Fluke 5450A Calibrateur
Fabricant:
Fluke
Modèle: 5450A
Date: 1984
Catégorie: Mètres
Groupe: Calibrateur
Description: Resistance Calibrator
Information:
                                    The Fluke 5450A Resistance Calibrator is designed to
facilitate manual or automated calibration of the resistance
measuring circuitry of high-quality digital multimeters
(DMMs). The 5450A provides cardinal point resistances in the
range of 1Ω to 100 ΜΩ. Resistances may be selected either at
decade points (e.g., 1Ω, 10Ω, 100Ω, etc.) or at xl.9 points
(e.g., 1.9Ω, 19Ω, 190Ω, etc.).
The 5450A display indicates the value of the selected
resistance and can also indicate the error of the instrument
being calibrated (the unit under test, or UUT), expressed in
percent or parts-per-million (ppm).
The 5450A may be controlled from the front panel or by
remote control via the IEEE-488 interface bus. All functions
available on the front panel are also available over the
IEEE-488 bus.
The UUT may be connected directly to the 5450A front panel
terminals using banana plugs,
or to five-way low-thermal binding posts on the rear panel.
The 5450A is calibrated with its covers installed and may be
calibrated remotely via the IEEE-488 bus. Calibration
constants are stored in electrically alterable read-only
memory (EAROM).
Accessories available for the 5450A include a rack mounting
kit, rack mounting ears, and IEEE-488 interface bus cables.
