Device Description
The ProSense DPM3 series offers a simple, feature packed digital display of analog process
signals, temperature in either Fahrenheit or Celsius from RTD or Thermocouple temperature
sensors, load cell, or potentiometer inputs. The 5-digit tri-color red, green or amber LED
display is easily scaled into any engineering units from -19999 to 39999 with a selectable
decimal point location. Two point direct or reverse acting linear scaling values can be entered
manually or by introducing actual sensed process values in Teach mode. Additionally non-
linear processes can be scaled by entering up to 11 scaling points. Models are available with
two SPDT or four SPST relay outputs that can be set to activate on an increasing or decreasing
input signal with hysteresis or time delay operation. Additionally the display color can be set
to change on relay operation. Models are also available with a 4-20mA analog output. The
meter is powered from an external AC or DC power supply and provides both 24VDC and
10VDC 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. Other
features include memory and reset of minimum and maximum display values, three tare
functions, display hold function, filtering to minimize display bounce, and display brightness
adjustment. ProSense digital panel meters are backed by a 3 year warranty.

Configuration:
When the power is applied to the meter, a display test begins automatically to check the function
of the 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
the ENTER key, the display show “Pro”. Pressing the SHIFT key repeatedly provides access
to the main menu level which includes menus for input configuration (CnInP), display
configuration (CndSP), relay configuration if present (SEtP), analog output configuration if

present (Anout), logic functions configuration (LoGIn). Press ENTER to access the submenus
under each main menu.
If configuration has been totally locked-out, when pressing ENTER to access the main menu
level, the 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 sine the last key press.

Programming Key Pad
The progress through the programming routines is done by pressing ENTER key. In general,
push SHIFT key a certain number of times to select an option and push ENTER key to validate
the change and move forward to the next step of the program.
Programming numerical values
When the parameter is a numerical value, the display will show the first of the digit to be
programmed blinking.
Digit selecting: Press repeatedly the SHIFT key to shift from left to right over all the display
digits.
Changing the digit value: Press repeatedly the UP key to increase the value of blinking digit
until it has the desired value.
The minus sign is programmed depending on the variable type. A variable that represents the
value of an input will be able to take a value in the range -19999 to 99999, without taking into
account the decimal point. When a digit is selected it shows values from (0) to (9), and then
(-1), (-), and comes back to show values from 0 to 9. A variable that represents a display value
will be able to take a value in the range -19999 to 39999, without taking into account the
decimal point. In these case the first digit shows 0, 1, -1, 2, 3 or -.
Completion of each submenu routine returns the meter to Pro mode. To save data entered or
changed during configuration press the ENTER key while in Pro mode. StorE will be displayed
for a few seconds while all of the configuration data is stored in memory. The meter will then
return to RUN mode.

Process input
The DPM3 is designed to measure all kinds of process variable with direct indication in
engineering units.
The parameter to configure as process indicator is the input type, in volts in a -10 V to 10 V
range and in milliamperes in a -20 mA to 20 mA range.
Load cell input
Refer to cell manufacturers documentation, particularly with respect to the cell sensitivity and
supply voltage specifications.
As load cell indicator the meters function is to measure forces (weight, pressure, torque...) when
connected to several bridge type transducers such as load cell, which supply signal levels up
to ±150 mV. The excitation voltage supplied by this instrument is 10V. Up to 2 cells can be
connected in parallel with 10 V excitation without need for an external source.
Example:
2 cells with 2 mV/V sensibility are supplied with an excitation voltage of 10 V; the
voltage generated by each cell at full load is 20 mV, being 20 mV the maximum as the
cells are connected in parallel.
Configuration requires selection of the input range which may be selected high enough for the
maximum input signal to avoid overloads. There are three ranges: ±15 mV, ±30 mV and ±150
mV
Example:
If a weighing process gives 12 mV to the meter input with maximum load, the best input range
to select will be “15 mV”.
Pt100 RTD Input
When configuring the meter as thermometer for 3 wires Pt100 sensors, the temperature ranges
and resolution available are:
Input Range (res. 0.1°) Range (res. 1°)
Pt100 -200.0 to +800.0°C -200 to +800°C
-328.0 to 1472.0°F -328 to 1472°F
The Pt100 software menu allows selection of temperature units (Celsius or Fahrenheit),
resolution (degree or tenth of degrees) and a display offset. Offset value is programmed for a
known difference between the temperature under measurement and the temperature read by the
sensor. This difference can be corrected by programming an offset from -19.9 to +99.9. LED
TARE will light up each time that an offset value is programmed.
Example:
In a process of temperature control the Pt100 sensor is located in a part of the process
where temperature is 10 degrees below than the point where the control has to be done. By
programming an offset of 10 points, with 1 degree resolution, the deviation will be corrected.
Configurable parameters for this input are:

