8.2.6.6 CALibrate<chn>:DATE:DUE (<year>,<month>,<day>)
Sets the sensor calibration due date for the specified channel.
Example: CAL1:DATE:DUE 2004,9,17
The CALibrate suffix, <chn>, specifies the channel (1 or 2). The <year>,
<month>, and <day> parameters must all be specified. The <year> parameter is
a four-digit number. The <month> parameter is a one or two-digit number (1 to
12). The <day> parameter is a one or two-digit number (1 to 31). This com
-
mand is password protected (see Section 8.2.10, Password Commands).
8.2.6.7 CALibrate<chn>:EXPired?
Returns the sensor calibration expiration state for the specified channel.
Example: CAL1:EXP?
Response: 0
The CALibrate suffix, <chn>, specifies the channel (1 or 2). A value of 1 is re-
turned if the sensor calibration has expired. A value of 0 is returned if the sen-
sor calibration has not expired.
8.2.6.8 CALibrate<chn>:PARameter:OFFSet<num>?
Returns the sensor calibration offset parameter for the specified channel.
Example: CAL1:PAR:OFFS2?
Response: -0.210
The CALibrate suffix, <chn>, specifies the channel (1 or 2). The OFFSet suf-
fix, <num>, specifies either temperature (1) or humidity (2).
8.2.6.9 CALibrate<chn>:PARameter:OFFSet<num> <float>
Sets the sensor calibration offset parameter for the specified channel.
Example: CAL1:PAR:OFFS2 -0.025
The CALibrate suffix, <chn>, specifies the channel (1 or 2). The OFFSet suf
-
fix, <num>, specifies either temperature (1) or humidity (2). The <float> pa
-
rameter specifies the value for the offset parameter. This command is password
protected (see Section 8.2.10, Password Commands).
8.2.6.10 CALibrate<chn>:PARameter:SCALe<num>?
Returns the sensor calibration scale parameter for the specified channel.
Example: CAL2:PAR:SCAL1?
Response: -0.564
The CALibrate suffix, <chn>, specifies the channel (1 or 2). The SCALe suffix,
<num>, specifies either temperature (1) or humidity (2).
