Set Analog Output Error Indication Level
If the device is malfunctioning, the analog output is set to a specified
level. This overrides the normal measurement output of the channel. The
default error level is 0 V, or another value predefined by the customer
when ordering the device. You can set the level using the AERR
command. This command is not in use in the digital-only HMP110 probe
option.
AERR [ch1 ch2] <cr>
where
ch1
=
Error level of the analog output for channel 1. The available
range depends on the output
mode (check with AMODE
command).
ch2
=
Error level of the analog output for channel 2. The available
range depends on the output
mode (check with AMODE
command).
Example (show present output modes):
amode
Ch1 output : 0 ... 1 V
Ch2 output : 0 ... 1 V
Example (check present analog output error level):
aerr
Ch1 error out: 0.000V ?
Ch2 error out: 0.000V ?
Example (set analog output error level to 1 V on both channels):
aerr 1 1
Ch1 error out: 1.000V ?
Ch2 error out: 1.000V ?
NOTE
The
error output value is displayed only when there are minor electrical
faults such as humidity sensor damage. When there is a severe device
malfunction, the error
output value is not necessarily shown.
