OPERATION

71

Parallel Calibration

The parallel calibration function can be used
to offset cables losses.

External Voltage and Resistance Control

Voltage/Resistance controlled remote
control can only be used with the master
unit.

The full scale current (in parallel) is
equivalent to the maximum external voltage
or resistance.

Internal Resistance

For 2 units in parallel, the internal resistance
is actually half of the setting value.

For 3 units in parallel, the internal resistance
is actually a third of the setting value.

For 4 units in parallel, the internal resistance
is actually a fourth of the setting value.

See function setting F-08 for internal
resistance settings, page 101.

Bleeder Control

The Master unit is used to control the
bleeder settings. The bleeder resistors in all
the slave units are always turned off when
in parallel mode.
