20 V and 50 V are auxiliary ranges and have a limited bandwidth.
20 V range typically 0.9 Mhz
50 V range typically 1.9 Mhz
2)
Conditions for accuracy: Module temperature is calibration temperature ±5 °C; humidity is 30 to 90 RH;
AC accuracy: the highest fi lter (2 Mhz) has to be activated. f = signal frequency in kHz.
for the 2 year accuarcy multiply all % of range and % of reading values by 1.5.
3)
2 MHz fi lter: exclusively Butterworth 60 dB/decade. Please consider possible bandwidth limitation of further components in the measuring chain, e.g. A/D cards or
signal conditioning mainframe
