5D64’s pre-amplified
(analog input) offset to the value m (%
of selected full-scale input range—see
RNG, below), where –20 ≤ m ≤ 20.
MIO Reads current module input offset
value; returns m in the format XX.XX.
MP0 through MPD MODULE PARAMETER
Used by the 3000PLUS CONFIGURATOR software to
write and read miscellaneous module configuration
information, as follows (each
MPn string $ can have
up to 16 ASCII characters;
spaces may be included
as desired or required.
NOTE: THE FOLLOWING
LIST INCLUDES ONLY THOSE “MP” COMMANDS
THAT ARE USED WHEN A 5D MODULE IS
INSTALLED INA 3000PLUS METER.

A.2 MODEL 5D64 SETUP AND
INTERROGATION COMMANDS
PLEASE NOTE: All of the 3000PLUS commands listed in this and the following section are applica-
ble when the installed 5D module is a Model 5D64 DC Voltage Conditioner. Valid commands
that only apply to other 5D models (and NOT to the 5D64) are not listed here, and will evoke a
response of NAK when issued to a 3000PLUS instrument with an installed 5D64 module.
* For interpretation of the error code, see any 5D Module Instruc-
tion Manual
