Other Features | - When connecting any 3 phase equipment to the 3 phase power, the first step is to check the phase sequence of the 3 phase power supply. This instrument is a handy and essential instrument for checking the phase sequence in 3 phase Circuits. When connecting motors, energy meters, watt meters, Power factor meters, Power factor controllers, Power meters etc, it is very important to connect the equipments in proper phase sequence, otherwise the instrument / equipment can be damaged or give incorrect readings., It is used to measure the Phase sequence (R,Y,B) & Open phase Condition through LED and Buzzer., Operational Voltage : 60 ~ 600V (3 phase AC), Dielectric Strength : 2000V / minute (impulse Voltage 4000V), Measuring frequency range : 20Hz ~ 400Hz, Time limit for continuous measurement : 60 min. at 200V AC, 4 min. at 600V AC, Accessories - Test leads with Pin Terminal & separate Insulated Crocodile clips
