TROUBLESHOOTING

Model 244EH software version 5.5.1

To determine the software version of a Model 244E temperature transmitter, first connect the transmitter to the Model 244EC configurator, open the 244EC software configuration tool, and then choose “Service “from the 244EC software menu.

The configuration of the Intermittent Sensor Detect feature of the Model 244E Temperature Transmitter with version 5.5.1 or greater software cannot be changed with the Model 244EC version 2.0.0 or earlier. If you attempt to change the configuration of this feature and then click the SEND TO XMTR button, the following screen will appear.
