5. F THE DANGERS INHERENT IN MEASUR ING THREE PHASE CIRCUITS WE STRONGLY RECOMMEND THAT YOU DO NOT USE THIS MULTIME TER FOR SUCH APPLICATIONS We designed this multimeter primarily to measure household AC voltages If you want to measure 3 phase line to line voltages please note that the ac tual voltage can be greater than the circuit s rated line to ground voltage Most 3 phase power circuits are rated by their ine to line voltage This volt age is higher than the line or phase to ground voltage To determine if a line to line 3 phase voltage exceeds the rating of this multimeter multiply the rated line to ground voltage by 1 732 the square root of 3 For ex ample if the rated line to ground volt age is 300 volts the line to line voltage is 300 x 1 732 519 6 V AC Warning This voltage exceeds the multimeter s rating Therefore you should not connect the multimeter to this circuit or to any equipment con nected to the circuit Doing so could present a dangerous shock hazard to you and could also damage the mul timeter If you do not know why there is a volt age difference you should not be working on three phase power cir cuits These circuits are generally ex tremely powerful and very dangerous Special safety equipment should be worn when working around these dangerous circuits 12 Using the Multimeter Measuring AC Voltage Riding on a DC Source Bias To measure AC voltage superim posed
