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. 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 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. Digital output is available at the USB port and 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 program are available for the Model 3000 Capacitance Meter. The Model 3000 LabVIEW© demonstration program is a standalone executable file that requires only the LabVIEW© runtime engine to load and run. When 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 disk file. A screen shot of the LabVIEW© demonstration program can be found here. 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 CD shipped with each instrument, or they can be downloaded here. We currently support LabVIEW© versions 7.1, 8.2, and 8.5. A factory installable upgrade with all of the digital I/O features is available for most older instruments. Contact sales@glkinst.com for details. 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. *United States Patent No. 4806846, LabVIEW© is a registered trademark of National Instruments www.ni.com Return to top of pageManual and Price List Operating Manual and Complete Specifications Operating Manual and Complete Specifications (Adobe PDF format) Current 2010 Price List (Adobe PDF format) Click here to get latest Adobe PDF reader Return to top of pageOrdering We accept checks drawn on a US bank, wire transfer (bank fees apply, usually $25), money orders, company purchase orders, and PayPal.
