Note
Contactors, high power electric motors, frequency drives and other power devices
should not be in a close proximity of the meter. Input signal leads (measured value)
should be seperated from all power lines and power devices. Even though the device
has been designed and tested according to standards for industrial environment, we
strongly advise to adhere to the above presented rules.

Note
There is galvanic connection between USB connector and input!
In case you need to configure the unit while the input signal is connected,
the use of a galvanic isolated OM USB-ISO convertor is recommended..

Analogue output range setting
. by a long press (>s) of the SET button enter the configuration mode - LED PWR yellow and LED SET turquoise
. connect the signal of the desired value for the minimum of the range AO to the input of the converter (for example mA)
. by a long press (>s) of the SET button this value is set - LED PWR yellow, LED SET purple
. connect the signal of the desired value for the maximum of the range AO to the input of the converter (for example , mA)
. by a long press (>s) of the SET button this value is set - LED PWR yellow, LED SET green
. by a short press of the SET button return to the standard working mode - LED PWR green
For a quick and simple set-up you can use the DIP switch
Tare settings
. by a short press of the SET button enter configuration of Tare - LED PWR white and LED SET turquoise
. by a long press (>s) of the SET button set the current value of Tare - LED PWR white, LED SET green
. by a short press of the SET button return to the standard working mode with active Tare - LED PWR green, LED SET white
iA short press at any time during the calibra-
tion will end the calibration without saving.
After one minute of inactivity, the calibration
is terminated without saving and both LEDs
return to the basic state

iSetting of Analogue output is active only
when DIP switches No. - are in the “”
position, i.o. Setting via OM Link
iMinimum range of Analogue output for U/I
inputs signals is pre-set as unipolar,
i.e. " V/mA" or " mA".
If required, it is also possible to enter a nega-
tive value of the maximum in the minimum,
i.e. zero will be in the middle of the selected
range.
