How to calibrate PowerMoniSpot: Level 2A - Balanced loads, manually (ampere or watt)


PowerMoniSpot can be calibrated to show consumption in both ampere (current) and watt (power) 

1. Clamp a PowerMoniSpot on a cable and make sure it is connected to the unit you wish to monitor. In this guide, we're using the unit "aircondition" as an example. Remember 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.

2. Go to recalc.remoni.com. 

3. Select "Units" in the menu and choose the unit you want to monitor on the list as seen below. Make sure that the sensor ID matches the PowerMoniSpot's ID. Click on the arrow next to "View" and select “Edit” in the drop-down menu.

4. In the top, select "Data."

5. Choose Level 2A below "New Calibration" in the drop-down menu.

6. Click on the calculator to enter the calibration constant - remember to choose between current (ampere) and power (watt) below "Calibrate for..." by clicking on the arrow.

7. To find the calibration constant, there are three options:

7.1 Power/Watt:

Step 1: Start by finding a "Base value" by mousing over the graph in ReCalc. Click on the value and it will appear in the calculator beneath "Base value" as shown below.

Step 2: Measure watt on the cable directly where the PowerMoniSpot is mounted, using a multimeter. Make sure to write down the value in the space "Target value in Watt" as shown in the box below. 

By typing the "Base Value" and "Target Value," the calculator will show a new calibration constant. 

When clicking the button "OK, use this calibration constant" the PowerMoniSpot is calibrated and you're all set.

7.2 Current/Ampere: 

Step 1: Start by finding a "Base value" by mousing over the graph in ReCalc. Click on the value and it will appear in the calculator beneath "Base value" as shown below.

Step 2: Measure ampere on the cable directly where the PowerMoniSpot is mounted, using an ammeter or multimeter. Make sure to write down the value in the space "Target value in ampere" as shown in the box below. 

By typing the "Base Value" and "Target Value," the calculator will show a new calibration constant. 

By clicking on the button "OK, use this calibration constant" the PowerMoniSpot is calibrated.

7.3 Read the value on the label

The majority of electric devices has a label which shows the consumption in either watt or ampere.

Watt: Find the manufacturer label on the device and look for the value in Watt. As described above, this value is the "Target value." Mouse over the "Base value" on the graph in ReCalc and type in the two values in the calculator as shown above.

Now, the new calibration constant for watt is found and you're all set.

Ampere: Many smaller appliances has a manufacturer label which shows the consumption in Amps. This is the "Target value". Mouse over the "Base value" on the graph in ReCalc and type in the two values in the calculator, as shown above. 

Now, the new calibration constant for ampere is found and you're all set.

Please note that the sensor needs to be calibrated again if you move it on the cable, or to a new unit
