The ‘ Tools ’ (‘ tooL ’) menu contains multiple configuration options of
the instrument.
• select at the ‘ Option 1 ’ (‘ out.1 ’) parameter the module type
installed at the ‘Opt.1’
(see section 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 calibration menu
for the analog output module. See section 2.2 for more informa-
tion about this menu and the calibration.
• the ‘ Steps ’ (‘ StEP ’) parameter allows to configure a defined
minimum step change on the reading. Reading will change in
steps of 1, 2, 5, 10, 20 or 50 counts.
• the ‘ Average filter ’ (‘ AVr ’) function allows to reduce reading
oscillations due to noisy signals, by applying a recursive filter on
the reading values. The strength of the recursive filter is a value
configurable between ‘0’ and ‘100’. Value ‘0’ means ‘filter dis -
abled’. Filter strength increases with the value. Increasing the fil -
ter strength, increases the response time of the instrument.
• the ‘ Offset reading ’ (‘ oFFS ’) parameter allows to configure a
fixed number of counts to be subtracted from the reading. Ac -
cepts values from -500 to 500. This function allows to compen -
sate for the possible error introduced by the resistance of the
signal wires when measuring Pt probes, Ni probes or resistances.

the parameter ‘420’ gives

more information.
• select parameter ‘ Decimal point 2 ’ (‘ dP.2 ’) to activate the decimal
point at position XX.XX
• select parameter ‘
Decimal point 3
’ (‘
dP.3
’) to activate the decimal
point at position 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 activated before will power off. When the external contact
opens, the previous decimal point powers on again while removing
the new decimal point. Display does not show in flash mode when
decimal point functions are activated.
• select parameter ‘
Second scaling
’ (‘
ScL.2
’) to activate the second
scaling configured at menu ‘
Tools
’ (‘
TooL
’) \ ‘
Second scaling
’. The
activation of the ‘
Second scaling
’ function is accepted for all signal
input ranges based on AC input signals, DC input signals, process
and resistances. Display does not show in flash mode when second
scaling function is activated. For more information on the ‘
