Notes for AC current specifications:
1 Overload protection:
• U1191A and U1192A: 400 Arms
• U1193A and U1194A: 600 Arms
2 Input impedance for 60 µA to 600 µA range: 4.2 k
3 Frequency response: 45 Hz to 500 Hz (sinusoidal waveform)
4 Position error: 1% from reading
5 AC conversion type:
• U1191A and U1192A: Average sensing, RMS indication
• U1193A and U1194A: RMS sensing, RMS indication
6 For non-sinusoidal waveform, add an additional accuracy of (2% of reading + 2% of full scale) typically for 
crest factor  3.0.

Notes for capacitance specifications:
1 This function is only applicable for U1192A, U1193A, and U1194A models.
2 Overload protection: 600 Vrms for short circuits with <0.1 mA current
3 The accuracy of for all ranges is specified based on a film capacitor or better, and after the Null function is used to subtract
the test lead resistance and thermal effect (by opening the test leads).
