INPUTS
Accuracy 0,2% f.s. ±1digit.
Sampling time 120msec for
temperature sensors, configurable for
linear inputs down to a minimum of
15msec with reduction of the resolution
to 4000 steps.
Configurable decimal point position for
linear inputs, for TC, RTD, PTC and
NTC inputs, only one decimal digit is
allowed in the maximum display range
of -199.9 to 999.9, with indication of
open circuit thermocouple or RTD, PTC
or NTC in open or short circuit,
indication of over- and under-range for
linear inputs.
