Description
The ProSense DPM2-E series offers a simple, low cost digital display of AC or DC voltage
or amperage electrical parameters. The 4-digit red LED display is easily scaled into any
engineering units from -9999 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 values in Teach mode. 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. 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-E meters include memory and reset
of minimum and maximum display values. 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 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,
first selecting digit and then changing its value. 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: DC voltage (UDC), AC voltage (UAC), DC current (AdC) and AC
current (AAC).

Display Configuration
The second menu corresponds to display configuration consisting of submenus according to
previously programmed input type.
FACTORY CALIBRATED RANGE “CAL”
Use the factory calibrated input range and display values
based on the Input Signal Type selected.
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 at each extreme point of
the process are known.
REAL INPUT SIGNAL CONFIGURATION
“tEAC”
Input values are entered by introducing actual electrical
parameter values. The input signal 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 reading
fluctuations.
Display Scaling
Display scaling is necessary when adapting display reading to a particular engineering unit. Display
range can be configured between -9999 and 9999.
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.

Additional Functions
MAX/MIN and RESET Functions
This device detects and stores in memory maximum and minimum values reached by the input
signal. This values are kept in memory although power supply is disconnected. When repeatedly
pressing SHIFT key, MAX/MIN function shows saved maximum and minimum values in
display since last RESET function activation.
In order to differentiate this value’s indication from RUN mode indication, decimal point
blinks while these values are shown. The unit automatically switches back to RUN mode after
15 seconds have elapsed since the last key press.
First SHIFT key pressing shows “MAH” in display followed by the maximum value, a second
pressing now shows “Min” followed by the minimum value and finally, a third pressing shows
“run” before returning to RUN mode.
RESET function is activated while visualizing maximum or minimum values and the SHIFT
key is pressed for at least 3 seconds. If maximum is the displayed value, current input signal
value will replace the previous maximum saved value. In the same way, current input signal will
replace saved minimum value while the minimum value is displayed.
Direct Access to Setpoints Value
If the DPM2 has relay outputs, it is possible to access setpoints
value configuration without having to enter main menu.
To access this submenu, from RUN mode ENTER key is
pressed, and then press UP key while “Pro” is displayed.
FIRST SETPOINT VALUE:
SEt1: Setpoint 1 value indication.
00.00: Value entered in counts within display range.
