Device Description
These models in the ProSense DPM1 series offers a simple, low cost digital display of analog
process signals. The 4-digit red LED display is easily scaled into any engineering units from
-1999 to 9999 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 16 scaling points.
Two SPST relay outputs are included that can be set to activate on an increasing or decreasing
input signal with hysteresis or time delay operation. Models are also available with a 0-20mA
or 4-20mA analog output. The meter is powered from an external AC or DC power supply
and provides 20VDC for external sensor excitation. The 1/32 DIN housing takes up minimal
panel space 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.

Programming Keys
ENTER: Enters configuration and
validates data and parameters.
UP: Increases value of blinking digit in configuration
mode.
SHIFT: Selects mode or shifts blinking digit in
configuration.
(Bottom View)
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 for <3 seconds, the main menu level is entered and the display will show “Pro”.
Pressing the SHIFT key provides access to the programming menu level which includes menus
for input configuration (InP), display configuration (dSP), relay configuration if present (SEt),
analog output configuration if present (A.out). Press ENTER to access the submenus under
each programming 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 from the last key press.

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 -1999 to 9999, 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 -1999 to 9999, without taking into account the decimal
point.
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. Stor 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.

Scaling
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.
display2
display1
input 1
Input2
Direct scale
input 2
input 1

Reversed scale
In nonlinear processes it is possible to program up to 16 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.
Input
Display
1 2 3 4 5
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 point 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.

DPM1 User Manual, 1st Edition

15
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 16, 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 (0.4 Hz to 0.004 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.

Additional Functions
Several functions can be controlled via the Key Pad that will produce different actions depending
on the instrument operating mode:
TARE and Reset TARE functions
To configure the meter for Tare mode, press the UP key while in RUN mode and the meter 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, pressing the UP key again will
add the currently displayed value to the previously stored tare value resulting in a new stored
tare value. To reset the tare value to zero, press the UP key for 3 seconds while in RUN mode.
The TARE Led will turn off and the displayed value will be the gross value (without the tare).
MAX/MIN function
With the meter in RUN mode: Activated after pressing the SHIFT key for less than 3 seconds.
From RUN mode, a press shows the maximum value read by the instrument since the last time
it has been switched on, unless a RESET MAX/MIN is done, the display will alternate between
“Hi” and the maximum stored value. With a second press the display will alternate between
“Lo” and the minimum stored value. A third press brings the instrument back to RUN mode.
Reset MAX/MIN
While the meter shows the peak value (MAX), pressing the SHIFT key for 3 seconds will
produce a reset of the value. Pressing SHIFT key for 3 seconds while the meter shows the valley
value (MIN) will produce a reset of the value.
Configuration Lockout
In mode RUN if the ENTER key is pressed for 3 seconds, the meter will show the indication
CodE, and following 0000, allowing the user to introduce the security code. If the code that
has been introduced is wrong, the meter will go back to RUN mode, if it is correct, it will
allow the access to the security menu. See section detailing Configuration Lockout.
Return to Factory Configuration
From RUN mode press the ENTER key for less than 3 seconds to access Pro programming
mode. Now press the UP key for more than 3 seconds to allow entering the numeric code to
reset the meter to factory configuration parameters. This code is 74. When entering this code
the meter shows the LoAdIng dEFAuLt ConFIGurAtIon, and then StorE, which means
that they have been stored in the non volatile memory of the meter.

Configuration Lock Out
The meter is delivered with the programming not locked out, giving access to all the
programming levels. Once completed the meter programming the following security measures
are recommended:
1. Lock out the programming access to prevent from programmed parameters modifications.
2. Lock out Key Pad functions to prevent from accidental modifications.
3. There are two lockout modes: selective and total. If the parameters are going to be readjusted
frequently, make a selective lockout. If no adjustment is going to be made, make a total
lockout. Key Pad functions lockout is always possible.
4. The access to the lockout routine is allowed by entering a personalized code. We recommend
changing the code set at factory and to write down your personalized code and keep it in a
safe place.
TOTAL LOCKOUT
The access to the programming routines to read data is allowed even if all parameters are locked
out ALL=Yes, but it will not be possible to enter or modify data. In this case, when entering
in the programming mode, the display shows the indication “-dAtA-”.
PARTIAL LOCKOUT
When only some parameters are locked out, all configuration data can be read but only non
protected parameters can be modified. In such case, when entering in the programming
mode, the display shows the indication -Pro- “.
Menus or submenus that can be locked out are:
• Relay 1 Configuration (C.SP.1).
• Relay 2 Configuration (C.SP.2).
• Relay 1 Setpoint Value (V.SP.1).
• Relay 2 Setpoint Value (V.SP.2).
• Input configuration (InP).
• Display (dSP).
• Analog output configuration (A.Out). If present in meter.
• Programming of the key TARE (tArE).
Lock-out menu diagram
The following figure shows the lock-out menu. The access to this menu is accomplished from
the run mode by pressing the ENTER key for 3 seconds, until the “CodE” indication appears.
The instrument is shipped from factory with the following default code: “0000”. Once this
code is entered, the “CHAn” menu is available to change to a personal code. Write down and

DPM1 User Manual, 1st Edition
User Manual - DPM1 Series Panel Meters
19
keep this code in a safe place (Do not count on your memory). This personal code makes the
default code useless.
If an incorrect code is entered, the meter will return automatically to the run mode. Total
lockout programming is achieved by changing ALL to Yes. Changing ALL to No will lead to
the selective lockout of the programming variables. Programming each one of the parameters
to 1 will active the lockout, if they are set to 0 programming will be accessible. Though the
programming is locked out, it remains possible to visualise the current programming.
The “Stor” indication informs that the modifications effectuated have been stored correctly.

Output Options
All output are optoisolated with respect to input signal and power supply.
Relay Configuration
Introduction
All DPM1 models with -2R option are equipped with 2 relays that can provide individual
alarm and control capabilities. Each relay can be configured to function based on independent
setpoint values within the full configured display range, time delay (in seconds), hysteresis (in
counts of display) and selectable HI/LO acting.
Description of Operation
The relay outputs activate when the display value reaches the corresponding programmed relay
setpoint value. The following relay operational parameters must also be set:
a. HI/ LO ACTING MODE.
In HI mode, the output activates when the display value exceeds the setpoint level and in LO
mode, the output activates when the display value falls below the setpoint
b. PROGRAMMABLE TIME DELAY or HYSTERESIS.
Each output action can be deferred by a programmable time delay or hysteresis level.
The time delay is the time that takes the output to activate after passing through the setpoint in
the up or down direction, while the hysteresis band will be selected asymmetrical i.e. only acts
on the output deactivation edge. The delay is programmable in seconds, from 0 to 99.
The hysteresis can be programmed, in counts, within the full display range. The decimal point
appears in the same position as programmed in the display configuration module.
The figures 1 and 2 show the time delay action (dly) and the hysteresis action (hys) of two
alarms (SET1 and SET2) programmed to activate in HI mode (OUT1) and LO mode (OUT2)
