RDE300 series units shipped after PCB serial number 7300 (approximately March 2021) are configured with 1000 ohm Pt RTD temperature sensors (Pt1000). Earlier RDE300 series units may have 100 ohm Pt RTD temperature sensors (Pt100).
If replacing your RTD temperature sensor (see Replacing RTDs on RDE300 series units), you may also need to change your RDE300 series configuration settings to match the new sensor. To do this, import the appropriate settings file from the attachments to this article. For instructions on importing a settings file, see RDE300 Series User Guide.
