Model 240C - Precision Kelvin Ratio Bridge

DESCRIPTION: The Model 240C Kelvin Ratio Bridge, used in the 242D system, allows comparison of resistors to .5 PPM either by interchanging resistors or reading their values directly. Direct readout is possible to an accuracy of .001% using the Model RS925D Decade Resistance Standard. The 240C may also be used to determine deviation of a resistor from a known standard.
FEATURES: Up to .1 lead compensation, .01 - 100 multiplier ratios, 1 year warranty

APPLICATIONS: Calibration laboratories where the nominal values of transfer or working resistance standards must be measured or compared to the values of primary resistance standards.

Model 801B - DC Generator Detector w/ Power Limit

DESCRIPTION: The Model 801B is an integral part of the 242D system. Its primary function is to generate a calibrated, power limited DC excitation signal that is applied to the DUT and/or reference standard and to use the detector as a voltmeter for measuring applicable low or high level voltages critical for making accurate measurements.
FEATURES: Generator has six, continuously variable ranges from 0V to 600VDC. Power Limited to 1W. The detector has 8 galvanometer, (zero centered) ranges from 1µV to ±1000VDC, 1 year warranty

APPLICATIONS: Calibration laboratories where the nominal values of transfer or working resistance standards must be measured or compared to the values of primary resistance standards. Other applications where a precise, power limited DC source and meter is required.

Model 801C - DC Generator Detector w/ Power Limit & Short Circuit Sense

DESCRIPTION: Model 801C has the same functionality as the Model 801B except that it has a built in short circuit sensing and protection circuit.
FEATURES: Generator has six, continuously variable ranges from 0V to 600VDC. Power Limited to 1W. The detector has 8 galvanometer, (zero centered) ranges from 1µV to ±1000VDC, 1 year warranty

APPLICATIONS: Calibration laboratories where the nominal values of transfer or working resistance standards must be measured or compared to the values of primary resistance standards. Other applications where a precise, power limited DC source and meter is required with the addition of a short circuit sense and protection circuit is required.
