Example (set channel 1 error level to 20 mA, channel 2 to 10 V):

aerr 20 10

Ch1 error out : 20.000 mA

Ch2 error out : 10.000 V

NOTE

The error output value is displayed only when there are minor electrical

faults such as a sensor damage. When there is a severe device

malfunction, the error output value is not necessarily shown.

Extend Analog Output Range

Use the AOVER command to allow the analog output channels to

exceed their specified range by 10%. The scaling of the parameter

remains as before; the extra range is used for additional measurement

range in the high end of the scale.

AOVER [ON/OFF]<cr>

Example:

aover on

AOVER : ON

The following example illustrates how the analog output is affected.

Channel 1 outputs T

with voltage output 0 … 5 V (-80 … -30 °C). After

giving the AOVER ON command, the range is 0 … 5.5 V

(-80 … -25 °C). Note that the -30 °C T

point is still at 5 V.
