WARNING! 1. DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE RATINGS: - Voltage is not to exceed 800 Volts. - Wattage, Resistance and Continuity functions are not to be performed on circuits capable of delivering greater than 600 Volts. - Current measurements are not to be performed on circuits capable of delivering greater than 500 Volts 2. To avoid electrical shock hazards and/or damage to the meter: - Do not exceed the voltage ratings for the meter. Use caution when measuring voltage.
φ KVAR KVA Button • The 3φ KVAR KVA button toggles between the KVAR/KVA measurements and the PF/kW measurements in the 3φ3W or 3φ4W functions. • Toggling between these measurements can only be done after the power clamp has calculated the power factor and kW measurement. Read Next Button In 3φ3W Function • Pressing the read next button stores the measured values for kWRS(L1L2)/kVARS(L1L2) and moves to the next measurement.
To measure Kilowatts and Power Factor in a single phase 2-wire system • Set rotary switch to PF/kW without jaws clamping onto any wire • 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. • Connect the black test probe to the neutral conductor and the red test probe to the hot conductor.
• The voltage value is shown on the main display and the frequency value is shown on the upper display. Note: If the frequency is <10Hz, the display will show 0Hz. If the frequency is >1000Hz, the display will show OL.

To Measure AC+DC Apparent and Reactive Power (kVA/kVAR) in a single phase 2-wire system • Set the rotary switch to A/V. • Press the DC A/W ZERO button to zero the reading. • Set the rotary switch to kVA/kVAR. • Insert the black test lead into the COM terminal and the red test lead into the + terminal. • Connect the black test probe to the neutral conductor and the red test probe to the hot conductor. • Using the trigger to open the jaws, fully enclose the hot conductor within the clamp.

• The power clamp processes the two sets of data and calculates the true power (kW) of the system, which is shown on the main display, and the power factor (PF), which is shown on the upper display. RST is shown on the LCD display to indicate that this is a measurement of the total system. • Pressing the 3φ KVAR KVA button toggles to display the apparent power (kVA) of the system, which is shown on the main display, and the reactive power (kVAR), which is shown on the upper display.
• Connect the black test probe to ground and the red test probe to the second phase (T or L2). • Using the trigger to open the jaws, fully enclose the phase (T or L2) within the clamp. • Release the trigger and be sure that the jaws have closed completely. • Wait until the reading is stable, and press the READ NEXT button to capture the reading, storing the data in memory. 3φ4W AC+DC Power Measurements Kilowatt Range (AC+DC True Power) 0-99.99kW 100-999.

Power Calculations Power Factor Corrections A positive power factor indicates that an inductive load has brought the power system out of phase. 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. Single phase capacitors can be used in a 1φ2W or 3φ4W systems. Three phase capacitors are available for 3φ3W and 3φ4W systems.
