3. Description
The measuring modes analogue signal 0/4 to 20 mA and 60mV DC shunt are
supported. Scale-endpoint of the indicator as well as scaling of the analogue signal
and current transformer measurement can be adjusted freely via the DIP-switch,
alternatively there is an option for automatic adaption of the scale-endpoint. The
unit can be switched between volt and ampere measurement via an external
switch. Minimum and maximum values are recorded and can be displayed
optionally using an external switch. Measured values are recorded over a time
span of three minutes up to 14 days. The time base as well as the display of the
measure history can be activated by an external switch.
The following parameters can be adjusted using the SB-Software: Scale-
endpoint, scale-caption, display-style (pointer, tachometer, bar graph, and more),
splash display, thresholds for alarm output, hysteresis, and more. Recorded
measurement values can be read and a continuous transmission of the actual
measuring value can be enabled. sing the software, values can be viewed and
exported as CSV.

5. Configuration
The device can be configured via DIP switches and jumpers manually or with the
corresponding software “Digalox Manager” via SB interface. When configuring via
DIP switches and jumpers the basic settings can be made computer-independent.
The configuration with the software “Digalox Manager” allows full functionality.
Setting scale via DIP switch
In modes where a scaling is necessary to represent the correct measurement value
(for example 60mV DC for shunt or analogue signal) the upper scale value
corresponds to the primary value of the shunt or the maximum display value of the
analogue signal.
Example:
upper scale value = 250 = primary value shunt
upper scale value = 100 = maximum display value of analogue signal
Configuration via USB interface with software “Digalox Manager”
Visit www.digalox.com to download software “Digalox Manager”. For use with
software set DIP switch 10 to OFF position.
Please note that the measuring mode selected in "Digalox Manager" is displayed
only until the power supply of the DPM72 is interrupted.
Configuration via DIP switches and jumpers if onl one measurement mode is
required (Manual mode)
1. Set DIP switch 10 to ON position.
2. Set measurement mode with jumpers at J4-J6 according to table "Measurement
mode”, column “Manual mode".
3. Set upper scale caption for the first measurement mode with DIP switches 1-9
(see “Configuration of the upper scale caption”).
4. Connect supply voltage.
In further operation, the device alwa s shows the measurement mode,
which is set b the jumpers J4-J6 or the DIP switches 11-12 respectivel !
(see table "Measuring mode").

----- 5 -----
Configuration via DIP switches and jumpers if it is required to switch between
multiple measurement modes via an external switch (Save mode)
The required measurement modes are configured and saved sequentially.
1. Connect supply voltage.
2. Set DIP-switch 10, 11 and 12 to OFF position.
3. Set the measurement mode with jumpers at J4-J6 according to table
"Measurement mode”, column “Save mode".
4. Set DIP switch 10 to ON position.
5. Set upper scale caption for the first measurement mode with DIP switches 1-9
(see “Configuration of the upper scale caption”).
6. Set time base for graphical historic data display (optional, see “Other settings”).
7. Set DIP switch 10 to OFF position.
8. "Saved” appears on the display. The configuration of the first measurement
mode is now completed.
9. When using multiple measurement modes repeat steps 2-8 until all required
measurement modes are configured. The time base must not be set again, as it
is used for all measurement modes.
10. In operation the measuring modes can be changed with a switch at J4-J6
according to table "Measurement mode”, column “Save mode".
Configuration of the upper scale caption
The upper scale caption is binary coded using DIP switches 1-9. Possible values are
1 to 500. Switch 1 corresponds to 256, switch 2 corresponds to 128, switch 3
corresponds to 64, etc., switch 9 corresponds to 1. For configuration, proceed as
follows:
1. Connect supply voltage.
2. Set DIP switch 10 to ON Position.
3. Set DIP switches 1-9 to OFF position.
4. Start with 1st switch.
5. Set switch to ON position.
6. If the displayed value is greater than the desired value, set the switch back to
OFF position.
7. If the displayed value is less than the desired value, leave switch to ON position
and move on to the next switch.
8. Repeat steps 5 to 7 until desired value is displayed.
