HMP260 SERIES

Appendix 1: Serial commands HMP260-U017en-1.5

ASEL RH T <cr>

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

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

Ch2 (T ) lo -40.000 'C ? 0 <cr>

Ch2 (T ) hi +160.000 'C ? 100 <cr>

When the ASEL command is given on its own, the transmitter outputs its current

settings:

ASEL <cr>

Ch1 (RH) lo 0.000 %RH

Ch1 (RH) hi 100.000 %RH

Ch2 (T ) lo -40.000 'C

Ch2 (T ) hi +160.000 'C

The outputs and their scales can also be given directly with the ASEL command.

ASEL xxx yyy aaa.a bbb.b ccc.c ddd.d <cr>

xxx = channel 1's quantity

yyy = channel 2's quantity

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

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 temperature -

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>
