Basic Functions
Locking Panel Operations (Key lock)
The PWX750ML’s key lock function prevents you from accidentally changing the settings.
When the keys are locked (when the LOCK LED is lit), only the OUTPUT key is valid.
1
Configure all the settings, such as the output voltage and output cur-
rent, as necessary.
2
Hold down LOCK (SHIFT+LOCAL) until the LOCK LED in the display
area lights.
When the LOCK LED lights, the keys are locked.
To unlock the keys, hold down LOCK again (SHIFT+LOCAL) until the LOCK LED turns off.
Bleeder On/Off Feature
p.41
You can turn the bleeder circuit on and off. Turn the bleeder circuit off when you do not want
the internal bleeder circuit to sink output current. When you connect a battery, you can pre-
vent excessive electrical discharges by turning the bleeder circuit off.
When using master-slave parallel operation or series operation, use the same settings on all
connected units.
Depending on whether the breeder circuit is on or off, the sink current and the fall time of out-
put voltage when an external voltage sources connected will vary.
The sink current or fall time indicated here is a standard value.

Sink current from an external voltage source when the breeder is on and
off (When the voltage from the external voltage source is larger than the
set voltage)

WARNING
Risk of electric shock. Set the bleeder on/off setting to “on” before you touch the out-
put terminals. Even if you turn the output off or turn the POWER switch off, if the
bleeder on/off setting is set to “oFF,” the voltage that was present when the output
was on will remain at the output terminals.

1 Even when the breeder is on, the sink current decreases gradually at output terminal
voltages lower than this voltage. If the output terminal voltage is near 0 V, hardly any current
will be sunk even when the breeder is on.
