C1.1.1 Zero Calibration
Display of current zero value, continue with Query: calibrate zero? Select
with
or :
Break: return with
g
,
Automatic: continue with
g
, time counts down, displays actual value
when complete
Default:press
g
to set to factory-set zero value
Manual:continue with
g
display of last set value, use to set new
value (range -10... +10%)
(preferably use "Automatic“,Before calibration, set "zero“ flow in the
pipeline!)
C1.1.2 Zero Add Offset Direct input of a zero flow offset
C1.1.3 Pipe Diameter Set the pipe diameter in mm for the velocity calculation
C1.1.4 Flow Correction Defines additional correction for the mass flow range (-100...100%)
C1.2 Density
C1.2.1 Density Perform density calibration see section 10.5
C1.2.2 Density Mode Sel
Select From:
Actual: return with
g
Fixed: Use a fixed value for the density
Referred: Calculates the process density to a reference temperature
C1.2.3 Fixed Density Value Set the fixed density value
C1.2.3

C1.4 System Control
C1.4.1
Sys Ctrl
Function
Defines action of the process control. Select
• NO ACTION: OFF
• Flow and Total = 0: Force flow and all totalisers to zero
• Flow = 0: Force flow to zero
C1.4.2
Sys Ctrl
Condition Defines the condition for the process control function. Select either
DENSITY or TEMPERATURE
