Features 1、Instrument base plate is provided with magnet, instrument can adsorbed on the metal shell when testing, the operation more convenient. 2、The dynamic sound and light indicates the positive or negative phase of the phase sequence of the three-phase power supply, which is clear at a glance. 3、More sensitive ETCR1000C clamp, can even sense the AC voltage signal as low as a few Volts, with a wider range of live electricity. 4、It has a better power-saving performance with the maximum rated power of 300mVA. 5、The three clamps of ETCR1000C are in three colors, it is more in line with the distinction of three-phase line, and more scientific and artistic overall appearance. 6、In addition to phase sequence detection, it also has the functions of live wire examination, simple power detection, fire-wire identification, phase deficiency determination, break location detection, DC line break and line maintenance, equivalent to 3 induction electric pens. 7、Field test, effectively protect the physical safety of operators and improve productivity. 8、Comes with a lanyard, compact size and lightweight, easy to carry. Specification Condition: 100% Brand New Item Type: Non-Contact Phase Sequence Detector Material: ABS Color: As shown in the picture Product Non-contact phase detector Functions Phase detection (normal phase, reverse phase and phase deficiency), live wire examination, simple power detection, breakpoint location and line maintenance Power Supply DC 3V 2 x AA batteries (LR6)(Not included), continuously working for 70 hours Voltage Range AC 70～1000V, 45～65Hz (Sine Wave Continuous Input) Clamp Wire Size Diameter: 10-40mm / 0.4-1.6in LED Display Positive Phase Sequence: The four phase-sequence lamps blink in order (clockwise). Negative Phase Sequence: The four phase-sequence lamps blink in order (counterclockwise). Line-voltage Indication: L1, L2, L3 lamp light up. Default Phase: L1/ L2/L3 lamp is off. Open Circuit: L1/L2/L3 lamp is off. Buzzer Positive Phase Sequence: The instrument emits intermittent short beeps Negative Phase Sequence: The instrument emits a continuous long beep Battery Check After the power is turned on, the POWER indicator is on: The battery is low. The LOW BATTERY light is on. Auto Power off After 5minutes, the meter automatically cut off power supply.
