SIMULATION FAILSAFE
MODE
Description
Use this function to switch all inputs, outputs and totalizers to their error-response
modes, in order to check whether they respond correctly. During this time, the message
#691 "SIMULATION FAILSAFE" appears on the display (ä 67).

SIMULATION
MEASURAND
Description
Use this function to set all the inputs, outputs and the totalizer to their flow-response
modes, in order to check whether they respond correctly. During this time, the message
"#692 SIMULATION MEASURAND" appears on the display (ä 67).
!
Note!
• The measuring device can only be used for measuring to a certain extent while the
simulation is in progress.
• The setting is not saved if the power supply fails.

MEASURAND
Prerequisite
Function is only available if the SIMULATION MEASURAND function (ä 175) is
active.
Description
Use this function to specify an arbitrary value (e.g. 12 dm

/s) to check the assigned
functions in the device itself and downstream signal circuits.
The unit depends on the option selected in the SIMULATION MEASURAND function
and is taken from the associated function (UNIT VOLUME FLOW, UNIT
TEMPERATURE, UNIT MASS FLOW, UNIT PRESSURE, etc. (ä 102)).

Note!
The setting is not saved if the power supply fails.
