Notes for true rms ac voltage specifications:
1. Overload protection: 600 Vrms. For millivolt measurements, 600 Vrms for short circuits with < 0.3 A current.
2. Input impedance: 10 MΩ (nominal) in parallel with < 100 pF.
3. VZ_LOW input impedance: 3 kΩ (nominal).
Notes for ac current specifications:
1. AC current measurement not available for U1231A model.
2. Overload protection for 60 μA to 600 μA range: 600 Vrms for short circuits with < 0.3 A current.
3. Overload protection for 6 A to 10 A range: 11 A/1000 V; 10 × 38 mm fast-acting fuse.
4. Specification for 10 A range: 10 A continuous. Add 0.3% to the specified accuracy when measuring signals > 10 A to 20 A for 30 seconds maximum.
After measuring currents > 10 A, cool down the multimeter for twice the duration of the measured time before proceeding with low current
measurements.

Notes :
1. Overload protection: 600 Vrms for short circuits with < 0.3 A current.
2. 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 shorting the test leads).
3. The maximum display is 1200 counts.
