## User Guide

This temperature transmitter 4 to 20 milliamp current output calculator provides a way to determine the output reading from the applied temperature and temperature transmitter range. A conversion scale graphic for each temperature and 4-20mA current output range combination entered is also displayed below the calculated values.

### Formula

This temperature transmitter output calculator uses the following formula to calculate the output over a 4-20mA range:

Linear mA out = 4 + (16 x ((Rdg – Low Limit) / (High Limit – Low Limit)))

### Parameters

#### Unit

Enter the unit used for measuring temperature, e.g. °C, °F, degC, degF, etc…

#### Reading

This is the applied temperature measured by the temperature transmitter that you wish to convert to a 4 to 20 milliamp current output reading.

#### Low Limit

Enter the lowest temperature that the temperature transmitter will measure. You can enter negative (-) or positive (+) values. Please enter the value in the same temperature units as specified for all other input values.

#### High Limit

Enter the maximum temperature that the temperature transmitter will measure.

#### Output Reading (mA)

This is the expected ideal temperature transmitter current output signal in milliamps for the applied temperature specified.
