Use the ASEL command to show or set the output parameters and scaling of the analog outputs. This command is not in use in the digital-only HMP110 probe option.

ASEL [ch1 ch2] [ch1low ch1high ch2low ch2high]<cr>

Syntax Description
ch1

Output parameter for channel 1. The options are:

  • RH = Relative humidity
  • T = Temperature
  • Td = Dew point temperature
  • Tw = Wet bulb temperature
  • a = Absolute humidity
  • x = Mixing ratio
  • h = Enthalpy
ch2 Output parameters for channel 2. The options are same as for channel 1.
ch1low Low limit for channel 1 output scaling.
ch1high High limit for channel 1 output scaling.
ch2low Low limit for channel 2 output scaling.
ch2high High limit for channel 2 output scaling.

Example (show current output parameters and scaling):

asel ?
Ch1 RH lo : 0.00 %RH ?
Ch1 RH hi : 100.00 %RH ?
Ch2 T lo : -20.00 'C ?
Ch2 T hi : 80.00 'C ? 

Example (change channel 1 to output dew point temperature, adjust scaling to -40 ... 60 °C for channel 1 and to -20 ... 80 °C for channel 2):

asel td t -40 60 -20 80
Ch1 Td   lo    :   -40.00 'C
Ch1 Td   hi    :    60.00 'C
Ch2 T    lo    :   -20.00 'C
Ch2 T    hi    :    80.00 'C

Example (change channel 1 to output temperature and channel 2 to output relative humidity, adjust scaling for channel 1 to -40 ... 60 °C when prompted):

asel t rh
Ch1 T    lo    :   -20.00 'C ? -40
Ch1 T    hi    :    80.00 'C ? 60
Ch2 RH   lo    :     0.00 %RH ?
Ch2 RH   hi    :   100.00 %RH ?
