Saving Reference Values (Characteristic Parameters)
B.I.V. (BUILT-IN VERIFICATOR)
BIV, abbreviation for Built In Verificator, is available as option for SE58 L transmitters and must be enabled by
the manufacturer. It is also necessary that the SD card is activated to store saved data. The analysis of collected
data performed by a dedicated software running on another device (PC).
The simplicity of test procedures minimize the risk of handling errors; maximum safety and reliability thanks to
the traceable factory calibration and internal references complement the safety by design principle with minimal
failure rates
Please contact the manufacturer for detailed information and support.
After sensor installation, the parameters that will be used as reference for the BIV system and the IsoBIV data
analysis software must be measured.
The characteristic values of the coil circuits are saved in the transmitter memory at the factory before to ship
the device. For the reference measure of the electrodes circuits, there is a specific function that perform the
measures of voltage and resistance at the installation site. This function is managed ONLY by the IsoBIV
program, which through a simple wizard will set the transmitter to perform the measures in the specific
measurement point where the meter is installed.
To activate BIV, these functions must be verified:
[ASVFE=1] : This command enables hourly the sensor’s automatic test. The ASVFE command in Menu 1 with
access level 3 can be also activated using the device’s display.
This feature can be enabled even if the SD card is not installed and if the BIV function is not active; in such
a case the sensor file is NOT created and any alarms will be generated either if the data deviation from the
reference data is outside the sesnor’s limits.
Practically, in the absence of the necessary hardware permissions, this function is useful to test the insulation of
the coils.
