Current input models have a special parameter, C13, which allows you to choose the type
of current input: C13=0 for 4/20 mA probes, factory-set value, and C13=1 for 0/20 mA
probes. The value is therefore to be modified only if a 0/20 mA probe is being used.
The same C13 parameter is used by thermocouple input instruments:The value C13=0,
factory-set, corresponds to thermocouples type K, C13=1 to thermocouples type J.The
value of C13 is therefore to be modified only if you require thermocouples type J.
Current/voltage inputs instruments have two special parameters, C15 and C16, which allow
the user to define the working range of the actual probe, and which are the values
corresponding to minimum (C15 parameter) and maximum (C16 parameter) input. C15
and/or C16 parameters must be modified only if the probe limits are different from the
factory-set ones: C15=0 and C16=100.
C13, C15 and C16 parameters can be modified as follows:
a) press the “5” and “6” keys sim
ultaneously for 5 seconds;
b) the display shows 0;
c) select the password, by pressing the “7” key until 22 is displayed;
d) press the “5” key to confirm the password;
e) if the selected password is correct, code “C0” will be displayed, otherwise you will have
to repeat procedures from point a);
f) press the “7” and/or “8” keys until the desired parameter is displayed (C13, C15 or C16):
then press the “5” key;
g) the value associated to the parameter is displayed: press either “7” or “8” keys until the
desired value is displayed; press “5” to confirm;
h) repeat procedures from point f) to modify other parameters or press the “6” key to exit
the procedure.
