The RMS-MLOG-T10-868/915 currently offers the possibility to match the NTC with a lookup table, when using the lookup table, the measurement accuracy is valid throughout the temperature range.
The lookup table is stored on the RMS-MLOG-T10-868/915's memory. This memory is programmed at Rotronic AG. It is not possible to update the lookup tables without returning the device to Rotronic AG. A device will only show the lookup tables that are stored on the device memory independent of the firmware version.
If the lookup table for an NTC is not available, then the user must either update the device (return it to Rotronic AG) or add the R25 and B constant based upon the table below:

Should the T10 probe be used with the RMS-MLOG-T10-868/915 outside of the temperature range, then the RMS-MLOG-T10-868/915 will show "NaN" in RMS-CONFIG and "---" in the RMS software.
Important: Please be aware that the RMS-MLOG-T10-868/915 units will only show results when working at the T10 NTC's operating temperature defined in the table above. |

Important: The lookup tables are stored on the EEPROM of the device and not within the firmware. If the EEPROM needs updating to include new lookup tables, the MLOG-T10 must be returned to Rotronic AG. |
