6.4.1.2. Selecting and scaling the analogue output quantities
Disconnect the security lock jumper!
ASEL xxx yyy
xxx = channel 1's quantity
yyy = channel 2's quantity:
RH
= relative humidity
T = temperature
Td = dewpoint temperature
Abs = absolute humidity
Mix = mixing ratio
h = enthalpy
Tw = wet bulb temperature
Example: relative humidity selected on channel 1 and temperature on channel
