SETTINGS "SECONDS FOR MEAN/MAX/MIN":
In the settings box "Seconds for ..." you set a value in seconds (max
30). According to the set value, the AVERAGE, MAX or MIN value will
be updated (for example every 10 seconds).
If the default value 0:
• Mean: The value is not averaged.
• Low: the absolute value is taken.
• MAX: the absolute value is taken.

This is the device configuration page where the alarm settings are set.
There are two types of selectable alarms, one with LED and the other
with contact (switch).
LED ALARM
Check for the presence of anomalies, the user can select to enable of
FAIL LED by checking one or more of the following flag:
FAIL EEPROM: Problem on the CONFIGURATION of the microproces-
sor (not calibrated module, does not hold the configuration).
INPUT UNDER RANGE / INPUT OVER RANGE: advise you when the
input value is UNDER or OVER of the set input. E.g. if we have an
Hall's Current probes +/- 1V, if the input value is +1,5V or -2V, you
see the LED indication in the front of the device. It informs you about
potential SATURATION of the Current probes.
RTD OUT OF THE RANGE: RTD outside temperature scale
(-200 .. +600 °C for PT100).
RTD THIRD WIRE ERROR: Third wire not connected (R > 20 Ω).
SWITCH ALARM
Selecting the desired parameter in the dropdown menu, you set the
threshold and hysteresis value to activate the alarm on digital output.
The alarm is always active.
Depending on the choice of set DIGITAL OUTPUT alarm contact the
device behaves as follows::
• If set to the NO contact, the alarm is above the threshold, with
negative hysteresis.
• If you set the NC contact, the alarm is below the upper threshold
with positive hysteresis.
This is the device configuration page on which the power input settings
are set.
TRANSDUCER RATIO: Set the transformer ratio..
If the input is 1A / 5A or 20mA / 100mA ist → f the current transfor-
mer ratio M / N
Example:
TA 600: 5 → Transducer ratio = 120
TA 1000: 1 → Transducer ratio = 1000
If the input is 1V, 10V ist → 1 / Sensitivity [V / A]
Example:
Probe 100mV / 1KA → Transducer ratio = 10000
Probe 4V / 400A → Transducer ratio = 100
MINIMUM STARTUP CURRENT: serves to set the minimum read
current.
DC FILTER: Number of tenths of seconds for the RMS calculation in
DC. This parameter sets the response speed of the machine into DC.
The higher the number, the more precise and slow the calculation in
DC.
AC FILTER: Number of zero-crossings for the calculation of the RMS
AC. This parameter set the response speed of the AC machine. The
higher the number, the more precise and slow the calculation in AC.
