After a FW update from V1.1 to 1.2 a sensor error occured within my RMS Monitoring.
Directly before the FW update there wasn't any error and the measurement value were displayed. The displayed temperature was app. 500°C.
After the FW update, the RMS displayed a "--.--"
Can anybody give me an idea about the reason?

If the resistance of the external sensor approximates close to zero Ohm (depend on the sensor and the applied temperature - normally high temperatures), the device can misinterpret this as a short circuit. This is a new function of the RMS-MLOG V1.2.
Solutions could be the use of another NTC sensor type with a higher resistance for the applied temperature range.
