Measurement uncertainty
Input FA
: +/- 1 Hz
Input VA
: +/- 1 Hz
Input TA
: +/- 1 (0.7 % of measured value + 0.02 % FS)
Temperature display
: +/- 1 Kelvin
Analog input 0-10 V
: +/- 1 (0.3 % of measured value + 0.02 % FS)
Analog input 4-20 mA
: +/- 1 (0.3 % of measured value + 0.02 % FS)
Input Pt100
: +/- 0.2 Kelvin
Analog output 1+2, 0-10 V
: +/- 1 (0.2 % of measured value + 0.02 % FS)
All values apply for a set damping rate of 30 seconds during measurement. In addition, the measurement
uncertainty of the utilised sensors must be taken into consideration.
