DP20 Economical Multisignal meter Instruction Manual
The ‘Tools’ (‘tooL’) menu contains mulple conguraon opons of
the instrument.
• select at the ‘Opon 1’ (‘out.1’) parameter the module type
installed at the ‘Opt.1’ (see secon 2) slot. Select ‘relay’ (‘rELE’)
for the relay output module ‘A1’. Select ‘analog output’ (‘420’)
for the analog output module ‘M1’. Select ‘Modbus RTU’ (‘r.485’)
for the Modbus RTU serial output module ‘S1’.
Note : the parameter ‘420’ gives access to the calibraon menu for
the analog output module. See secon 2.2 for more informaon
about this menu and the calibraon.
• the ‘Steps’ (‘StEP’) parameter allows to congure a dened
minimum step change on the reading. Reading will change in
steps of 1, 2, 5, 10, 20 or 50 counts.
• the ‘Average lter’ (‘AVr’) funcon allows to reduce reading
oscillaons due to noisy signals, by applying a recursive lter
on the reading values. The strength of the recursive lter is a
value congurable between ‘0’ and ‘100’. Value ‘0’ means ‘lter
disabled’. Filter strength increases with the value. Increasing the
lter strength, increases the response me of the instrument.
• the ‘Oset reading’ (‘oFFS’) parameter allows to congure
a xed number of counts to be added to the reading. Accepts
values from -500 to 500. This funcon allows to compensate for
the possible error introduced by the resistance of the signal wires
when measuring Pt probes, Ni probes or resistances. For more

• select parameter ‘Decimal point 3’ (‘dP.3’) to acvate the decimal
point at posion X.XXX
Parameters ‘Decimal point 0’ (‘dP.0’)and similar ‘dP.1’, ‘dP.2’ and
dP.3’ control which decimal point is on. When the external contact
closes, the decimal point selected lights on and the decimal point
that was acvated before will power o. When the external contact
opens, the previous decimal point powers on again while removing
the new decimal point. Display does not show in ash mode when
decimal point funcons are acvated.
• select parameter ‘Second scaling’ (‘ScL.2’) to acvate the second
scaling congured at menu ‘Tools’ (‘TooL’) \ ‘Second scaling’. The
acvaon of the ‘Second scaling’ funcon is accepted for all signal
input ranges based on AC input signals, DC input signals, process
and resistances. Display does not show in ash mode when second
scaling funcon is acvated. For more informaon on the ‘Second
