Selecting the generated power supply
The device supplies for a specified time (
programmable warm-up time using
from 1 [default] to 32 seconds
) a DC voltage on PS+ pin
of the terminal block. The value of the DC voltage can be selected using J12 (
Errore.

):
DC voltage generated for a specified time:
24Vdc @ 100mA
DC voltage generated for a specified time:
12Vdc @ 100mA (
default
)

Jumper positions
Removing jumper J10 (
Errore. L'origine riferimento non è stata trovata.
), voltage generation on pin PS+ of the terminal block is disabled. This situation
may be useful in case the DC voltage is not necessary. Consequently, the battery life is increased.

Full-scale setting
The measurement’s full
-scale selection, is done positioning a jumper on the proper strip:
0÷25mA input
(

0÷5Vdc input
0÷10Vdc input
0÷25Vdc input
