RPT_STR?
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xxx
Returns the user report string. The user report string can be read on the Control Display
in local operation, and appears on calibration reports. (Sequential command.)
Parameter: None
Response: (String) Up to 40 characters
*RST
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xxx
(Reset Instrument command) Reset the 5500A Calibrator to the power-up state. *RST
holds off execution of subsequent commands until the reset operation is complete. This
command is the same as pressing the front panel R key.
A reset action evokes the following commands and values:
Command Value Command Value
STBY
(No output)
CUR_POST AUX
OUT 0V,0HZ EARTH OPEN
DC_OFFSET 0V LOWS TIED
DUTY 50PCT RTD_TYPE <RTD_TYPE_D value>
HARMONIC 1, PRI TC_OTCD ON
PHASE 0DEG TC_REF INT
RANGELCK OFF TC_TYPE <TC_TYPE_D value>
WAVE NONE,NONE TC_OFFSET 0 CEL
ZCOMP OFF TSENS_TYPE TC
SCOPE OFF OUT_IMP Z1M
TRIG OFF
Changes made to the setup menus that are not saved in memory are discarded on reset.
Response: (None)
Example: *RST
Place the 5500A Calibrator in a reset condition, evoking the commands and values
shown above.
RTD_TYPE
Overlapped CoupledIEEE-488 RS-232 Sequential
xx xxx
(Resistance Temperature Detector Type command) Set the Resistance Temperature
Detector (RTD) sensor type: pt385 (curve α=0.00385 ohms/ohm/°C) (default), pt3926
(curve α=0.003926 ohms/ohm/°C), or ni120 (empirical Curve for 120 Ohm Nickel
RTD).
Before using RTD_TYPE, select RTD using the TSENS_TYPE command. After using
RTD_TYPE, select the output temperature using the OUT command. Changes in
temperature sensors changes the output to 0 °C. Once set, the 5500A retains the RTD
type until power off or reset.
Parameters: PT385 (100-ohm RTD, curve α=0.00385 ohms/ohm/°C)
PT3926 (100-ohm RTD, curve α=0.003926 ohms/ohm/°C)
NI120 (120-ohm RTD, empirical curve)
Example: RTD_TYPE PT3926
Set the RTD type to a 100-ohm type, using the pt3926 curve
(α=0.003926 ohms/ohm/°C). The resistance of 100 ohms refers to the ice point
characteristic, (the resistance of the RTD at 0 °C (32 °F)).
