Description -The Model 3000 Capacitance Meter is still the first commercially available low cost, high accuracy instrument designed exclusively for the measurement of very small value capacitors and capacitors whose size and shape are not conveniently handled by conventional sockets, clamp fixtures, or alligator clip leads. The Model 3000 is particularly useful for measurement of chip capacitors whose small size precludes the use of identifying marks. Other uses include measurement of the capacitance between the traces on a printed circuit board, thin film capacitors, MOSFET gate capacitance, microstrip or stripline capacitance, etc. The analog output and wideband options provide a convenient and low cost solution for characterization of the dynamic capacitance of MEMs devices. Complete specifications can be found in the Operating Manual.The Model 3000 uses a patented* switched capacitor circuit and ratiometric measurement techniques to eliminate errors due to stray capacitance-to-ground and component drift. This unique circuit allows the test capacitor or structure to be remotely connected to the meter by two, miniature, shielded probes or by coaxial cables without affecting the zero, accuracy, or resolution of the instrument. NOTE - Most LCR and capacitance meters measure impedance and calculate capacitance from the reactive component of the impedance. While useful for many circuit application, particularly RF circuits, this is not may represent the capacitance calculated from the geometrical and fringing fields of the actual physical capacitor. Our Model 3000 Capacitance Meter accurately measures capacitance using the fundamental physical relationship between charge and voltage, Q=CV. ANALOG OUTPUT - Although the resolution of the Model 3000 LCD display is limited to 3 1/2 digits, higher resolution can be obtained using the low noise, 0 to 200 mV analog output signal on the back panel. When the analog output signal is connected to an external high resolution DVM such as an HP 34401A, Keysight 3458A, or Solartron 7061, the ultimate resolution and reading-to-reading noise of the Model 3000 is less than 10 ppm as shown in this plot of a 200pF air capacitor. DIGITAL OUTPUT - The USB port provides the user with additional range, resolution, and the ability to log data to a file. The USB port is fully supported by LabVIEW©. USB drivers and a LabVIEW© demonstration programs are available for the Model 3000 Capacitance Meter. SOFTWARE - The Model 3000 LabVIEW© demonstration program is a standalone executable file that requires only the LabVIEW© runtime engine to load and run. When the LabVIEW© demonstration program is launched, a virtual Model 3000 front panel is displayed along with additional functions that include plots of the meter readings and histogram, offset adjustments, sample rate, and data logging to a disk file. This is a screen shot of the LabVIEW© demonstration program, a screen shot showing baseline noise limit (~27aF) with zero input on the 2pF range, and a screen shot showing the stability over 26 hours. For many users, the demonstration program maybe all that is needed to acquire and store data. For users who wish to customize the demonstration program or write their own virtual instrument program, we provide a complete set of LabVIEW© VI's. The Model 3000 LabVIEW© demonstration program, USB drivers, LabVIEW© VI's, and software installation instructions are provided on the application DVD shipped with each instrument, or they can be downloaded here. We currently support select LabVIEW© versions 8.2, 8.5, 2009 through 2023. Contact us if you need support for a LabVIEW© version not listed in the download section. MULTIPORT OPERATION - LabVIEW© software version 1.21 allows up to 8 Model 3000 Capacitance Meters to be connected to one computer using a multiport-powered USB hub or over a network using a multiport-powered USB-over-IP hub. This is a screen shot of LabVIEW© version 1.21 showing meter selection button. Contact us for recommended multiport-powered USB or USB-over-IP hubs. CALIBRATION - The basic accuracy of the Model 3000 is +/- (0.1% of reading +2 digits). Each unit is calibrated using capacitor standards maintained by GLK Instruments. These standards are compared to our primary GR 1404-A Reference Standard Capacitor. Traceability to NIST is provided at no extra charge. Recommended calibration cycle is 24 to 36 months. *United States Patent No. 4806846, LabVIEW© is a registered trademark of National Instruments www.ni.com Return to top of page Accessories - Calibration Standards, DC Bias Adapter, LCR Meter Test Fixtures, & Short-Open Standards
CALIBRATION STANDARDS - We offer a line of low cost, 2-BNC (3-terminal) capacitor standards for a quick calibration check of the Model 3000 Capacitance Meter. Available values are: 10pF, 100pF, 1nF, 10nF, and 100nF. All capacitor standards are serialized with barcode for inventory tracking. BIAS ADAPTER - P/N 2901500-000 is available for use with the Model 3000 Capacitance Meter for device characterization under DC voltage bias. LCR METER TEST FIXTURE ADAPTER - Capacitor standards can be checked and calibrated using our custom, 4-BNC (5-terminal) to 2-BNC (3-terminal) LCR Meter Test Fixture Adapter (P/N 2901600-100) on any calibrated LCR meter with 22mm BNC terminal spacing. All LCR Meter Test Fixture Adapters are serialized with barcode for inventory tracking. We also have a low cost, 4-BNC to 3-terminal banana jack test fixture adapter (P/N 2901600-200) to check the calibration of IET/GenRad 1409-series Standard Capacitors or to check values of leaded capacitors, inductors, and resistors using your existing LCR meter. Recommended LCR meters include: Keysight or Agilent E4980A, E4980AL, E4981A Capacitance Meter, IET GenRad 1693 Precision LCR Meter, or Rohde & Schwarz LCX100 LCR Meter. SHORT-OPEN STANDARDS - These calibration standards are available for use with the LCR Meter Test Fixture Adapter for LCR meter short and open corrections. Additional details on the capacitor standards, short-open standards, LCR meter test fixture adapters, and bias adapter are here.
