Measurement Commands
The measurement commands are used to read information on the statistical cal-
culations and for reading the most recent measurement for a specified channel.
CALCulate:AVERage:CLEar
Resets all running statistics for both channels.
Example: CALC1:AVER:CLE
This command may be password protected (see Section 8.2.10, Password
Commands).
CALCulate<chn>:DEWPoint?
Returns the dewpoint measurement on the specified channel in degrees C or F.
Example: CALC1:DEWP?
Response: 3.5
The CALCulate suffix, <chn>, specifies the channel (1 or 2). The value re-
turned is always in the current temperature units (C or F).
CALCulate<chn>:HINDex?
Returns the heat index calculation for the specified channel in degrees C or F.
Example: CALC1:HIND?
Response: 28.4
The CALCulate suffix, <chn>, specifies the channel (1 or 2). The value re-
turned is always in the current temperature units (C or F).
CALCulate<chn>:PARameter<num>:AVERage<type>?
Returns the specified statistical calculation for the specified channel.
Example: CALC1:PAR1:AVER4?
Response: 25.186
The CALCulate suffix, <chn>, specifies the channel (1 or 2). The PARamenter
suffix, <num>, specifies temperature (1) or relative humidity (2). The AVER-
age suffix, <type>, specifies the statistic: average (1), standard deviation (2),
minimum (3), maximum (4), spread (5), maximum rate (7), or alarm count (8).
Temperature values are in the current temperature unit, C of F.
CALCulate[<chn>]:PARameter[<num>]:AVERage[<type>]:CLEar
Resets all of the running statistics for both channels.
This is the same as the CALCulate:AVERage:CLEar command (see Section
