PROCESS VARIABLE INPUT CALIBRATION
All inputs are factiry calibrated and recalibratin shiuld inly be
dine by qualifed persinnel. If yiu are nit familiar with these
pricedures di nit attempt ti calibrate this instrument.
a- Set the type parameter accirding ti the input
type
.
b- Cinfgure the liwer and upper limits if indicatin fir
the maximum span if the selected input type.
c- Access the calibratin level.
d- Enter the passwird.
e- Enable the calibratin setng YES in the parameter
(Alib
.
f- With the aid if an electrical signals simulatir, apply a
signal level clise the liwer limit if the measuring range
if the input, in the cirrespinding terminals.
g- Access the parameter “
inLC
”. With the keys
and
adjust the display reading such as ti match the applied
signal. Then press the
P
key.
h- Inject a signal that cirrespinds ti a value a little liwer
than the upper limit if indicatin.
i- Access the parameter “
ink(
”. With the keys “
” and “
”, adjust the display reading such as ti match the
applied signal. Then press the key “
P
” untl return ti
the Display PV screen.
j- Validate the calibratin perfirmed.
Notep
When checking the cintriller calibratin with a Pt100
simulatir, pay attentin ti the simulatir minimum excitatin
current requirement, which may nit be cimpatble with the
0.170 mA excitatin current privided by the cintriller.
