One Calibration Source, Six Measured Variables

Measuring instruments and transducers have to be precisely calibrated for the respective measuring ranges before use, and in commercial applications they also require periodic recalibration. Often this calls for several high-precision calibration sources for different measured variables, and specially trained personnel. All this is expensive, demands training time, and takes up space in the laboratory or on the production line.

The Digistant 4463 high-precision calibration source from Burster in Germany provides a solution by combining six common measured variables in one device. A voltage range of +/-100 nV up to +/-100 V with a basic accuracy (B) of 0.002 % can be specified, or for example a current of +/‑100 nA … +/-50 mA, 0.005 % B, or frequencies from 10 mHz to 100 kHz and a true ohmic resistance simulation of 10 Ω to 300 kΩ. Thermocouples (12 types from 0.1 K B) or RTDs (resistance temperature detectors such as Pt100 … Pt1000, Ni100 … Ni1000) can also be calibrated.

Four-wire technology reduces uncertainties to a minimum. An optional Pt100 external reference junction optimizes the temperature simulation. Up to 32 fully automatic test routines, each with up to 100 value/time sequences, allow rapid testing of sensor cards, measuring instruments, PC expansion cards etc. at the touch of a button. In the laboratory or on the production line, measuring equipment can be conveniently tested in multiple measuring ranges using just one compact calibration source.

Flexible use made easy

An RS-232, USB and Ethernet port are provided for connecting to existing control systems and databases. Proprietary evaluation software was deliberately avoided. Instead, DIGISTANT 4463 offers a free driver for LabView. This allows users to work with their familiar and powerful standard software, making integration easier and drastically reducing training time. The calibration source is supplied with a DAkkS certificate, and can be used anywhere in the world with a supply voltage of 230/115 V AC (50/60 Hz). When the calibration period expires, the calibration source can be recalibrated in the manufacturer’s DAkkS-certified calibration laboratory.
