Description: It is used to measure the opening phase condition and order through LED and Buzzer. Measuring frequency range:20Hz~400Hz Operational Voltage:60V~600V (3 Phase AC) First, the product overview This instrument is based on the Safety Requirements for Electronic Measuring Instruments. Designed and manufactured by the secondary safety standard (LEC-348), it is easy to carry; the test is fast and accurate; and the safety is high. It is used to detect the order of the state and phase of the open phase, and the order of the phases is indicated by a light emitting diode (LED) and a buzzer. Second, matters needing attention 1. The instrument is a high-voltage test equipment. Before use, observe whether the instrument is in good condition. If it is the following, it must be stopped. It should be inspected and repaired to avoid electric shock and unsafe accident. A: The appearance of the meter is obviously damaged (such as cracks or damage to the casing, broken test leads, etc.); B: The meter is severely squeezed during transportation; C: The instrument is left unused for a long time under improper conditions (such as in a bathroom or a damp place). 2. Never open the outer casing of the instrument during the measurement process to avoid electric shock and unsafe accidents. 3. During the measurement process, a large voltage is input from the test lead. Do not touch the exposed wire end or the metal part of the test lead directly by hand to avoid electric shock. 4. Although sometimes all the phase indicators are not lit, there is still a voltage loop, so be careful to prevent electric shock. 5, the circuit voltage should not be higher than 600V when measuring, so as to avoid unsafe accidents. 6. When measuring 200V ACV, the continuous use time should be no more than 60 minutes; when measuring 600V ACV, the continuous use time should be no more than 4 minutes. 7. In the outdoor and damp environment when it is raining, the instrument cannot be used for measurement to avoid unsafe accidents. 8. Do not expose the meter to water or other corrosive liquids, or to expose it to direct sunlight or high temperatures and humidity, so as not to affect its test performance. 9. Non-professionals are prohibited from opening the outer casing of the instrument to avoid affecting its test performance. 10. Operators using the instrument should be specially trained to understand the knowledge of high-voltage operation and measurement, and perform measurement operations in strict accordance with the instructions. Third, technical characteristics Working voltage: 60~600V (three-phase alternating current) Maximum withstand voltage: 2000V / min (pulse voltage 4000V) Measured frequency range: 20Hz~400Hz Continuous use time: 200V ACV, no more than 60 minutes, 600V ACV, no more than 4 minutes Meter size: 85X64X23mm (excluding test leads) Weight: about 200g Instrument accessories: Test leads and test leads, test clips, straps, instruction manuals and carrying cloth bags. Fourth, the appearance of the description 1. Open phase check LED: Three orange LEDs indicate U phase, V phase and W phase. 2. LEDs for phase sequence check: one red LED and one green LED 3, the strap: set on the wrist to avoid the instrument slipping from the hand. 4. Test the test pen. 5. Test wire: red corresponds to U(R) phase (L1, R). Yellow corresponds to the V(Y) phase (L2, S). Green corresponds to the W(B) phase (L3, T). |
