Multi functional dual clamp nuclear wire tester

Main indicators

• Adopting a 2.4-inch LED screen LCD display with high brightness backlight.
• One screen displays 16 sets of data, the interface is intuitive and clear, and the measurement data can be locked.
• Measure the true effective value of voltage and current, display various phase relationships of U-U, U-I, I-I, and measure real-time on-site data such as active power, reactive power, apparent power, frequency, power factor, impedance, reactance, etc.
• The dual channel symmetrical design ensures mutual insulation, safety and reliability. It can detect and distinguish the wiring group of transformers. When measuring the U-U phase value, the two voltage input circuits are insulated and isolated, which will not cause a short circuit in the tested line or burn out the instrument.
• The instrument can directly measure the effective value of power frequency voltage, with insulation isolation between input circuits; Measurement range 3V-550V, fully automatic range switching, no need for users to switch ranges based on the measurement voltage range.
• 5mA-10A or 1mA-5A accurately measure phase, fully automatic range, without the need for users to switch ranges based on current amplitude.
• Automatic limiting, automatic recognition and measurement of voltage effective value or current effective value or phase angle measurement.
• When measuring over limit (voltage 500V, current 10A), the host should emit an alarm sound, and the over limit voltage or current should indicate "*****" to avoid user damage to the instrument or current testing clamp.
• Voltage core line function: LCD displays "U1:220.0V, U2:220.0V, Φ U1U2:120 °", buzzer emits interval sound, LCD prompts [*****], indicating that the signal measurement position is not on the same wire; The LCD displays "U1:220.0V, U2:220.0V, Φ U1U2:0 °", the buzzer emits continuous sound, and the LCD prompts [---], indicating that the measurement position of the signal to be tested is on the same wire; The LCD displays "U1:220.0V, U2:220.0V, Φ U1U2:180 °", the buzzer emits continuous sound, and the LCD prompts "[******]", indicating that the measurement position of the signal to be tested is on the same wire, but the phase is incorrect.
• Current core function: LCD displays "I1: 5.001A, I2: 5.002A, Φ I1I2: 120 °", buzzer emits interval sound, LCD prompts [* * *], indicating that the signal measurement position is not on the same wire; The LCD displays "I1: 5.001A, I2: 5.002A, Φ I1I2: 0 °", the buzzer emits continuous sound, and the LCD prompts [---], indicating that the measurement position of the signal to be tested is on the same wire; The LCD displays "I1: 5.001A, I2: 5.002A, Φ I1I2: 180 °", the buzzer emits continuous sound, and the LCD prompts [* * *], indicating that the measurement position of the signal to be tested is on the same wire, but the phase is incorrect.
• Equipped with automatic discrimination and prompt function for positive and negative phase sequence of three-phase three wire and three-phase four wire lines;
• Measure the load impedance (Z) to facilitate the inspection of the secondary loads of PT and CT, and effectively determine whether electricity theft is caused by a short circuit in the CT secondary circuit.
• All measurements do not require conversion wiring or gear shifting, and can automatically identify and measure the effective value or phase angle of voltage or current based on the user's current input.
• It has both positive and negative display functions. When the device is connected from the rear and held upside down, the display screen should be able to display in the positive direction for easy reading.
• Automatic power-saving management function, with automatic shutdown function when there is no operation.
• The instrument is powered by a built-in rechargeable lithium battery, and can work continuously for more than 18 hours when the backlight is turned off. When the backlight is turned on, it can work continuously for more than 6 hours and has a low power indicator.
• Equipped with a pointed nose clamp current transformer, it has high measurement accuracy and strong anti-interference ability, suitable for situations with dense wiring.
• Suitable for use as a wiring discrimination training tool and teaching instrument in various electric power colleges.
• Ultra small streamlined structure, anti drop wristband design, handheld, small size, light weight.
