881 In-Circuit ESR & DC Resistance Capacitor Tester

881 In-Circuit ESR (Equivalent Series Resistance) & DC Resistance Capacitor Tester is an essential tool for anyone working with printed circuit boards (PCBs). Designed specifically to measure ESR on capacitors within the range of 0.47uF to 2200uF, this tester allows users to troubleshoot capacitors both in-circuit and out of circuit. The ability to perform in-circuit testing saves significant time and effort, making the 881 an ideal choice for professionals who need to quickly identify faulty capacitors in electronic devices.

With a 100kHz output test frequency and a 15mVp-p output test voltage, the 881 ensures that solid-state devices are not inadvertently activated during testing. The device is microprocessor-controlled, ensuring accurate, reliable measurements, and it also features an automatic discharge function to safely discharge capacitors after testing. For added convenience, the 881 comes with a one-handed tweezer test probe, making it easy to operate in confined spaces or on densely populated PCBs.

The 891 Benchtop LCR meter is a highly versatile instrument capable of measuring inductance, capacitance, and resistance at DC or from 20 Hz to 300 kHz. Featuring a 4.3″ color display, the 891 allows for easy viewing of measurements and parameters on a single screen. This meter also includes a bin sorting function and a frequency sweep function for quick sorting and characterization of components.

The 894 and 895 are high-accuracy LCR meters capable of measuring inductance, capacitance, and resistance of components and materials. These meters offer flexible AC and DC test signal configuration with AC test signal voltage adjustable up to 2 Vrms and DC bias signals from -5V to +5V. The 894 operates up to 500 kHz, and the 895 up to 1 MHz. These LCR meters are designed for high-precision applications in R&D, manufacturing, and quality control.

878B, 879B, and 880 Handheld LCR Meters

The 878B, 879B, and 880 handheld LCR meters are precision instruments designed for measuring inductance, capacitance, and resistance with high accuracy and efficiency. The 879B and 880 models also measure impedance, Theta, DCR, and ESR. The 880 offers advanced features typically found in bench LCR meters, such as a 4-terminal configuration, accuracy up to 0.1%, test frequencies up to 100 kHz, and selectable test signal levels.

These LCR meters are ideal for a variety of applications with their fast auto-ranging, intuitive measurement configuration, and practical features like data hold, Min/Max/Average recording, tolerance sorting, and relative mode. Measurement data can be continuously transferred to a PC via the mini USB interface, and the provided software allows for data logging and remote control using SCPI commands.

2840 Series DC Resistance Meters

The 2840 Series DC resistance meters provide high-accuracy and high-resolution measurements in the milliohm range, making them ideal for applications such as measuring the contact resistance of relays, switches, and PCB traces—all typically outside the measurement range of standard multimeters. Equipped with a 4.3-inch TFT LCD color touch screen and keypad, these meters offer an intuitive user interface for easy operation.

The 815 Component Tester is a versatile, handheld instrument capable of testing a wide range of electronic components, including capacitance up to 20 mF and resistance up to 20 M ohms. Additionally, the 815 tester offers transistor, beta, diode, SCR, LED, and battery testing capabilities, making it a comprehensive tool for both professionals and hobbyists alike.

The 830C and 890C are handheld, 11,000-count capacitance meters designed to measure capacitance up to 200 mF (for the 830C) and 50 mF (for the 890C). With their straightforward operation and fast measurements, these meters simplify the capacitance sorting process, offering high accuracy and convenience for component testing and troubleshooting.

Unlike typical handheld LCR meters that use an AC signal for testing, the 830C and 890C utilize a constant current to charge and discharge capacitors, making the measurement process efficient. They include features like compare mode, which supports 25 sets of High/Low limits, allowing users to easily sort capacitors without needing to reset the meter for each test.
