Lock Settings
Pressing the LOCK key digitally locks the set voltage and current limit. The settings are stored with
a precision of better than 1 digit. Subsequent adjustments of the VOLTAGE and CURRENT
controls will have no effect.
Because cancelling LOCK will cause the output settings to change if the VOLTAGE and CURRENT
control positions have been moved, warning reminders are given before LOCK is cancelled. Press
and hold the key to cancel LOCK.
If the OUTPUT is off (the safe condition) the display will flash the 'unlocked' settings twice before
the change is implemented; the LOCK lamp goes off.
Releasing the LOCK key at any time while the display is flashing will abort the LOCK cancellation.
Attempting to select a different range with LOCK enabled is not allowed; if attempted, the message
is shown briefly in the display and the LOCK lamp is also flashed. If the output is also on

The LOCK function of the Master operates exactly as described previously and, because the
output voltage of the Slave tracks the Master, it controls the Slave output voltage as well. Note that
only the output voltage of the Slave is 'locked' when the Master LOCK is used; the current controls
of the Slave remain independent.
The LOCK key on the Slave output is ignored and pressing it causes the message
to be shown momentarily in the Slave display as a reminder.
