RT-1 Out Of Range Calibration Setpoints
Sometimes the values entered for Temp1 and Temp2 and their corresponding input percentages will not
allow the RT-1 module to display the complete -150 to 400ºC temperature range. If this occurs the message
"Value is out of range!" will be displayed.
For example, after resetting the RT-1 module, Toolbox displayed 100ºC as 40% and 0ºC as 10%. This is
illustrated below. In order to cover the complete -150 to 400ºC range, the RT-1 module would need to use
the input range of -35 to 130% which it is unable to do as it is limited to 0-100% (0-32760).

Any input/temperature setpoints that will allow the RT-1 module to display -150 to 400ºC within 0-100% will
be in range and will allow the RT-1 module to be correctly calibrated. An example of acceptable setpoints are
100ºC=30% and 0ºC=20% and these are shown below.
