ASEL
Use the ASEL command to select the quantities and scaling for analog
outputs of the HMP155. Note that the optional quantities can be selected
only if they have been selected when ordering the device. Quantities and
their abbreviations are listed in Table 3 on page 11 and Table 4 on page
12.
ASEL [CH1 CH2] [low1 high1 low2 high2]
Where
CH1 = Quantity of channel 1
CH2 = Quantity of channel 2
low1 = Low limit of channel 1
high1 = High limit of channel 1
low2 = Low limit of channel 2
high2 = High limit of channel 2
Example 1 : To set the scaling of the outputs without changing the
quantities, enter the command without parameters. The probe will ask for
the limits. Note that ch0 is channel 1 and ch1 is channel 2.

Ch1 RH hi : 100.00 %RH ?
Example 2 : To set the output quantities of the channels, enter the
quantities as parameters. The probe will ask for the limits. Always
specify the quantities for both channels.

Example 3 : To set the quantities and scaling with a single command,
enter the quantities and limits as parameters according to the command
syntax.
