Description NJ300A 0Hz ~ 300kHz Portable LCR Tester 2.4-inch Color Screen High Precision Full Automatic Range LCR Meter Description: – The NJ series impedance tester adopts a high-performance processor and ultra-low power consumption design. It is a portable product mainly used to measure parameter performance of three basic components (resistance R, capacitance C, and inductance L). The product has a built-in large-capacity lithium-ion battery. It is small in size, light in weight, and easy to carry. It is more convenient to use for outdoor and high-altitude special operations. Display screen interface and buttons are clear and simple, at a glance, Chinese and English can be set by yourselves, easy to use and simple to operate. It is designed with online test function. Main Features: – Test frequency range is wide. Frequency range: 0 ~ 300KHz. The frequency point is continuously adjustable (except for NJ100S). The ultra-wide testing impedance range: 0.1mΩ ~ 20GΩ. – Small size, light weight, easy to carry. Appearance size: 130 x 108 x 31 (mm); net weight: 315g. – Built-in battery, using 2000mAH polymer lithium battery, continuous working time exceeds 8 hours. – High resolution, and measurement result is in 6-digit. – With calibration function, accurate measurement. – With online test function, cost-effective. – Serial/parallel mode, level and internal resistance are optional. – Strong anti-power frequency interference, and the interference level prompts. – Automatic gear shift, no manual pre-preparation is required. – Test level can be set arbitrarily. Specifications: – Product model: NJ300A – Working frequency: 0Hz ~ 300KHz – Stepping: 10Hz ~ 10KHz – Measuring resistance range: 0.1mΩ ~ 20GΩ – Display: 2.4″ TFT, resolution 320×240 (QVGA) – Battery capacity: 2000mAH (7.4Wh) – Power consumption: <1W - Charging current: 400mA - Charging port: USB (only as a charging port) - Automatic shutdown: always on, immediately off, 5 minutes ~ 60 minutes (optional) - Measurement parameters: Rs/Xs/Rp/Xp/Cs/Cp/Ls/Lp; |Z|/D/Q/θ/Vrms/Irms; Series equivalent resistance Esr=Rs - DC bias: None - Display resolution: 6 digits effective value - Measuring speed: fast, medium, slow - Volatility: 1kHz < 0.1‰(|Z|: 1Ω ~ 20MΩ), <0.5‰(|Z|: 500mΩ ~ 50MΩ) - Measurement accuracy: <0.1‰ (within impedance 1Ω ~ 20MΩ) - Connector: BNC - Display range: |Z|, R, X: 0.00001mΩ ~ 9999999MΩ C: 0.00001pF ~ 9999999F L: 0.00001nH ~ 9999999H D, Q: 0.001 ~ 99999 θ (Degrees): -179.9 ~ 179.9 Vrms: 0.0001mV ~ 999999mV Irms: 0.0001nA ~ 999999mA - Level (mVrms): arbitrarily set (1 ~ 1000, step 1; The maximum level limit at 30Ω internal resistance is 600) - Output impedance: 30Ω, 100Ω (optional) - Model: automatic, series, parallel (optional) - DUT: Automatic, resistance, inductance, capacitance, electrolysis (optional) - Calibration function: open circuit, short circuit (with factory value), load calibration - Appearance size: 130 x 108 x 31(mm) - Net weight: 315g - Working temperature: 5â~40â - Atmospheric pressure: 860hPa~1060hPa Functions Overview: - This product has three basic interfaces: measurement, calibration, and system interfaces. The "Measurement" and "Calibration" interfaces also have sub-interfaces. By default, it will enter the main measurement interface when it turns on. - It can easily measure the impedance of about 1mΩ. For example, a wire of 1cm generally has about 6mΩ. - The impedance of 300MΩ can be easily measured, and the actual measurement is 20GΩ. See the pictures below for details. The LCR bridges on the market basically cannot measure such a large impedance. - Currently, the fast mode is updated to refresh every 0.4 seconds. - It can measure the internal resistance of the battery. (It is necessary to connect a capacitor in series to cut off the DC voltage. The capacitor is connected in series with the battery. Since the capacity of the battery is large, the entire capacity after connection is approximately equal to the capacity of the Electrolytic capacitor.) Package Included: - 1 x Set of LCR Meter Precautions: - In order to ensure the accuracy of measurement and calibration, please warm up the product for at least 5 minutes before measuring. Especially when doing calibration, it is best to warm up for more than 20 minutes. After warming up, calibration parameters can be more accurate. - When powered by a battery, the internal noise of the product is the smallest, so it is recommended to measure under battery power. Especially when doing the calibration operation, it is strongly recommended to do it under battery power supply. When a charger is connected, if the quality of your charger is not good, a certain amount of noise will be generated. - Do not connect to a computers USB charging port for charging. The signal from the USB port will seriously interfere with the working state of the product and cause serious inaccuracy in product measurement. - In situations with high precision requirements, please try to use high-quality fixtures and set the power frequency to 50Hz and medium speed or above, as the instrument is calibrated in this state before shipment. - Before measurement and calibration, please make sure that there is no strong interference signal around, so as not to cause inaccurate measurement results due to interference. - When the battery is low, please charge it in time to avoid long-term lack of power. - The interface is BNC. Since copper has relatively lower strength than other metals, please try to protect it carefully to avoid falling and bumping damage. - In the case of strong interference, unconventional operation, and abnormal software unknown bugs, a crash may occur (the power may be consumed after the crash, until the battery is exhausted). At this time, please directly press the "RESET" hole to reset the product to avoid damage to the battery. If the battery is exhausted and the battery is extremely short of power, the current will be large during charging, and the charger with a small power supply current will have short-circuit protection, but please continue to charge until the battery can be charged normally. - When the power is lower than 15%, it will not be able to turn on; when the power is very low, the system will automatically shut down. Please charge in time. - When measuring large capacitances (uF level), the "electrolysis" item is more accurate than the "capacitance" item. - The device under test cannot be charged, especially the energy storage device (such as electrolytic capacitor), it must be discharged before testing, otherwise it may It will damage the instrument. - When measuring milliohm-level devices, if more accurate is required, please perform short-circuit calibration again under the same conditions as the frequency to be measured. - When calibrating, try to stay away from the surrounding environment interference, preferably away from the mains, such as wires and sockets. When measuring, use the battery of the instrument to work, do not plug in the USB port for power supply. Payment Terms 1. We accept PayPal,Payoneer,Visa Card,Google pay,Credit card etc. 2.
