VALUE SIMULATION
PULSE
Prerequisite
The function is only available if COUNTDOWN was selected in the SIMULATION
PULSE function (ä 131).
Description
Use this function to specify the number of pulses (e.g. 50) which are output during the
simulation. This value is used to test downstream devices and the measuring device itself.
The pulses are output with the pulse width specified in the PULSE WIDTH function
(ä 128). The on/off ratio is 1:1.
!
Note!
The setting is not saved if the power supply fails.
Procedure
• Simulation is started once the specified value is confirmed with the
F
key. The
display remains at 0 if the specified pulses have been transmitted.
•If the
F
key is pressed again afterwards, the prompt "End simulation" (NO/YES)
appears.
• If you choose "NO", simulation remains active and the group selection is called up.
The simulation can be switched off again via the SIMULATION PULSE function.
• If you choose "YES", you end the simulation and the group selection is called up.
User input

ASSIGN STATUS Prerequisite
The function is only available if STATUS was selected in the OPERATION MODE
function (ä 122).
Description
Use this function to assign a switching function to the status output.
• The status output displays quiescent current behavior, in other words the output is
closed (transistor conductive) when normal, error-free operation is in progress.
• Pay particular attention to the illustrations and detailed information on the switching
behavior of the status output (ä 136).
• If you select OFF, the only function shown in this function group is the ASSIGN
STATUS function.
