KROHNE MAGCHECK EN - Manual (Page 18)

18 MagCheck
point is +10m3/h.
With Non-IMoCom converters zero must be entered manually. Set function 1.3 Zero set to 000.000
with unit acc. setting of converter. To find a correct zero setting for the calibration test, step to Menu
1.4 Simulation. Set simulation value to 000.0%. Read indication from converter display. If indication
is too noisy, increase time constant of converter to 10s.. 30s. Wait 10 time constants, until indication
is stable. Read indication on converter display, enter read value with inverted sign into menu
Function 1.3 Zero Set.
Example:
Indication is -0.13 m3/hr.
Enter + 0.13 m3/hr (select sign by using
↑↓) into Function 1.3 Zero Set.
Back to menu 1.3 Zero setting by pressing
↵.
3.4.3 Function
1.4 Simulation
Press → key.
Entering a value here will simulate flow by creating a precise calibrated flow signal as input signal
for the converter. The outputs of the converter follow this calibrated flow signal level.
The simulated flow value may be set between –999.9% and +999.9% of the full scale as set or read
under "Function 1.2 Full Scale Value". For normal tests, setting shall be within
± 100.0%.
If the maximum signal level of MagCheck is exceeded, the warning "error message: simulation
parameters, check" is shown on the MagCheck display.
Back to menu 1.4 Simulation by pressing
↵.
