Hi,
My customer is evaluating LDC1612EVM and calculate inductance value from frequency count from log data, but then the data is varied per power-on.
[Question]
- Should output data be exactly the same every time if all environment (temperature, voltage, distance to target… so on) is the same ideal?
[Condition]
- DUT : LDC1612, all external components are default
- GUI : LDC13xx16xx EVM GUI
- Target : SUS304
- Inductance value was calculated from Frequency Count value from log data
- Test procedure
- Power on and start 1st measurement for 30 min
- Power off and wait 30 min
- Power on again and start 2nd measurement for 30 min
- Continue this cycle four times
Please also see attached data.
