Denition of all selectable output signals as soon as pressure transmitter is selected for

the calibration. Depending on whether it is a voltage or a current signal, the multimeter

will be congured and, if required, a shunt will be needed.

Denition:

“Lower range limit” = Start of measuring range

“Upper range limit” = End of measuring range

The COM port for the calibration items will be discovered automatically. Under

“Baudrate duc”, the baud rate is set with which the measurements will be made.

If a mass ↔ pressure calculation is carried out for pressure balances with WIKA-CAL,

the values will be corrected. The specication of the height dierence to the test item

corrects the calculated pressure value around the entered height dierence. The

accuracy of the measured height dierence is entered into the measuring uncertainty

calculation.

The residual pressure is also required for the correction with pressure balances, though

only for absolute instruments. The accuracy with which this is measured is added to the

measurement uncertainty.
