2. Safet instructions
Note: The measurement inputs of the device can carr 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 onl protective device or protective
shutdown.
Read instruction manual carefully before o erating the device!
The device is not intended to rotect ersons or facilities against harm. S ecific
devices must be used to guarantee safety ( rotection 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 exam le, when measuring 250 V AC switches must be isolated for
at least 500 V.
Do not o en the housing!
Do not use the instrument in the resence of ex losive or flammable substances!
All cables carrying hazardous voltages must be secured with external se arators.

3. Description
The measurement modes volt AC/DC, am ere AC/DC, frequency and 5 A current
transformer are su orted. Scale end oint of the indicator as well as scaling of the
analogue signal and current transformer measurement can be adjusted freely via the
DIP switch, alternatively the o tion for automatic ada tion of the scale end oint can
be used. The unit can be switched between volt and am ere measurement via an
external switch. Minimum and maximum values are recorded and can be dis layed
o tionally using an external switch. Measured values are recorded over a time s an
of 3 minutes u to 14 days. The time base as well as the dis lay of the measuring
history can be activated by an external switch. The measured values remain stored
as long as the device is su lied with voltage.

5. Configuration
The device can be configured via DIP switches and jum ers.
Scaling
In modes where a scaling is necessary to re resent the correct measurement value
(for exam le 5 A AC for current transformer) the u er scale value corres onds to
the rimary value of the current transformer.
Exam le: u er scale value = 50 = rimary value of the current transformer
Configuration via DIP switches and jumpers if onl one measurement mode is
required (Manual mode)
1. Set DIP switch 10 to ON osition.
2. Set measurement mode with jum ers at J4-J6 according to table "Measurement
mode”, column “Manual mode".
3. Set u er scale ca tion for the first measurement mode with DIP switches 1-9
(see “Configuration of the u er scale ca tion”).
4. Connect su ly voltage.
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 su ly voltage.
2. Set DIP-switch 10, 11 and 12 to OFF osition.
3. Set the measurement mode with jum ers at J4-J6 according to table
"Measurement mode”, column “Save mode".
4. Set DIP switch 10 to ON osition.
5. Set u er scale ca tion for the first measurement mode with DIP switches 1-9
(see “Configuration of the u er scale ca tion”).
6. Set time base for gra hical historic data dis lay (o tional, see “Other settings”).
7. Set DIP switch 10 to OFF osition.
8. "Saved” a ears on the dis lay. The configuration of the first measurement
mode is now com leted.
9. When using multi le measurement modes re eat ste s 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 o eration 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 u er scale ca tion is binary coded using DIP switches 1-9. Possible values are
1 to 500. Switch 1 corres onds to 256, switch 2 corres onds to 128, switch 3
corres onds to 64, etc., switch 9 corres onds to 1. For configuration, roceed as
follows:
1. Connect su ly voltage.
2. Set DIP switches 1-9 to OFF osition.
3. Set DIP switch 10 to ON osition.
4. Start with 1st switch.
5. Set switch to ON osition.
6. If the dis layed value is greater than the desired value, set the switch back to
OFF osition.
7. If the dis layed value is less than the desired value, leave the switch in ON
osition and move on to the next switch.
8. Re eat ste s 5 to 7 until the desired value is dis layed.

6. Other settings
The following functions can be activated inde endently by short-circuiting
connectors J1-J3 by jum er or switch during o eration:
J1: Graphical historic data displa
To activate the gra hical historic data
dis lay connector J1 is shorted. The unit
dis lays the stored values within the set
time base as a gra hical 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 o ening and closing J1
(interval < 2 sec). When first o ening and
closing J1 the current time base is
dis layed. For each subsequent o ening
and closing the time base changes to the
next setting. In order to save the setting
ermanently, DIP switch 10 must be
switched from ON to OFF osition.
J2: Min-Max-displa
To activate the Min-Max dis lay connector
J2 is shorted. The dis lay shows the
maximum and minimum values recorded
since the last reset. The values can be
reset by o ening and closing connection
J2 shortly (interval < 2 sec). The dis lay
shows "Minmax reset".
J3: Auto scaling
To activate auto-scaling J3 connector is
shorted. The device automatically
changes the u er scale ca tion
de ending on the current measuring value
between 10, 100 and the set u er scale
ca tion.

7. Mounting
Carefully insert the instrument into the anel cut-out. Insert the mounting bracket
from the back and ush towards the anel until the instrument sits tight. Make sure
the mounting bracket is sna ed into the side of the housing. To ensure IP65
rotection (dust and water jet) when mounting in a front anel, use o tional gasket
(se arately available).
