Calibration
8 PCS and PCS2 Power Current Sensors
If the unit has both STANDBY and ON states, follow these steps:
1. Turn the STANDBY and ON potentiometers (POTs) clockwise until they stop.
2. Plug the PCS into an outlet and plug the unit (the device you are monitoring) into the PCS.
This power provides the unit with power. There are three power conditions that most units
exhibit: ON, Standby, and OFF.
3. Plug an cable from the PCS to a Central Controller to provide power to the PCS unit.
4. Set the unit to the desired STANDBY power mode. This is obtained by plugging the device
into an electrical port and not turning the power switch/button ON.
5. Turn the STANDBY POT counterclockwise until the status LED turns off. Then, turn it slowly
clockwise until the LED turns on.
6. Set the unit (device being monitored) to the ON state.
7. If the STANDBY LED stays on, turn the ON POT counterclockwise until:
! The ON LED turns on.
! The STANDBY LED turns off.
8. Set the unit to the Standby mode.
9. If the ON LED stays on, turn the STANDBY POT counterclockwise until:
! The ON LED turns off.
! The STANDBY LED turns on.
10. Repeat steps 5 through 9 to calibrate the PCS.

If the unit only has an ON state, or if the PCS is sensing the ON state, perform step 1.
If you are using only the STANDBY mode, focus on steps 3 and 4.
