5.4. A/D Converter Performance Test
The scale performance test should be performed before you install the bus connection. The tests are linearity,
repeatability and eccentricity. You can follow the test at the virtual display and/or status tab which show the
measurement data, the instrument data and the software version. For convenience keys for Taring, Zeroing
and Clear are located in this tab.
5.5. Bus Interface Setup
FAD-30 instruments have a bus interface and these parameters have to be setup before the bus will be
connected. Bus communication settings are done in the Gateway tab.
Bus communication parameters and their descriptions can be found in the related instrument chapters.
Gateway Information:
Gives the user info about
the bus interface
Communication setup:
Network parameters
Load Defaults: Loads the
default values
Refresh: Reads the
settings from the instrument
and updates the window
Write to Converter: Saves
and activates the settings to
the instrument
Find on Network: Search
for the instrument on the
network

5.6. Bus Addressing via Setup Switch
The bus addressing of FAD-30 instruments is done by the xFace software (Refer to chapter 5.3.1). The
alternative way for addressing is the setup switch on the front panel for addresses between 0 and 7 for RS-485,
Modbus RTU, Profibus and CANopen interfaces. This feature gives you the practical advantage for addressing
the instrument up to address 7 without requiring a PC connection.
For addressing via the setup switch, press this switch for 5 seconds. Then the status LEDs indicate the bus
address as shown in the table below. If the address is higher then 7 all LEDs are flashing. The address can be
changed by pressing the setup switch sequentially. To save and exit, press the setup switch for 5 seconds. To
return to normal operation without saving, wait 15 seconds without pressing the switch.

5.7. Back up Settings and Calibration Data
The parameter settings and the calibration coefficients can be saved to a backup file after reading these data
from the FAD-30 instrument. This backup file can be re-written to FAD-30 after opening it by xFace.
The backup feature gives a service advantage to FAD-30 instruments. We propose to burn these files to CD /
DVD and save this backup CD / DVD in the control cabinet additionally to a backup file on your PC.
Important note: The previous parameter settings and calibration coefficients in FAD-30 will get lost after
loading a backup to the instrument.
