ACCURACY AT 25 ºC
see for each type of signal at section 11
*
accuracy values are indicated for 4/20 mA output. For
0/10 Vdc output, add +0.05 % to indicated accuracy
values.
THERMAL DRIFT
±100 ppm/ºC (F.S.)
±0.05 ºC/ºC (thermocouple cold junction)
STEP RESPONSE
Step response associated to the configured
power filter (see section 13.10). Typical response
values to reach 99% of the output signal, as a
response to a 100% step at the signal input (see
Table 30).
