ACCURACY AT 25 ºC see for each type of signal at section 10
*
accuracy values are indicated for 4/20 mA
output. For 0/10 Vdc output, add +0.05 % to
indicated accuracy values
THERMAL DRIFT
±
150 ppm/ºC (F.S.) for ranges up to 5 mV
±
100 ppm/ºC (F.S.) for ranges up to 20 mV
±
75 ppm/ºC (F.S.) for ranges up to 80 mV
STEP RESPONSE
Response time according to the congured parameter ‘power lter’ (see section
13.9). Typical response times to reach 99% of the output signal, in response to a
100% step at the input.
