### Step 4
Verify the **Voltage** reading with the multimeter and if needed change the voltage offset in V with command: <BR>&nbsp;&nbsp;&nbsp;&nbsp;`VoltageSet 235.5`<BR>&nbsp;&nbsp;&nbsp;&nbsp;*(235.5 would be replaced with your measurement which varies depending on the electrical standards and your electrical grid)*
### Step 5
Verify the **Current** reading by calculating current value (amperage) using formula **P<sub>(W)</sub>/I<sub>(V)</sub>=I<sub>(A)</sub>** and if needed change the current offset in *mA* (mA=A\*1000) with command:<BR>&nbsp;&nbsp;&nbsp;&nbsp;`CurrentSet 254.777`<BR>&nbsp;&nbsp;&nbsp;&nbsp;*(instead of 254.777 enter your calculation value of ***A multiplied by 1000***)*
Verify the **Current** reading by calculating current value (amperage) using formula **P<sub>(W)</sub>/U<sub>(V)</sub>=I<sub>(A)</sub>** and if needed change the current offset in *mA* (mA=A\*1000) with command:<BR>&nbsp;&nbsp;&nbsp;&nbsp;`CurrentSet 254.777`<BR>&nbsp;&nbsp;&nbsp;&nbsp;*(instead of 254.777 enter your calculation value of ***A multiplied by 1000***)*
### Step 6
Confirm the validity of your calibration process checking **Power Factor** from the WebUI which should be `1.00` or as close as possible to `1.00` (In theory resistive loads will always provide a **Power Factor** of 1.00). If that is not the case, we recommend to repeat the calibration process and make sure everything was done correctly.
