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 available on the HMP110D.

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.
