Specifying the MIN, MAX, or DEF parameter returns the minimum, maximum, or
default value respectively.
CALCulate[<chn>]:PARameter<num>:RESolution <num>|MIN|MAX|DEF
Sets the display resolution.
Example: CALC:PAR2:RES 2
The PARameter suffix, <num>, specifies either temperature resolution (1) or relative
humidity resolution (2). The <num> parameter specifies the number of decimal places to
use. Specifying the MIN, MAX, or DEF parameter sets the display resolution to the
minimum, maximum, or default value respectively. This command may be password
protected (see Password Commands).
FETCh? [<chn>]
Returns a comma-delimited list of the most recent measurements for the specified
channel or for both channels.
Example 1: FETC? 1
Response: 25.576,29.30
or
Response: 1,1,25.629,C,29.32,%,2003,9,16,11,2,38
Example 2: FETC?
Response: 25.582,29.32,26.341,37.96
or
Response: 1,1,25.629,C,29.29,%,2,0,C,0,%,2003,9,16,11,1,42
The <chn> parameter is optional and specifies the channel (1 or 2). If the <chn>
parameter is omitted, the most recent measurements on both channels are returned. If a
channel is disabled or no sensor is connected, the measurement values returned for that
channel are 0. This command does not affect the measurement action.
If the extended format setting is OFF (see FORMat:TDST:STAT), the measurement
values are returned in a comma-delimited format as follows:
<Ch1Temp>,<Ch1Humid>[,<Ch2Temp>,<Ch2Humid>]
The temperature values are always in the current temperature units. The humidity values
are always in %RH.
If the extended format setting is ON, the measurements are returned in a comma-
delimited format as follows:
<MeasStatus>,<ChX>,<ChXTemp>,<TempUnits>,<ChXHumid>,%[,<ChY>,<ChYTem
p>,<TempUnits>,<ChYHumid>,%],<year>,<month>,<day>,<hour>,<minute>,<second>
The measure status (<MeasStatus>) is 0 if these measurement values have been read
previously or 1 if these are new measurement values. If no channel number was specified,
the measurements on both channels are returned (X = 1; Y = 2). Otherwise, only the
measurements on the specified channel are returned. If only new readings are desired, the
FORM:TDST:STAT command can be used to enable the extended format option and any
readings in which the value of the first field is 0 can be ignored.
