VOLTCRAFT LCR-400 Bedienungsanleitung Seite 43

when measuring by basic accuracy that following conditions must be met:
• Ambient temperature: 23°C ± 5°C < 80%RH.
• Open and short calibration have been performed.
• D ≤ 0.1 for C, L measurements; Q ≤ 0.1 for R measurements.
• Do not measure when charge by AC adaptor. It may cause the reading rolling.
• See the operation manual for additional conditions.
Measurement tolerances
Statement of accuracy in ± (% of reading + display error in counts (= number of smallest points)).
The accuracy is valid for one year at a temperature of +23 °C (± 5 °C), and at a relative
humidity of less than 80%, non-condensing. Only valid if calibrated previously with open and
closed measurement input.
Dissipation factor „D" ≤ 0.1 for C and L-measurements; Quality factor „Q" ≤ 0.1 for R-
measurements.
Do not perform a measurement with the power adapter plugged in. This may cause the
displayed measurement values to fluctuate.
