WARNING: If this instrument is not installed and used in accordance with these
instructions, the protection provided 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 reach 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.
CAUTION: Connect only one input signal range to the meter. Hazardous signal levels may be
present on unused inputs.
CAUTION: The isolation rating of the input common of the meter with respect to the option
card common and to the Logical Functions common (if used) is 250 Vrms and 500 Vrms with
respect to AC Power (terminals 1 and 2 of connector CN1). To be certain that the ratings are
not exceded, these voltages should be verified by a high-voltage meter before wiring the meter.
CAUTION:
1. Where possible, connect the neutral side of the signal (including current shunts) to the input
common of the meter. If the input signal is sourced from an active circuit, connect the lower
impedance (usually circuit common) to the imput signal common of the meter. (pin 1 CN2)
2. For phase to phase line monitoring where a neutral does not exist, or for any other signal input
in which the isolation voltage rating is exceeded, an isolating potential transformer must be
used to isolate the input voltage from earth. With the transformer, the input common of the
meter can then be earth referenced for safety.
3. When measuring line currents, the use of a current transformer is recommended. If using
external current shunts, insert the shunt in the neutral return line. If the isolation voltage
rating is exceeded, the use of an isolating current transformer is necessary.

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.

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 19999, 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
DPM3-E Electrical User Manual, 1st Edition
will be able to take a value in the range -19999 to 19999, 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.
Input Configuration
The figure below shows the input configuration menu. Divided into four submenus, each one
of them separated by the dotted line in the manual, each menu corresponds to the programming
of the different types of input: Volt dc, Volt ac, Amp dc, Amp ac. Once the type of signal has
been selected you have then to select the range. Usually the 100, 60, 50mV (nU) ranges are
shunts signals. .

Scaling
For linear signals, scaling 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.

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 personalised code. We recommend
changing the code set at factory and to write down your personalised 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 totLC=1, but it won t 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 (SEt 1). If present in meter.
• Relay 2 configuration (SEt 2). If present in meter.
• Input configuration (InPut).
• Display (diSP).
• Display color (CoLor).
• Relay setpoints value (SPVAL). If present in meter.
• Analog output configuration (Anout). If present in meter.
• Logic inputs configuration (LoGIn).
• Direct access to MAX. and MIN values (MAHMn).

Relay Configuration
Introduction
Some DPM3 models are equipped with either 2 relays that can provide individual alarm and
control capabilities. All relays 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)

Analog output
Introduction
Some DPM3 models include an analog output (4-20 mA).
The output is optoisolated with respect to the signal input and the power supply.
The meter provides a two terminal connector [(+ ) and (-)] that drives out a signal variation
from 4mA to 20mA proportional to a user-defined display range.
The signal can be used to transmit display information to a variety of terminal equipment such
as graphic recorders, controllers, remote displays or other devices that accept input data in
analog form.
The display values producing the full scale output (OUT-HI and OUT-LO) are introduced via
front-panel buttons in the same programming module.
The output signal can be set up for reverse action by programming the low display for the high
output (OUT-HI) and the high display for the low output (OUT-LO).
