PowerMoniSpot: Levels of calibration


Level 1 - Load profile (uncalibrated)

This is the default level of PowerMoniSpot.

This level measure and display the load profile, it displays the uncalibrated data and will not display current (ampere) or power (watt).

Note that the load must be single-phase (one live and one neutral conductor) or balanced across the phases if it is a multiple-phase system.

Level 2A - Manual calibration (ampere, watt)

This level works on any number of phases as long the loads are balanced across all phases, converting uncalibrated data into current (ampere) or power (watt).

To calibrate the PowerMoniSpot manually it is necessary to use a clamp-on ammeter to measure the ampere or knowing the exact specifications of the unit in either watt or ampere.

Level 2B - Single-phase auto-calibration (ampere)

This level auto-calibrate the uncalibrated data into current (ampere) with a ±25% precision tolerance.

You can only use this calibration level if the sensor is installed on a single-phase (one live and one neutral conductor) cable, no thicker than 8 mm.

Level 3 - Calibration with a PowerMoniMain (ampere)

This level offers precision calibration with assistance from a temporarily installed PowerMoniMain sensor. It works on all cable types with any number of phases, regardless of how the load is distributed across the phases.

Sensors calibrated with this method will generate precise current data for each individual phase. When calibrated with a PowerMoniMain the precision tolerance is ~1%.

Level 4A - Full sub-meter, using PowerMoniMain (ampere, volt, power angle)

This level offers precision calibration with a permanently installed PowerMoniMain in the switchboard measuring the voltage in combination with the Level 3 calibration. It works on all cable types with any number of phases, regardless of how the load is distributed across the phases.

Sensors calibrated with this method will generate precise data for each individual phase. When calibrated with a PowerMoniMain the precision tolerance is ~1%.

At level 4, you have a full sub-meter solution, naturally with the high resolution and IoT integration of the PowerMoni solution.
