D) Synchronization of bridge power
The master unit (INT) provides slave units (EXT) with the synchronization signal for bridge power.
Settings such as bridge voltage, calibration value, filter, measurement range, bridge check
ON/OFF, and cable length compensation ON/OFF are effective in each amplifier unit.
E) Balancing for all units (1)
Hold down the switch for BAL for all units (1). You can execute the bridge check, cable length
compensation, and auto-balancing for all units in a case. For a bridge check and cable length
compensation, ON/OFF setting (selectable with dip switches) for each unit is also effective.
Auto-balancing is made for all amplifier units. This function is available for all amplifier units
installed in two or more cases, which are connected to each other with a synchronization cable.
To perform auto-balancing for one unit, press the BAL knob (4) for that unit.
F) Switch for application of calibration values to all units (2)
Hold down the switch to apply calibration value (2). A calibration value is set to all amplifier units.
This switch has priority over the calibration value application switch (14) in each amplifier unit
regardless of the position of the switch (+
•
-). This function is available for all amplifier units
installed in two or more cases, which are connected to each other with a synchronization cable.
To apply a calibration value to only one unit, use the calibration value application switch (14) in
each unit. Before doing so, confirm that the switch for applying the calibration value to all units is
set to OFF.
