Basic calibration of Micropilot M FMR250 after exchange of antenna assembly
The antenna, the microwave module and the signal processing electronics with the parameter memory determine the characteristics of the
system and change the measuring properties of the device, when exchanged. Therefore, a basic calibration of the instrument is mandatory
after any exchange of modules. To perform a basic calibration, the complete instrument with antenna has to be taken out of the process
tank. It is advisable to fix the device in a clamp or test holder and to power it from an external power supply.
1
Unlock service matrix and customer parameters: in the group selection of the operating matrix,
select level "diagnostics" and enter code 300 in the "unlock code" field (matrix position 0A4).
2
In the operating matrix group selection --> system parameters--> field "distance unit" set the
as desired, to either meters or feet (matrix position 0C5).
3
In the service matrix group selection --> service --> mapping --> field "factory map valid"
select 2 = reset (matrix position 0D34). Any existing factory map will be deleted.
4
In the service matrix group selection --> service --> antenna table --> field "antenna type"
(matrix position 0D81) select the correct antenna.
5
In the service matrix group selection --> service --> antenna table --> field "
(matrix position 0D8 ) 2 enter the inactive length of the antenna
6
In the service matrix group selection --> service --> antenna table --> field "total length"
(matrix position 0D83) enter the total length of the antenna
7
In the operating matrix group selection --> extended calibration --> submenu selection
• common --> field "blocking distance"
8
Prepare recording of factory map: in the service matrix group selection
--> service --> mapping --> set field "factory map valid" to "on" (matrix position 0D34).
9
In the operating matrix group selection --> extended calibration --> select field "check distance"
and "4 = manual" (matrix position 051).
10
In the operating matrix group selection --> extended calibration --> submenu selection
• mapping field "range of mapping" (matrix position 052) enter the range to be mapped (max. range is
11
In the operating matrix group selection --> extended calibration --> field "start mapping"
(matrix position 053) activate mapping (the process takes a few seconds).
12
Electrical Z-distance (assumed from microwave module to antenna)
• Typical values of Z-distance dependeing on antenna type:
Antenna extension
Horn antenna
without/250 mm/450 mm
Parabolic antenna
• Procedure to determine exact Z-distance:
Position at a defined distance (e.g. 5.00 m) a metal reflector (e.g. metal sheet).
13
In the service matrix in the group selection --> service --> info --> field "unfiltered distance"
(matrix position 0D04) read measured value and calculate. Enter newly determined Z-distance in
service level --> module in field "zero distance" (matrix position 0D72).
14
Install instrument into process. Recording of customer map: In the operat. matrix group selection
--> extended calibration --> field "start mapping" (matrix position 053) activate mapping
(the process takes a few seconds).
15
Lock the operating matrix in the group selection --> diagnostics --> field "unlock code" (matrix field 0A4)
enter 100.
After this procedure, all further set up steps have to be performed: full- / empty calibration, safety settings, linearization, etc.
