Package contents: Panel meter Digalox DPM72, 5 × jumpers, 1 × mounting bracket

1. Intended Use

 Indoor use non condensing, non corrosive.
 Panel mounting.
 Failure to comply with these instructions will void all guarantee and warranty.
 In operation, supply the device preferably via screw terminals with 10 to 24 V

AC/DC. If the device is supplied via USB in operation, USB supply voltage must
be at least 5 V.

2. Safety instructions
 Note: The measurement inputs of the device can carry life-threatening

voltages!

 When working on the device hazardous voltages must not be connected to

the device!

 The device must not be used as the only protective device or protective

shutdown.

 Read instruction manual carefully before operating the device!
 The device is not intended to protect persons or facilities against harm. Specific

devices must be used to guarantee safety (protection relays, cut-off switches,
etc.).

 When connecting switches to the terminals J1-J6, only switches must be used

whose isolation voltage is at least twice the maximum occurring measurement
voltage. For example, when measuring 250 V AC switches must be isolated for
at least 500 V.

 Do not open the housing!
 Do not use the instrument in the presence of explosive or flammable substances!
 All cables carrying hazardous voltages must be secured with external separators.

3. Description

The multi display with RGB backlight is able to display up to 4 parameters
simultaneously. Thresholds can be associated with individual warning backlight
colours. The unit can be switched between measurement modes via an external
switch. Minimum and maximum values for each parameter are recorded and can be
displayed optionally using an external switch. Measured values of one parameter are
recorded over a time span of three minutes up to 14 days. The time base as well as
the display of the measuring 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, backlight colour, thresholds for alarm output, threshold warning colour (light,
blink), hysteresis, and more. Recorded measurement values can be read and a
continuous transmission of up to four measuring values can be enabled. Using the
software, values can be viewed and exported as CSV file.

Warning:

The device may only be operated in one of the connection options shown
above!
Current measurement on the high side (between plus and load) only for
voltages up to 50 V!
In this case the entire device is on high potential. Particularly to be considered
when connecting switches to J1-6.
