POL POLARITY
POL=NO Sets the polarity of the meter’s limit-
zone relays to NORMALLY OPEN.
POL=NC Sets the polarity of the meter’s limit-
zone relays to NORMALLY CLOSED.
POL Reads current polarity setting; returns
NO or NC.
SEC SECURITY
SEC=n Sets the security code that must be
entered via the meter’s front panel
before any front-panel configuration
changes can be made (n is any four-
digit number between 0000 and 9999).
SEC Reads current security code number;
returns n.
SMD SENSITIVITY MODE
NOTE:
THIS COMMAND IS CURRENTLY RECOG-
NIZED ONLY BY A 3000PLUS WITH AN INSTALLED
MODEL 5D64 DC VOLTAGE CONDITIONER MODULE.
IT ONLY TAKES THE FOLLOWING “READ” FORM:
SMD Reads current sensitivity mode setting
for “ABSOLUTE TRANSDUCER” calibra-
tion (see Section 4.E of this manual);
returns 1 (for “VOLTS FULL SCALE”) or
2 (for “VOLTS PER UNIT”). This para-
meter is primarily for front-panel menu-
ing, and is not included in a 3000PLUS
configuration file.
TAR TARE
TAR=m Sets the tare offset for the meter’s
“auxiliary” DAC output (Channel 2) to
yield a reading of m when application
of the tare offset is enabled via logic-
signal input. The value m is expressed
in engineering units and to the decimal-
point precision of the current
FSU
value; -199990 ≤ m ≤ 199990; stores in
EEPROM memory the actual tare offset
required to yield a reading of m.
TAR Reads last-entered “tared” reading;
returns m.
APPENDIX A: MNEMONIC COMMANDS
CHN CHANNEL
CHNx Returns the current reading of the
meter’s Channel No. x, where x = 1 (for
the basic 5-VDC output, scaled to engi-
neering units), 2 (for the “auxiliary” DAC
output), or 3 (for the “scaled voltage”
output).
DIS DISPLAY
DIS=x Calls the meter’s Channel No. x to dis-
play (for channel numbers, see the
CHN command, above). Note that on
powerup, Channel 1 will be automati-
cally displayed.
DIS Returns the number of the currently
displayed channel (x).
HLD HOLD
HLD=ON “Freezes” the current values of Chan-
nel 2 (“auxiliary” DAC output) and
Channel 3 (“raw volts” output) until
receipt of a subsequent HLD = OFF
command or recycling of power.
HLD=OFF “Unfreezes” Channels 2 and 3, allowing
them to resume normal operation. The
meter will always power up in the HLD =
OFF state.
HLD Returns the current “hold status” of
Channels 2 and 3 (ON or OFF).
RLS RELEASE
RLS “Unlatches” any and all latched limits
for the meter’s “auxiliary” DAC output
(Channel 2), when limits mode and
latch mode are both ON (see the
LIM
and LAT commands, respectively).
