Fluke - 5440B Programmable Voltage Calibrator

Fluke - 5440B Programmable Voltage Calibrator
Price: £2,750.00
Manufacturer: FLUKE

The 5440B direct voltage calibrator is equipped with bright displays for clear visibility at any viewing angle. The 5440B is easy to use because the 40-character, alphanumeric display provided in addition to the numeric output display, makes operating instructions and error messages clear and readable in engineering units and English messages instead of coded numerics.

For semi-automated testing, the 5440B lets a complete test sequence of up to 60 steps be stored in the internal Procedure Storage memory and recorded for later use in the interchangeable plug-in Procedure Storage modules. A test sequence is recalled and executed one step at a time with each touch of the NEXT STEP key.

The excellent accuracy specifications for the 5440B are easily maintained in any lab by performing the simple automatic calibration procedures, which store the calibration constants in non-volatile memory. No hardware adjustments are required.
