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 ?
