ASCL Scaling the analogue outputs

Disconnect the security lock jumper!

ASCL <cr>

Scales the outputs selected on channels 1 and 2.

For example, scaling relative humidity on the range of 0...100 %RH and tem-

perature -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>

The output scales can also be given directly with the ASCL command.

ASCL aaa.a bbb.b ccc.c ddd.d <cr>

aaa.a = lower limit of channel 1

bbb.b = upper limit of channel 1

ccc.c = lower limit of channel 2

ddd.d = upper limit of channel 2

For example, relative humidity is scaled to 0...100 %RH on channel 1 and

temperature to -40...+100 °C on channel 2:

>ASCL 0 100 -40 100 <cr>

Ch1 (RH) lo 0.000 %RH

Ch1 (RH) hi 100.000 %RH

Ch2 (T ) lo -40.000 'C

Ch2 (T ) hi 100.000 'C
