Instruction Manual
2.2.1 Configuration menu
Configure at menu ‘Mode’ (‘ModE’) the output signal range to
‘
4/20
mA’ (‘mA’) or ‘
0/10
Vdc
‘ (‘
Vdc
’). Position for jumpers ‘V’ and
‘M’ must be according to the range selected.
At menu ‘Scaling’ (‘ScAL’) configure the values that define the two
points (‘high’ and ‘low’) of the ‘signal-reading’ slope:
• the lower slope point, defined by ‘Display low’ (‘d.Lo’) and ‘Out-
put low’ (‘Ao.Lo’)
• the higher slope point, defined by ‘Display high’ (‘
d.hI
’) and ‘Out-
put high’ (‘
Ao.hI
’)
Analog output values are shown with ‘XX.XX’ format, acceptable val
-
ues are ‘0.00’ to ‘10.00’
Vdc for voltage, and ‘0.00’ to ‘20.00’
mA for
current.
