Safety instructions
- Read the instruction manual carefully before operating the device! Keep for later reference.
- Mounting and installation must be carried out by suitably qualified and competent persons only.
- WARNING: The measurement inputs of the device can carry life-threatening voltages!
- WARNING: When working on the device hazardous voltages must not be connected to the device! The terminals J1-J6 are not isolated from the measuring circuit
- DANGER: When the USB port is connected, only voltages lower than 50 V may be applied to the measurement inputs. The USB port is not isolated from the measurement circuit.
- At the maximum current strength (10 A), 500 mW of waste heat is generated at the current sense resistor. The tip of the current sense resistor becomes very hot (87 °C). Maintain the appropriate safety distances and pay attention to good ventilation!
- 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 device in the presence of explosive or flammable substances!
- All cables carrying hazardous voltages must be secured with external separators.
Meaning of symbols
**** General warning sign
(Attention, observe the documentation!)
Intended use
- Measurement of current, voltage, and frequency in the specified measuring ranges.
- Indoor use is noncondensing and noncorrosive.
- Panel mounting.
- In operation, supply the device preferably via screw terminals with 12 to 24 V AC/DC instead of via USB.
- Failure to comply with these instructions will void all guarantees and warranties.
Description
The measurement types volt AC/DC, ampere AC/DC, frequency, and 5 A or 1 A for
current transformer are supported. The unit can be switched between different
measurement modes via an external switch. Minimum and maximum values are
recorded. They can be displayed and reset using an external switch. Measured
values are recorded over a time span of 36 seconds up to 14 days. The time
base as well as the display of the measuring history can be switched by an
external switch. The measured values remain stored as long as the device is
supplied with voltage.
With the additionally available USB interface the following parameters can be
adjusted using the configuration software “Digalox Manager”: scale endpoint,
scale caption, display style (pointer, tachometer, bar graph, and more),
splash image, and more. Recorded measurement values can be read and continuous
transmission of measurement values can be enabled. Using the software, values
can be viewed and exported as CSV files.

“Digalox® Manager”.

Mounting
Carefully insert the device into the panel cut-out. Insert the mounting
bracket from the back and push towards the panel until the device 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 an optional gasket (separately available).
Electrical connections
WARNING: The device may only be operated in one of the connection options shown above!
Configuration
The device can be configured via jumpers or using the additionally available
USB interface with the corresponding software “Digalox®
Manager”. When configuring via jumpers the basic settings can be made. The
configuration via USB allows full functionality.
Configuration via jumpers
Select measurement mode with jumpers at J4-J6 according to table “measurement
mode”.
Table measurement mode (factory preset, can be changed by software)
| Measurement mode| Display| Selection
---|---|---|---
1| V AC direct| Volt AC|
2| An AC direct| Ampere AC|
3| V DC Direct| Volt DC|
4| A DC Direct| Ampere DC|
5| AC Frequency| Freq. Hz|
6| 5A AC scaled (current transformer)| Ampere CT|
7| 1A AC scaled (current transformer)| Ampere CT|
To configure the upper scale caption, connect J3 within 10 seconds after
restarting and disconnect it again. The device switches to programming mode.
“Prog” appears in the display, followed by the upper scale caption, whereby
the digit to be changed is shown as “x”. Use J2 to select which digit is to be
changed. Change the value of the digit with J1.
Connect J3 again to save.
If the measurement mode “5A AC scaled” or “1A AC scaled” is selected the upper
scale caption must correspond to the primary value of the current transformer
for correct scaling of the measured value.
Configuration via USB interface with software “Digalox® Manager”
Connect the device and the computer using a USB cable. The device driver is
installed automatically if the computer is connected to the Internet.
After restart, the device always shows the first display value or the one
that is selected by the jumpers J4-J6 (see table “measurement mode”).
Other settings
The following functions can be activated independently during operation by
short-circuiting connectors J1-J3, e.g. using a jumper or switch:
J1: Graphical historic data display
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 (1, 3, 6, 12, 24, 48,
72), minutes (3, 15, 30) or seconds (36). The time base can be changed by
alternately opening and closing J1 (interval < 2 sec). When first opening and
closing J1 the current ime base is displayed. For each subsequent opening and
closing the time base changes to the next setting.
J2: Min-Max display
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
The device automatically changes the upper scale caption depending on the
current measuring value between 10, 100 and the set upper scale caption.
Maintenance
Periodically check all external cable connections.
Cleaning
Observe the safety instructions before cleaning the device. Clean the device with a dry lint-free soft cloth. Do not use solvents.
