These values are calculated based on the formulas kW33W = PF33W = kVA33W = kWRS(L1L2) + kWTS (L3L2) kW 33W kVA 33W kW233W - kVAR233W · To obtain a more accurate kVAR value when the power factor (PF) is greater than 0. 91, use the 33W function. · The kVA value is shown on the main display and the kVAR value is shown on the upper display. · Positive kVAR (+) indicates a capacitive load, while negative kVAR (-) indicates an inductive load. Note: The "+" sign on the jaw must face the power source for correct measurement. To measure AC+DC Apparent and Reactive Power (kVA/kVAR) in a single phase 3-wire system See section on 13W AC+DC Power Measurements kVAR33W = kVARS(L1L2) + kVARTS(L1L2) To Measure AC+DC Power Measurements in a three phase 3-wire system · Set rotary switch to 33W without jaws clamping onto any wire. · The LCD display will show a flashing R to indicate that the meter is ready for the first measurement. · If the watt reading is not zero, press the DC A/W ZERO button once to zero out the watt reading. · Insert the black test lead into the COM terminal and the red test lead into the + terminal. · Pressing the READ NEXT button clears the stored data from memory and readies the power clamp for another three phase 3-wire calculation. Note: The "+" sign on the jaw must face the power source for correct measurement. Note: In the 33W unbalanced power measurement, one of WRS or WTS could be negative. Make sure all the connections and clamping are correct to obtain correct power and power factor measurements. 13W AC+DC Power Measurements The measurements for a single phase 3-wire system are similar to a three phase 3-wire unbalanced measurements, except the nomenclature is different. To Measure AC+DC Power Measurements in a single phase 3-wire system · Set rotary switch to 33W without jaws clamping onto any wire. · The LCD display will show a flashing R to indicate that the meter is ready for the first measurement.

Based on the kVAR values of the system, capacitors are available to improve the power factor. By measuring the frequency, phase voltage and kVAR of the system, you can calculate the capacitive load required for this correction. [. . . ]