DPM3 User Manual, 1st Edition
User Manual - DPM3 Series Panel Meters
16
A) Reading units in degree Celsius “ºC” or Fahrenheit “ºF”.
B) Resolution in tenth of degrees “0.1º” or in whole degrees “1º”.
C) Offset. The instrument comes from factory with offset=0
After entering these parameters, the display range and linearization are adjusted automatically.
Thermocouple Input
When configuring the meter for thermocouple input, the temperature ranges and resolution
available are:
Input Range (res. 0.1°) Range (res. 1°)
Thermocouple J -150.0 to +1100.0°C -150 to +1100°C
-238.0 to +2012.0°F -238 to +2012°F
Thermocouple K -150.0 to +1200.0°C -150 to +1200°C
-238.0 to +2192.0°F -238 to +2192°F
Thermocouple T -200.0 to +400.0°C -200 to +400°C
-328.0 to +752.0°F -328 to +752°F
Thermocouple N -150.0 to +1300.0°C -150 to +1300°C
-238.0 to +2372.0°F -238 to +2372°F
The thermocouple menu allows selection among several types of thermocouples, temperature
units (Celsius or Fahrenheit), resolution (degree or tenth of degrees) and a display offset. Offset
value is programmed for a known difference between the temperature under measurement and
the temperature read by the sensor. This difference can be corrected by programming an offset
from -19.9 to +99.9. LED TARE will light up each time that an offset value is programmed.
Example:
In a process of temperature control the thermocouple sensor is located in a part of the process
where temperature is 5 degrees below than the point where the control has to be done. By
programming an offset of 5 points, with 1 degree resolution, the deviation will be corrected.
Configurable parameters for this input are:
A) Thermocouple type [J, K, T, N].
B) Reading units in degree Celsius “°C” or Fahrenheit “°F”.
C) Resolution in tenth of degrees “0.1°” or in whole degrees “1°”.
D) Offset. The instrument comes from factory with offset=0
After introducing these parameters, the display range and linearization for the selected
thermocouple input are adjusted automatically.

Scaling
It is only necessary to scale the meter when it has been configured for a process or a load cell
input signal. When configured for temperature sensor input the meter is automatically scaled
to a fixed range based on the temperature sensor. Scaling consists of assigning a display value to
each input signal value.
In linear processes it is achieved by programming two coordinates (InP1, DSP1) and (InP2,
dSP2), between which is established a linear relation where each input signal value corresponds
to a display value. The relationship can be direct or reversed. In order to obtain more accuracy,
points 1 and 2 should be located approximately at both extremes of the process.

Reversed scale
In nonlinear processes it is possible to program up to 11 input to display points. Each two
points are connected by a straight line and the whole is a curve that represents the relationship
between the input value and the display value.

In order to obtain more accuracy it is recommended to program the highest possible number
of points and reduce the segment length. Input values must always be programmed in an
increasing or decreasing order. Avoid assigning two different display values to two equal
input values. Display values can be entered in any order and even be repeated for different
inputs.
Below the first point programmed, the relationship established between the two first points of
the scale is followed. Above the last point programmed, the relationship established between the
two last points of the scale is followed.
Programming of the scale
There are two methods for programming the scale, the SCAL method and the tEACH
method.

SCAL method
The input and display values are programmed manually. This method can be used when the
value of the signal supplied by the transducer at each points of the process is known.
tEACH method
The input values are introduced directly from actual process values. The input signal device
must be connected to the meter and operational when each point is programmed. The display
values are programmed manually. This method can be used when it is possible to bring the
process to the conditions of each one of the points to be programmed.
Programming of a nonlinear process
Access the first two input-display points by pressing the ENTER key. To access the programming
of the rest of the points, press ENTER key for 3s after entering the display value of point 2.
From here the progression is achieved by pressing ENTER key. When enough points have been
programmed to define the process, press ENTER for 3s after entering of the last DSP n value,
to get out of the scale programming routine. The rest of the points, up to 11, that have not been
programmed are omitted from the display calculation.

Accessible from the SCAL or tEACH menu, following the first display point. Once accessed, it
will start to blink in its present position. Use the SHIFT key to shift to another position.
The selected decimal point location will be applied to all display points and if present relay
setpoints and analog output scale.
Weighted Average Filter P
0to 9 (4Hz to 0.05 Hz)
Sets low-pass filter cutoff frequency (Fc) which allows the meter to smooth out undesirable
display reading fluctuations. The value can be modified through the SHIFT key. This parameter
will set in reverse order the cut-off frequency of the low pass filter, getting the filter deactivated
for 0 value. Not available when the instrument is configured for temperature measurement.
Round
01 05 10
Will take each one of the values by pressing successively on the SHIFT key. with 01 there will
be no round, 05 will round the display value at 0 to 5, and with 10 will round at 0 to 10. Not
available when the instrument is configured for temperature measurement.

Additional Functions
Several functions can be controlled via Key Pad that will produce different actions depending
on the instrument operating mode:
TARE and Reset TARE functions
Three different tare modes are available in the DPM3 and their functions are described below.
The desired tare mode can be selected in the Display Configuration CndSP / ModtA menu.
tare 1
To configure the meter for Tare 1 mode, select tArE1 under the ModtA menu in Display
Configuration CndSP. After saving the Tare 1 mode configuration and returning to RUN
mode, pressing the UP key will store the currently displayed value as the tare value (unless it is
over scaled) and the TARE Led will light. From this point the value displayed on the meter is
the net value, i.e., the measured value minus the stored tare value. If a tare value has been stored,
