8.2.6.11 CALibrate<chn>:PARameter:SCALe<num> <float>
Sets the sensor calibration scale parameter for the specified channel.
Example: CAL2:PAR:SCAL1 0.002
The CALibrate suffix, <chn>, specifies the channel (1 or 2). The SCALe suffix,
<num>, specifies either temperature (1) or humidity (2). The <float> parameter
specifies the value for the scale parameter. This command is password pro
-
tected (see Section 8.2.10, Password Commands).
8.2.7 System Commands
The system commands are used for querying instrument identification parame
-
ters, temperature units, and for setting operating parameters to the defined de
-
fault values.
8.2.7.1 *IDN?
Returns the instrument identification string that indicates the manufacturer,
model number, serial number, and firmware version.
Example: *IDN?
Response: HART,1620,A39001,1.00
8.2.7.2 *OPT?
Returns a list of sensor models currently connected to the inputs.
Example: *OPT?
Response: “2626-S”,"0"
The model number of the sensor connected to input 1 is reported first. The
model number of the sensor connected to input 2 is reported second. If no sen-
sor is connected to an input, the model number is reported as “0". The sensor
model numbers are enclosed in quotes and separated by a comma.
8.2.7.3 *RST
Sets the instrument settings to defined conditions.
Example: *RST
The following parameters are set when this command is issued.
•
Sets the measurement period to 2 seconds.
•
Sets the measurement averaging on.
•
Sets printing to the serial port
•
Sets the temperature units to C.
•
Sets the temperature resolution to 2 decimal places and the relative hu
-
midity resolution to 1 decimal place.
