Device test The device test comprises the following
menu item 2.4 test components:
S
Self test , menu item 2.4.1
The self test routines are inserted in the current measurements and
are completed after about 60 seconds. If there is no error, ”OK” is
displayed, otherwise ”not OK”. The type of error can then be read
out in the menu item ”
2.1 Device status”.
S
Display test , menu item 2.4.2
The LCD is checked with this menu item. The display is initially dark
for approx. 5 seconds and then bright for approx. 5 seconds.
Simulation flow The flow can be simulated in a range from
±
110 %.
menu item 2.5.1 Here you also have the possibility of checking displays, totalizers, limit
values and outputs in certain measuring ranges. The running simulation
is indicated by a flashing ’F’. It ends at the end of a previously set
period or after entering the ’End’ parameter in this menu item.
Simulation outputs With this function you can check the signal circuits of the analog
menu item 2.5.2 output, the digital outputs 1 and 2 as well as the flow.
2.5.3 In the individual menu items, you select the value to be simulated with
2.5.4 the and operating elements. You activate the setting by confirm•
ing the selected value with the operating element. The running
simulation is indicated by a flashing ’F’. You end simulation of the
output signal by actuating the
operating
element (exit the menu item). Digital output 1 must be configured for
the ”Alarm” function for simulation of the alarm signal (setting in the
menu item ”
4.2.1 Function”).
5.3.3 Function Group Measuring Functions
Flow You have the following setting options in this menu:
menu item 3.1
S
Engineering unit , menu item 3.1.1
This function offers you the possibility of choosing between units of
volume flow (volume unit per time) or mass flow (mass unit per
time). If a unit of mass is selected, it is mandatory to enter the
density of the medium in menu item
3.1.4.
