DPF20 Frequency, rate, total or period counter Instruction Manual
2.2.1 Conguraon menu
Congure at menu ‘Mode’ (‘ModE’) the output signal range to
‘4/20 mA’ (‘mA’) or ‘0/10 Vdc‘ (‘Vdc’). Posion for jumpers ‘V’ and
‘M’ must be according to the range selected.
At menu ‘Scaling’ (‘ScAL’) congure the values that dene the two
points (‘high’ and ‘low’) of the ‘signal-reading’ slope:
• the lower slope point, dened by ‘Display low’ (‘d.Lo’) and ‘Out-
put low’ (‘Ao.Lo’)
• the higher slope point, dened 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.

‘Er.34’ output signal congured to value lower than 0 Vdc or 0 mA
‘Er.35’ output signal congured to a value higher than 10 Vdc or 20 mA
‘Er.36’ congured slope points are not acceptable, such as :
‘d.Hi’=’d.Lo’
‘Ao.Hi’=’Ao.Lo’
(‘Ao.Hi’-’Ao.Lo’)>(’d.Hi’-’d.Lo’)
