If the outlet's physical state doesn't match the expected state, (e.g. it will be switched on in sequence ), its state is
marked by:
• a minus/plus sign
for outlets that are physically off, but should be on, or
• a plus/minus sign
for outlets that are physically on, but should be off (this should be rare).
The
button switches the selected outlet on, likewise the
button switches it off.
You can press and hold each of the buttons for 3 or more seconds to lock the outlet in the corresponding state.
Locked outlets can't be manipulated from web UI or with scripting, and won't be switched by using the hardware
/
keys unless you hold the corresponding key for 3 or more seconds to unlock it. Locked outlets are displayed
as:
• a zero sign
for outlets that are locked off, or
• an asterisk
for outlets that are locked on.
The
button cycles the selected outlet unless it's locked.
Managing outlet lock state can only be done using the LCD and keypad (unless you enable SSH). Locked outlets'
states cannot be altered, and they are not affected by
. However, they are still affected by
over-current, over-voltage, and low-voltage safety shutdown configuration.

Meter mode
Meter mode
In Meter mode, the
and
keys allow to choose the selected meter. The name of the selected meter is
displayed together with its current measured value.
Meters can be calibrated. Pressing the
button starts the calibration process for the meter. The leading character
of the line, previously a whitespace
, becomes an asterisk
to indicate that.
Meter calibration submode
The calibration progress and method are shown on the bottom line. For example, for voltages and currents, single-
point scale calibration is used, so "1/1 SC" (first and only point, scale) is displayed.
