English translation of German description:
The Hewlett Packard 4272 A is a 1MHz/100kHz Preset C Meter
which measures capacitance at 1 MHz and at 1 kHz
, respectively, and which, combined with a 5 digit "in-house" comparator, provide GO/NO GO information for high speed measurements up to 8 per second with high reliability and accuracy.
A basic accuracy of 0.1% is achieved by the four-terminal-pair method and an offset adjustment to reduce measurement error due to test fixture configuration. This provides high efficiency for production line testing or incoming inspection.
The 4272 A measures capacitance from 10 pF full scale
(0.001 pF resolution) to 1000 pF
full scale (maximum display 1900 pF).
With its comparator capabilities, the instrument can be set to high and low limits with the built-in thumbwheel switches. Limit indications, include panel lamp display, relay contact, and TTL outputs for HI, IN, and LO comparisons. TTL outputs are provided on the rear panel connector for use with an automatic sorter and BCD output of measurement data is also provided.
