Description
The ProSense DPM2 series offers a simple, low cost digital display of analog process signals,
temperature in either Fahrenheit or Celsius from RTD or Thermocouple temperature sensors,
or potentiometer inputs. The 4-digit 14mm character height red LED display is easily scaled
into any engineering units from -9999 to 9999 with a selectable decimal point location. The
DPM2L offers a larger 20mm character height scaled from -1999 to 9999. Two point direct
or reverse acting linear scaling values can be entered manually or by introducing actual sensed
process values in Teach mode. Temperature inputs are pre-configured for fixed temperature
ranges based on the type of temperature sensor and can be displayed with 1 or 0.1 degree
of resolution. One model includes two SPDT relay outputs that can be set to activate on
an increasing or decreasing input signal with hysteresis or time delay operation. The meter
is powered from an external wide range AC or DC power supply and provides 24VDC for
external sensor excitation. The 1/8 DIN housing is easy to install in a panel and the meter
face has an IP65 rating. Configuration parameters can be totally or selectively locked out to
prevent unauthorized or accidental changes to the meter’s operation. Additionally, the DPM2
meters include memory and reset of minimum and maximum display values. ProSense digital
panel meters are backed by a 3 year warranty.

Installation
To install the instrument, prepare a 92mm x 45mm
panel cut-out and slide the unit inwards making sure
to place the sealing gasket between the front side panel
and the front bezel.
While holding the unit in place, put the fixing clips on both sides of the case and slide them
through the guide tracks until they reach the panel at the rear side.
Press slightly to fasten the clips to the latching slots on the case and get the unit fully assembled
and close fitted to achieve a good seal.
To remove the instrument from the panel, pull the rear fixing clips latching tabs outwards until
they are disengaged, then slide the fixing clips back over the case.

Refer to the instructions in this manual to preserve safety protections.
WARNING: If this instrument is not installed and used in accordance with these
instructions, the protection provided by it against hazards may be impaired.
To meet the requirements of EN 61010-1 standard, where the unit is permanently connected to
main supply, it is obligatory to install a circuit breaking device easily reachable by the operator
and clearly marked as the disconnecting device.
To guarantee electromagnetic compatibility, the following guidelines should be kept in mind:
• Power supply wires should be separately routed from signal wires and never run in the same conduit.
• Use shielded cable for signal wiring.
• Cables section should be ≥0.25 mm².
Before connecting signal wires, signal type and input range should be verified to be within the
right limits. Do not connect simultaneously more than one input signal to the meter.

Configuration
When the power is applied to the meter, a display test begins automatically to check the
function of LED’s and digits. Once this test is finished the display shows the internal software
version and then the unit goes to RUN mode.
Configuration follows a structure composed of a number of menus and submenus. By pressing
ENTER key, display shows “Pro”, pressing again allows access to the main menu level which
includes the menus for input configuration (InP), display configuration (dSP) and relay
setpoints configuration (SEtP) if relays are present in the meter.
If configuration has been totally locked-out, when pressing ENTER key to get into main menu,
display shows “dAtA” instead of “Pro”. This indicates that it is only possible to see programmed
information and that it is not allowed to modify any parameter from the entire configuration. In
this visualization mode, the meter automatically switches back to RUN mode after 15 seconds
since last key press.

ENTER:Vertical displacement / Validates data.
UP:Increases active digit value.
SHIFT:Horizontal displacement / Changes active digit.
Once inside each menu, all configuration parameters are sequentially shown and they can then
be introduced or edited by pressing ENTER key. Numeric values must be entered digit by digit,
by first selecting the digit using the SHIFT key and then changing its value with the UP key.
When the desired display value is reached, press the ENTER key to validate the data and move
forward to next configuration step.
Data entered or changed during configuration are stored in device memory only when
configuration routine belonging to the respective submenu is completed, not before. On last
routine step and after having pressed ENTER key, display indicates “StorE” and the unit goes
back again to RUN mode.
Input Configuration
The first menu corresponds to input configuration. This, in turn, consists of four submenus, one
for each input type: process (ProC), temperature (tEMP), potentiometer (Pot) and resistance
(rES).

THROUGH FRONTAL KEYS CONFIGURATION “SCAL”
Input and display values are configured manually through the
three keys of the instrument. This method is suitable when
signal values supplied by the transducer at each extreme point of
the process are known.
REAL INPUT SIGNAL CONFIGURATION “tEAC”
Input values are entered by introducing actual process values.
The input signal device must be connected to the meter at
the CN2 input connector and operational. Display values are
configured manually through the three keys, as in the previous
case. This method is suitable when signal values at each point are
unknown but, it is possible to drive the process to the conditions
defined by these extreme points.
WEIGHTED AVERAGE FILTER “FiLt”
Sets low-pass filter cutoff frequency (Fc) which allows the meter to smooth out undesirable

Display Scaling
Display scaling is necessary when adapting display reading to a particular engineering unit.
Display range can be configured between -9999 and 9999 for the DPM2 or -1999 to 9999
for the DPM2L.
Display scaling is a linear process that consists in introducing two input values, referred as
Input 1 and Input 2, and their respective display values, referred as Display 1 and Display 2.
On the basis of this proportional relationship internal software calculates display value that
would correspond to a given input value. Decimal point position is selectable and completes the
engineering units indication configuration.
It is possible to scale display in an direct acting (increasing) or reverse acting (decreasing)
proportional mode depending on whether the second display value (DISP.2) is greater or less
than the first (DISP.1). In an increasing mode, display value increases proportionally to the
input value whereas in a decreasing mode, display value decreases.

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
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.

Resistance Input
When programmed input type is resistance, the display can be manually scaled by selecting
(uSEr) or the display can be scaled to fixed calibrated ranges (CAL) depending on the resistance
range previously configured.
Display scaling is possible through frontal keys (“SCAL”)
and through real input signal (“tEAC”) as described for
process input. If the fixed calibrated range option “CAL” is
selected, the programming routine goes directly to the filter
configuration (“FiLt”) with no option to return to scaling
configuration.
Filter configuration is done in the same way as described for
process input.
