Informazioni

The Datron 4700 Autocai Multifunction. Calibrator is a high-precision Calibrator which features exceptionally high stability and full systems capability. It is characterized by a wide-range coverage of DC Voltage, AC Voltage. DC Current, AC Current and Resistance functions in a single unit, VThe basic Instrument includes both DC Voltage and AQ.Voltage calibration sources up to the 100У range (200V maximum output). " Option 10 (factory-fitted) extends both DC Voltage and AC Voltage functions up to the 1000V range (1100V maximum output). Option 20 (field or factory-fitted) adds calibration sources of DC Current, AC Current and Resistance, The 4700 incorporates a reference module containing precision temperature-compensation elements, maintaining a high accuracy specification over the ambient temperature range of 23 °C ± 10°C A. high level of stability is achieved by use of super-selected reference components and ultra-stable gain-defining resistors. The ‘Autocar feature ensures that its 24-hour specifications are usable; not merely figures of merit. The 4700 uses a microprocessor for control management, simplifying its use in complex manual operations, such as calibration of high-quality digital multimeters. The IEEE 488 Interface provides a comprehensive remote programming capability, allowing programmed calibration of the 4700 itself

Here is an alternative (explanatory !) version of the Section Titles: Sect 1. Introduction and a brief account of the internal design. Sect 2. Physical connections and mounting — getting it installed. Sect 3. A brief scan of the available controls — where they are and what they do. Sect 4. The correct procedures for making the 4700 perform for you. Sect 5. How your 4700 can operate within an IEEE 488 system — the device dependent codes you will need to use. Sect 6. Specifications — what accuracy you can expect to get from your instrument. Sect 7. Verification that your 4700 matches the high specification it had when it left the factory. Sect 8. How to restore your 4700 to its original specification after it has suffered the ravages of time and temperature.
