SIMEAS-T - Transducer without auxiliary power
18
Calibration of the voltage transducer
Start value
Feed UE = 0.2 UEN ± 0.05% UEN, with trim potentiometer "min" set the output value
IA = 0.2 IAN ± 0.2% IAN.
Full-scale value
Feed UE = UEN ± 0.05% UEN, set the output end value IA = IAN ± 0.2% IAN with trim
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
EN = 0 to 0 to IAN
Start value
Feed UE = 0.8 UEN ± 0.05% UEN, set the output value IA = 0 + 0.1% IAN with trim
potentiometer "min".
Full-scale value
Feed UE = 1.2 UEN ± 0.05% UEN, set the output value IA = IAN ± 0.1% IAN with trim
potentiometer "max".
Check start and full-scale values, repeat calibration if necessary.
To set the potentiometer, refer to the previous schematic diagram.
