Specifying the MIN, MAX, or DEF parameter returns the minimum, maximum, or

default value respectively.

CALCulate[]:PARameter:RESolution |MIN|MAX|DEF

Sets the display resolution.
Example: CALC:PAR2:RES 2
The PARameter suffix, , specifies either temperature resolution (1) or relative

humidity resolution (2). The 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? []

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 parameter is optional and specifies the channel (1 or 2). If the

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:
,[,,]
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:
,,,,,%[,,

p>,,,%],,,,,,
The measure status () 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.
