The DIGISTANT® model 4463 is a high-precision calibration source with impressive versatility and accuracy. Every device is supplied with a DAkkS certificate. Compared to other calibrators, it offers a better error limit of 0.002 % across the entire voltage range.
To achieve consistently high quality levels and conform to standards and regulations, measuring instruments of all kinds require regular calibration. The DIGISTANT® model 4463 provides many of the functions needed for this purpose. Inaccuracies caused by the measuring leads can be compensated via sense lines using 4-wire technology.
All relevant information about the parameter settings and the accuracy being achieved is clearly laid out on the high-resolution color display. The dynamic menu system is navigated intuitively. Range selection is automatic or manual. Values can be entered precisely using the numeric or cursor keypad.
The device can be controlled via its Ethernet, USB or RS-232 port. LabView drivers for software integration are available free of charge. SCPI commands are listed in the user manual. 32 ramp functions per range with 100 value/time sequences can be automatically saved and started.
For thermocouples, scales including ITS-90 and IPTS-68, reference junction type constant or external, can be selected. An optionally available external Pt100 reference junction with calibration data taken into account in the device minimizes thermal EMFs and results in even smaller uncertainties in the measurement chain.
