SIMEAS-T - Transducer without auxiliary power
Calibration of the voltage transducer
Start value
Feed U = 0.2 U ± 0.05% U
E EN
I = 0.2 I ± 0.2% I
A AN AN
Full-scale value
Feed U = U ± 0.05% U

potentiometer "max".
Repeat start and full-scale value calibration until the specified tolerances are achieved.
Calibration of the voltage transducer with suppressed start range and expanded
end range
Example: Transducer with range
0 to 0.8 to 1.2 U = 0 to 0 to I
EN
Start value
Feed U = 0.8 U ± 0.05% U
E EN
potentiometer "min".
Full-scale value
Feed U = 1.2 U ± 0.05% U
E EN
potentiometer "max".
Check start and full-scale values, repeat calibration if necessary.
To set the potentiometer, refer to the previous schematic diagram.
