Instrument Transmitter Callibration


This is a simple tool that works out the callibration details for an analog transmitter. Transmitter outputs of 4 to 20 mA, 0 to 20 mA or 1 to 5 V are supported.

The tool provides a callibration table for loop check along with a chart. The typical 5 point check values (0%, 25%, 50%, 75% and 100%) are highlighted in the table for reference during transmitter loop checks. In addition, the tool has a calculator to help calculate the process values for a given transmitter output.

How to use

Choose the transmitter output type from the drop box and fill in the transmitter details in the cells provided.

Transmitter settings

The callibration table and chart are automatically updated. The red dotted lines on the chart indicate over/under range values.

To calculate the transmitter reading for a given output, use the scrollbar or use enter the value in the cell to the right of the scrollbar. The process value is calculated automatically.
