Notes for AC current:
1. Frequency response: 45 to 500 Hz (sine wave).
2. Position error: 1% of reading.
3. AC conversion type for U1191A and U1192A: Average sensing, RMS indication.
4. AC conversion type for U1193A and U1194A: RMS sensing, RMS indication.
5. Maximum overload: 400 A RMS.
6. For non-sinusoidal waveform, add additional accuracy of (2% reading + 2% full scale) typically for crest factor ≥ 3.0.

Notes for capacitance specifications:
1. Capacitance measurement is not available with U1191A model.
2. Overload protection: 600 Vrms for short circuits with < 0.1 mA current.
3. The accuracy for all ranges is specified based on a film capacitor or better, and use Relative mode.
