Performing simulations and tests

The simulation tools, found in the Simulation menu under the Diagnostics menu, help confirm proper
communication of measured values. There are six standard simulations all performed in a similar way
(distance, level, ullage, interface, volume and flow). All are explained below.

Performing standard simulations

Standard simulations are performed by setting a value that you want to communicate and enabling the
simulation afterwards. The procedure below explains the procedure for level simulations, but a similar
method can be used for interface, distance and ullage simulations.
To perform a level simulation
1 Select Diagnostics > Simulation > Level Sim > Level Sim.
2 Press Edit.
3 Set the level value that you want to simulate and press OK.
4 Press Back.
5 Select Enable and press Edit.
6 Press OK.
The instrument sends level data signals on the network and the value set should appear as a reading
on a software communication tool interface.

Obtaining device status data

For commissioning purposes, you may need to gather data about the status of the instrument (probe
length, current electronics temperature [as well as minimum and maximum recorded] and total
instrument run time).

Probe length

NOTICE
Probe length confirmation can only be performed if the tank in which the probe is
installed is completely empty.
To confirm probe length:
1 Select Diagnostics > Device Status> Probe Length Status.
The probe length is indicated.
2 Press Back to return to the Device Status menu.
