Set Analog Output Parameters and
Scaling
Use the
ASEL
command to show or set the output parameters and the
scalings of the analog output.
ASEL
[
ch1
] [
ch2
]<cr>
where
ch1 = Parameter that is output on analog channel 1:. Available
parameters are TDF, TDFA, H2O, and P.
ch2 = Parameter that is output on analog channel 2. Available
parameters the same as for channel 1.
Example (show current settings):
asel
Ch1 Tdf lo : -60.00 'C ?
Ch1 Tdf hi : 40.00 'C ?
Ch2 P lo : 0.00 bara ?
Ch2 P hi : 10.00 bara ?
Example (change output parameters to TDFA and H2O and set scaling):
asel h20 ta
Ch1 Tdfa lo : 00.00 'C ?
-80
Ch1 Tdfa hi : 00.00 'C ?
20
Ch2 H2O lo : 0.00 ppm ?
0
Ch2 H2O hi : 0.00 ppm ?
500
Set Analog Output Error Notification
If the transmitter is malfunctioning, the analog output is set to a specified
level. This overrides the normal measurement output of the channel. The
default level is 0 mA or 0V, according to the output type. You can set the
level using the
AERR
command.
AERR
[
ch1
] [
ch2
]<cr>
where
ch1
= Error level for analog channel 1.
ch2
= Error level for analog channel 2.
Example (show current settings):
aerr
Ch1 error out : 0.000 mA ?
Ch2 error out : 0.000 V ?
