ASCL
Scaling the analogue outputs

ASCL
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
Ch1
(RH) lo
0.000 %RH?
Ch1
(RH) hi
100.000 %RH
?
Ch2
(T ) lo
0.000 'C ?
-40
Ch2
(T ) hi
100.000 'C
?
160
The output scales can also be given directly with the ASCL command.
ASCL aaa.a bbb.b ccc.c ddd.d
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
Ch1
(RH) lo
0.000 %RH
Ch1
(RH) hi
100.000 %RH
Ch2
(T ) lo
-40.000 'C
Ch2
(T ) hi
100.000 'C
