Specifying the MIN, MAX, or DEF parameter returns the minimum, maximum, or default value respectively.
CALCulate[<chn>]:PARameter<num>:RESolution <num>MINMAXDEF
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).

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
<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.
