Calibration and Operation
This chapter is concerned with the basic settings of the Silometer FMX 570 which allow
it to operate for continuous level measurement. The principle sections describe:
•
Commissioning
•
Calibration for level measurement
•
Calibration for linear volume or weight measurement
•
Dry calibration for Deltapilot probes
•
Level offset
•
Display of measured values
•
Locking the parameter matrix.
The linearization for volume or weight measurements is described in Chapter 5, the
setting of the analogue outputs in Chapter 6 and the controls in Chapter 3.
Note your settings!
When configuring, note your parameters in the Table in the rear cover.
•
If the transmitter is ever replaced, these parameters can be entered at the
front panel. The transmitter will then measure correctly without the need for
another calibration.
4.1
Commissioning
If programming the module for the first time, reset the module to the factory based
parameters, see Table in back cover. Then enter the probe constants fo and S (
∆
f). This
ensures that the EC 37 Z/EC 47 Z electronic insert or Deltapilot can be replaced without
the need for recalibration, see Section 7.3.

Operating mode
The operating mode is set at V8H0. Since the default value corresponds to level
measurement, this step can be omitted if the transmitter has been reset.
For a recalibration without reset check that mode 1, is on display:
•
1 = continuous level measurement, Sections 4.2, 4.3, 4.4.
•
6 = simulation, see Chapter 7, Section 7.2.
