Decade recalibration

Simple procedure of recalibration is accesible using decade CALIBRATION mode: - correct password must be entered befor calibration

Decade display password mode.

Decade display calibration mode.

- recalibration procedure consist of measuring basic resistance values and entering their actually measured data

- in following table nominal values of calibration points and requested recalibration accuracy are described

Remote control & Automatic calibration

Precision decades full automatic operatio using remote control mode. Following intrefaces are available for connection the calibrator to PC:

- GPIB ( IEEE-488 ) interface. Connector is located on the rear panel Nationa instruments GPIB card is requested to be installed in the computer.

- RS-232 serial line. connector is located on the rear panel.

- USB interface using RS-232-USB converter

- by user created application SW, using control commands SCPI

- using Meatest CALIBER application SW

Decades can be applied in systems for automatic and semiautomatic calibration ofUUTs:

CALIBER application software for automatic and semiautomatic calibration of meters of electric quantities.

CALIBER ProcedureCalibrationcertificate

Standard unit

Unit under test

CALIBER application software is based on instrument cards. Basic instrument card are delivered with decades,however new card be created by calibration laboratory.

- output from the CALIBER is list of calibration points with measured and evaluated results including uncertainty of calibration

- calibration procedures can be easily created by calibration laboratory
