3. Description
The measurement modes analogue signal and AC/DC shunt are supported
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 measured values remain stored as long as the
device is supplied with voltage
The following parameters can be adjusted using the USB software: scale endpoint,
scale caption, display style (pointer, tachometer, bar graph, and more), splash
image, 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 Using the software, values can be viewed and exported as CSV

Warning:
The device ma onl be operated in one of the connection options shown
above!
Current measurement on the high side (between plus and load) is
recommended onl for voltages up to 50 V!
In this case the entire device is on high potential. Particularl to be considered
when connecting switches to J1-6.
When measuring current, an external shunt must be connected to
measurement input U!

5. Configuration
The device can be configured via DIP switches and jumpers manually or with the
corresponding software “Digalox Manager” via USB 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
Scaling
In modes where a scaling is necessary to represent the correct measurement value
(for example 60 mV 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”
For configuration with software set DIP switch 10 to OFF position
Please note that the measurement mode selected in "Digalox Manager" is displayed
only until the power supply of the DPM72 is interrupted
In further operation, the device alwa s shows the measurement mode,
which is selected b the jumpers J4-J6 or the DIP switches 11-12
respectivel !
(see table "Measurement mode")
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
----- 4 -----

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 does not need to be set
again, as it is used for all measurement modes
10 In operation the measurement 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 switches 1-9 to OFF position
3 Set DIP switch 10 to ON 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 the switch in ON
position and move on to the next switch
8 Repeat steps 5 to 7 until the desired value is displayed

6. Other settings
The following functions can be activated independently by short-circuiting
connectors J1-J3 by jumper or switch during operation:
J1: Graphical historic data displa
To activate the graphical historic data
display connector J1 is shorted The unit
displays the stored values within the set
time base as a graphical trend
The time base can be set to days (7, 14),
hours (6, 12, 24, 48, 72) or minutes (3, 15,
30, 60)
The time base can be changed by
alternately opening and closing J1 (interval
< 2 sec) When first opening and closing
J1 the current time base is displayed For
each subsequent opening and closing the
time base changes to the next setting In
order to save the setting permanently, DIP
switch 10 must be switched from ON to
OFF position
J2: Min-Max-displa
To activate the Min-Max display connector
J2 is shorted The display shows the
maximum and minimum values recorded
since the last reset The values can be
reset by opening and closing connection
J2 shortly (interval < 2 sec) The display
shows "Minmax reset"
J3: Auto-scaling
To activate auto-scaling J3 connector is
shorted The device automatically changes
the upper scale caption depending on the
current measuring value between 10, 100
and the set upper scale caption

7. Mounting
Carefully insert the instrument into the panel cut-out Insert the mounting bracket
from the back and push towards the panel until the instrument sits tight Make
sure the mounting bracket is snapped into the side of the housing To ensure IP65
protection (dust and water jet) when mounting in a front panel, use optional gasket
(separately available)
