1. Use the Up and Down buttons to select an outlet. Pressing the Up button once moves up one
outlet number. Pressing the Down button once moves down one outlet number.
2. When an outlet is selected, the outlet number is displayed in the lower row and the current in
the upper row. Current is displayed in the format: XX.X (A)
3. To display the voltage for the selected outlet, press the Up and Down buttons simultaneously.
The voltage reading will replace the current for about 5 seconds, after which the current will
return.
4. To display the power…
Tip: A quick way to distinguish between voltage, current, and power is the placement of the
decimal point in the display. Voltage has no decimal point, current has a decimal point between
the first and second digits, and power has a decimal point between the second and third digits.

The Revelation PDU includes branch circuit breakers (units rated over 20A) that automatically
trip when a power overload is detected. If the circuit breaker switches off the voltage rail, the
