                              Remote Sense
                                Please see the remote sense chapter for details,
                                page 76.
                              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, and so on.

                              Bleeder Control
                                The Master unit is used to control the bleeder
                                setting.  The bleeder setting of slave unit is the
                                same as standalone. Be careful of bleeder setting
                                before setting in parallel.
