1. Description
•
5-digit digital display with analogue inputs and inte-
grated totaliser.
•
8 mm high, very clear LED display for easy reading.
•
Display range from -19 999 to 99 999 with leading
zero blanking
•
Programming of the functions or operating parame-
ters via the setting keys. Operating guidance via the
display while programming.

Programmable features:
Measuring range
Independent decimal point adjustment for the
momentary value display and the totaliser display
Displayed value for the lowest input signal
Displayed value for the highest input signal
Adding counter scale factor

no reset
Digital mains hum suppression (50 or 60 Hz)
2. Inputs
MPI
(Connect 4)
Multifunction input. Dependent to the setting of the re-
setting function, this input operates as LATCH or RE-
SET input (see 4.10).
In LATCH mode, the current value displayed is frozen,
while measurement and adding continue operating in
the background.
In RESET mode, the adding counter is reset to 0.
The input (PNP) is activated with an input signal of 4 ...
30 V DC. When falling below 2 V DC the input is inac-
tive.
CURRENT INPUT
(Connect 5)
Analogue current measuring input with reverse polarity
protection and current limitation to 50 mA maximum.
Connect here the signal wire.
Attention:
This input is electrically isolated to avoid
interference from the supply voltage. Thus, for the
measurement, the most negative measurement signal
wire is to be connected with the analog reference input.
ANLOGUE GND
(Connect 6)
When electrical isolation between the measuring loop
and the supply voltage is not required, connect 2 or 3
and this input (0V measurement signal) by means of a
bridge.
VOLTAGE INPUT
(Connect 7)
Analog voltage measuring input. Connect to pin 7 the
an signal wire. In case of a connection error,
the message „Err4“ is displayed.
Attention:
This input is electrically isolated to avoid
interference from the supply voltage. Thus, for the
measurement, the most negative measurement signal
wire is to be connected with the analog reference input .
3. Operating parameters adjustment
3.1 Switching between the display of the momentary
value and of the adding counter
The right key allows switching between the display of
the momentary measuring value and the value of the
adding counter.
Pressing this key once displays the active function („Act“
or „Tot“) for two seconds. If, during these two seconds,
the right key is pressed another time, the active function
is switched. This switching is confirmed by the display of
„Act“ or „Tot“ during approximately two seconds, and
then the device displays the value.
3. 2 Setting the operating parameters
a. Hold down both keys on front panel and switch on
the supply voltage.
b. The display shows
c.
After releasing the keys the display alternates
between menu title and corresponding menu item at
a frequency of 0.5 Hz. After any key is pressed, only
the menu item is displayed.
d. Pressing the right key, the menu item will be
switched to next value.
To input numerical values (e.g. when setting the
scaling factor), use the left key to select the decade
and the right one to set the value.
e. Hold down the left key and press the right key to
switch to the next menu title.
f.
After programming the last menu item, the program-
ming routine will be left and the new values will be
stored by switching the menu item to „YES“. If you
chose „NO“, the programming routine will be passed
through once again.
