Temperature Input; Potentiometer Input - Automation Direct ProSense DPM2 Series User Manual

User Manual - DPM2 Series Process Panel Meters

Temperature Input

When programmed input type is temperature, thermocouple or Pt100 or Pt1000
sensor, the only parameter to configure is the filter and its configuration is done in the
FiLt
same way as described for process input.

Display scaling is not available for this input type, the unit then will assume a fixed
calibrated range depending on sensor type and previously configured units resolution

Potentiometer Input

When programmed input type is potentiometer, "tEAC" is the only method available to
perform display scaling.

In this case, it must be assured first that potentiometer is connected properly and
that it is not subjected to any external voltage.
After pressing ENTER key, the instrument analyzes connected potentiometer to
internally determine both maximum and minimum resistive values. Once this
calculation have finished, display shows "dSP1".
FIRST POINT DISPLAY VALUE:
dSP1: Display value indication.
0000: Value entered in counts within display range.
(potentiometer wiper must correspond to process first point).
DECIMAL POINT:
00.00:
Setting of decimal point position. (Decimal point can be located in
any position, and will be the same for Display 1 and Display 2. This
position remains fixed for all configuration steps and also for RUN
mode).
SECOND POINT DISPLAY VALUE:
dSP2: Display value indication.
0000: Value entered in counts within display range.
(potentiometer wiper must correspond to process second point).
WEIGHTED AVERAGE FILTER:
FiLt:
0 to 9 selectable for low pass
filter cut-off frequency.
