5.4.1.2 Selecting and scaling the analogue output quantities

Disconnect the security lock jumper!

ASEL xxx yyy <cr>

xxx = channel 1's quantity

yyy = channel 2's quantity (RH, T, Td, dT, Abs, Mix or Tw)

Example: RH selected on channel 1 and temperature on channel 2

>ASEL RH T <cr>

Ch1 (RH) lo 0.000 %RH? <cr>

Ch1 (RH) hi 100.000 %RH ? <cr>

Ch2 (T ) lo -40.000 'C ? <cr>

Ch2 (T ) hi +160.000 'C ? <cr>

5.4.1.3 Scaling the analogue outputs

Disconnect the security lock jumper!

ASCL <cr>

Example: relative humidity is scaled in the range 0...100 %RH and tem-

perature in the range -40...+160 °C

>ASCL <cr>

Ch1 (RH) lo 0.000 %RH? <cr>

Ch1 (RH) hi 100.000 %RH ? <cr>

Ch2 (T ) lo 0.000 'C ? -40 <cr>

Ch2 (T ) hi 100.000 'C ? 160 <cr>
